Q: If energy is neither created nor destroyed, what happens to the energy within our bodies and brains when we die?

Quick note: If you’re presently grieving, don’t read this.

The original question was: If energy is neither created nor destroyed, what happens to the energy within our bodies and brains when we die?  I think I understand that the metabolic energy tied up in our cells will be used in the decomposition process, but what about the electrical energy in our brains/bodies?  This would seem to be a measurable amount of energy that at the moment of death is no longer required by the body/brain and would have to go somewhere.  I’m not asking from a theological or spiritual perspective, but strictly as a question of physics.

… [is there] a measurable radiation of heat at the moment of death.  Do you know if there have been experiments that have measured the heat loss and correlated it to the known amount of electrical energy in the human body?


Physicist: Electrical energy is nothing special.  Just like the chemical energy in our bodies, it breaks down into heat.  For example, the heat given off by light bulbs (or electric heaters for that matter!) is a result of electrical energy.  When electricity is flowing to a light bulb, that’s where the electrical energy is going; it’s turning into light.  When you pull the plug (so to speak) what tiny, tiny amount of electrical energy there is in the wires runs out almost immediately.

The term “electrical energy” is actually a little vague.  So, to be specific, in our nervous system there are tiny ion pumps that maintain an imbalance of charges between the inside and outside of the nerve cells.  When a nerve cell fires, charges are allowed to suddenly flow through the cell membrane in a process called an “action potential“.  The way electricity flows along nerve cells is different from the way it flows down a telegraph wire (“inside-to-outside” instead of “along”), but whatever.  The point is, there are mechanisms that maintain an imbalance of charge (which is electricity waiting to happen), and that imbalance is drained a little bit every time the nerve fires.

Death (excluding spectacular deaths) isn’t instantaneous.  In fact, what with medical science, it’s become more and more difficult to even define when people are dead.  Time was you could define death as being a lack of heart beat, but people have come back from worse (by that metric, Dick Cheney has been dead for a while).  Death is more of a break-down of the whole system, as opposed to a sudden event.  The heart stops doing whatever hearts do when they’re not loving, oxygen and nutrients stop going where they’re needed, and in short order the nerve cells in the body lose the wherewithal to pump ions.  Like batteries that are no longer being recharged, they run down.  Nothing special.  Like every kind of energy, whether electrical, kinetic, sonic, or sports fever, the electrical potential in the body eventually becomes heat energy (it’s an entropy thing).

The energy we “carry around” takes the form of chemical energy like fats and sugars.  When our nervous system creates electrical energy we lose an equal amount of chemical energy.  So, rather than being energy itself, life is all about moving energy around from one form to another.

What this question is clearly really about is the fact that it seems as though there’s a fundamental difference between animate and inanimate people.  Admittedly, dead folk are a hair less energetic than living people (with some exceptions).  There are a few kinds of energy (surprisingly few), but spiritual energy doesn’t seem to be one of them.  In terms of physical energy, the difference between a living body and a very recently dead body is just a question of how that energy is being organized.  Living critters in general are very good at using chemical energy for things like moving, growing, etc.  Newly dead critters have about the same amount of chemical energy, it’s just that they don’t use it.  Instead, whatever comes along to consume the body uses it (whether that’s fire or decomposition or whatever).

There have been many, surprisingly callous, attempts to measure a drop in energy and/or mass leaving the body at the so-called “moment of death”.  However, these experiments have been vague and, much worse, unrepeatable.  The most famous is the experiment by Dr. Duncan MacDougall in which, by putting patients dying of tuberculosis on giant scales, he found that those patients lost 21 grams on average between life and death.  To be fair, homeboy had 6 data points (that is: people) and a lot of statistical noise, so his conclusions have about the same amount of statistical weight as “vaccines cause Autism“.  To date, there are no confirmable experiments that show that anything special happens during death, other than a general “shutting down”.  In particular, nothing that’s both “inspiring” and verifiable seems to suddenly leave the body when we die, materially or energetically.

    Terry- I agree..short and sweet good point

  2. Jacob Matysek says:

    Terry – I think in here some took the view the energy was converted (q where does it go)…. but in all honestly we are atill learning about certain fascists of sub particles… so there exists uncertainty even at science in the realms of mass less sub particles ie higgs fields… higs bosons… still per the laws of conservation… These particles exists at the tiniest fractions of a sec… so are extremely difficult to detect but may shes more light into this area of science :).

  3. The Polymath says:

    @James Robertson – Read, “Scanners Live in Vain,” by Cordwainer Smith. I believe you will find it fascinating that it was written in the 50’s.

    I’d personally presume that given there are more than three billion people with access to the internet, each commenter on this page is not at the same level of education, thus creating much fluctuation between perspectives of what can and cannot be, therefore, even given an imagination one can make some factual claims, and on the other hand, even given some factual information one can make some theoretical claims. Let’s all get along. However, on the side of “black and white-seeing” physicists, psychologists would say ambiguity is the discomfort from knowing there is something you don’t know that you wish you did, and I for one would rather fill in whatever blanks necessary with any-n-everything rather than be in discomfort…I mean…right…??? So, whatever “opinions” and “facts” are argued, it should only be fair to say that what can be empirically tested now and today should outweigh any theoretical, or even statistical, evidence otherwise.

    That being said, I want to give MY 2 cents too! =:D

    Included in majority of the comments is a mentioning of BURNING A BODY, and what happens to it when it goes through this process. This can actually be easily understood by looking at Antoine Lavoisier’s (1743-1794) burning log experiment. In this experiment, the log is weighed before and after it is burned. Obviously, the ashes of the log weigh less than before it was burned; the obvious question being, “where did the weight go?” The obvious (at least in physics) answer is, “it went from solids to gases.” The weight of the gases being released into the air by the flames as a log burns will equally match the a log’s weight “loss.” Hence, a body burned is simply going from solids to gases. (Ahem, heat…)

    I saw someone mention dark energy and just wanted to share this link: http://profmattstrassler.com/articles-and-posts/particle-physics-basics/mass-energy-matter-etc/matter-and-energy-a-false-dichotomy/ And actually, relating to this link, “energy” is a little ambiguous itself. Take potential energy for example: until it’s converted into some other form of energy (heat, sound, etc) it’s not really what we think of energy in everyday, simple terms. Rather, it’s an abstract thing, so….that should confuse things just enough more to cause everyone to flip their lid and cry, “Enough science, enough!” ;)~

    My only really personal thought on all this is the fascinating theory of infinity: mathematically possible, theoretically mind boggling. What I find second most interesting about infinity is that it goes both ways – backward and forwards. That means that time never really started, nor will it ever end. What I find most interesting of all about infinity is that theoretically it should apply to time and SPACE! Why is this fascinating? Not because of the obvious fact that if you move forward (or outwards) in space, and keep moving for infinity, it makes a very, VERY large space, but for the less-obvious fact that if you move backwards (or inwards), then theoretically there is no end to how small things can be. In this concept, I imagine relative to the size of atoms, there are subatomic particles the size of blue suns! In this respect, energy is in my opinion something that can and never will be fully understood, however, the least factual comfort you can give yourself about death is energy’s law of conservation. Otherwise, literally just tell yourself that what happens in the movie, “Chappie,” is possible and will happen in your lifetime, and you will feel a whole lot better.

  4. Rachel says:

    I know you said not to read this is if you’re grieving, (i’m 12, my dad recently died and all that stuff) but my family is Christian and I’m pretty much questioning everything in life. I saw the warning and wondered if i would continue to sob for another hour or two because of my fear of death but after reading the article, i actually felt… like death would be, like… peaceful. This was more comforting to me than a ‘heaven’ that lasts for ETERNITY while you forever hear angels play harps and you pretty much let go of anything that made you human or you stay there all happy ignoring that there are people, maybe close friends of yours, burning and being tortured in Hell. It didn’t seem like a paradise to me. Lately I’ve been thinking reincarnation would be nice. But HOLY SHIT the part about time never starting or ending gave me an existential crisis- here we go, more death anxiety. Maybe my anxiety about death will never be resolved.

  5. Queen Diamond says:

    The question was avoided, you never did clearly answer where the energy went. Like a car crash? The body just runs out/ shuts down like a robot? The energy? AGAIN, does it “vaporize”? A clear answer please. Or is this some sort of government secret, after all we never did learn this in school. When we did talk about cells and energy we were told the scientific explanation to life and the broad biblical explanation. Obviously one is going to keep us scared and give power to be controlled, and the other would bring up more questions in a chaotic form because no one would have power over anyone for what the biblical explanation is used as a border to keep us from thinking about it because it would be a truly “sinful” thing to do.

  6. The Polymath says:

    @Rachel – Not that it may resolve your anxiety about death, but consider the following:

    I’ve questioned religion a lot as well; however, in my conscience I’ve ALWAYS concluded several things.

    1. Metaphysics and natural physics, and ANY physics that deals with reality as we see-hear-feel-taste-and-smell does not ultimately reveal an answer of how to accept mortality. It may reveal answers of life itself, i.e. how it began, why it began, and how to manipulate it, but how to ‘deal with it all’ is not really included in this spectrum of enlightenment. — This said, a second conclusion implies..

    2. If essential happiness and contentment will not come from omniscience then why not believe the ‘impossible?’ If you’re not going to be happy or content otherwise then what harm does it do to have a little faith?

    Just for opinion sake, here’s how I see it:

    How can you truly teach any ‘thing’ anything without allowing them the experience? In my opinion, you can’t. For example, you can tell something or someone how to swim, show them how to do it, draw diagrams, program it in their head, ANYTHING, but it’s pretty clear that they won’t be able to swim until they get in the water and resist drowning. Maybe better put, Benjamin Franklin wrote, “Tell me and I forget. Teach me and I remember. Involve me and I learn,” and Albert Einstein said, “I never teach my pupils; I only attempt to provide the conditions in which they can learn.” So… How else could an omnipresent architect “involve” us in learning to be human or “create the conditions” for us to truly understand if not through experience and faith alone? If this architect simply created us to be perfect then the logical question I would have is what IS perfect and at which point in existence would be a good place for us to start???

    Point being..

    Let’s say an architect did build this universe and create all; we should then presume it was an omnipresence, particularly all-knowing regarding physics, and with this said this architect should then have made a never-ending loop of logic to deter any ‘thing’ from questioning its existence is ‘real.’ For example, if suddenly, today in the year 2015, some physically impossible occurrences began regularly happening and all of what we know to be ‘real’ was found to be unexplainable then global pandemonium would FINALLY occur. In other words, if I just popped my head through your screen at this very moment, winked an eye at you, and went back into the computer, and then did the same for every person on a computer at this very moment, I’m pretty sure the world would change. In what way the world would change is the point though. With no explanation possible we would have nothing but an omnipresent architect to believe in. We would suddenly have a purpose, e.g. whatever purpose this architect put us here for! Hence, our beliefs would change, our directives in life would change, HOW WE EVOLVED AND OUR NATURAL EXISTENCE would change, and all relevantly not because of faith, but because of evidence.

    Now..

    Consider then how one such omnipresence would resolve a TRUE testament of faith. (By leaving NO EVIDENCE OF HIS EXISTENCE, why of course!) And here’s the interesting part: an attempt to explain something with no evidence, especially a physical impossibility, is sure to seem theatrical, i.e. your attempted explanation to the authorities that a person’s face just popped out of your computer screen will surely sound just as impossible (and crazy..) as half-naked cupids playing harps in some other dimension!

    If you haven’t caught on by now, what I’m saying is that while some argue faith to be an impossible explanation for all that is ambiguous, I find that with an explanation for everything there is no such thing as faith. We will never learn how to truly be faithful if everything is proven. Instead, our faith will depend on something – on physics, on evidence, on seeing the light at the end of the tunnel – and in this case united faith, which can very well be another form of consciousness, will never become us. Another great quote from the very intelligent Albert Einstein is, “No problem can be solved from the same level of consciousness that created it;” we can never transcend without a new understanding.

    Rachel – Here’s one more from Albert Einstein: “The human mind is unable to conceive of the four dimensions, so how can it conceive of (the) God before whom a thousand years and a thousand dimensions are as one?”

    Have a good day!

  7. The Polymath says:

    @Queen Diamond – I think a clear explanation of where the “energy” goes may lie in this link: http://profmattstrassler.com/articles-and-posts/particle-physics-basics/mass-energy-matter-etc/matter-and-energy-a-false-dichotomy/

    You should not forget that “energy” is just a word for something, as are all words. What the word “energy” refers to may not actually be some “thing,” and therefore cannot come or go, so the question “where does it go,” may not be applicable.

    Think of it this way: when you die, where do your IDEAS go??? 😉

  8. John Fornaro says:

    I stumbled across this thread while doing some research on my hypothesis that Life has no mass and no charge, because at the moment of death, there is no measurable difference of mass and charge to be found in the Universe.

    I believe that the correct short answer to the question is that the mass and energy of the universe does not change when we die, and that life is a massless and chargless phenomena that we experience in this universe. The body decomposes and the living go on living.

    I have a few objections to the article/answer above, which I number for editorial convenience:

    The question today, 10-24-15 ARSH is:

    “If energy is neither created nor destroyed, what happens to the energy within our bodies and brains when we die?”

    The orginal question per the ‘Physicist’ on 11-8-15 ARSH was:

    “If energy is neither created nor destroyed, what happens to the energy within our bodies and brains when we die?”

    (1) I’m not seeing any differences between the two questions!

    The Physicist: “Electrical energy is nothing special.”

    (2) I did not notice the questioner asking if electrical energy is “special”. From an editorial and rhetorical standpoint, I prefer fewer words to more, unless the additional words add to an argument or support a proof.

    The Physicist: “The term ‘electrical energy’ is actually a little vague.”

    (3) The questoner asked about “energy”, which includes electrical energy, and the action potential is an electrical energy phenomena. Electrical energy is not vague at all.

    The Physicist: “What this question is clearly really about is the fact that it seems as though there’s a fundamental difference between animate and inanimate people.”

    (4) The question is “really about” the change of energy that accompanies the change from being alive to being dead.

    (5) Humor aside, there is a fundamental difference between life and death. There is no “seeming” to be either one.

    (6) The legal definition of life and death is only tangentially connected to the scientific definition of life and death.

    The Physicist: “To date, there are no confirmable experiments that show that anything special happens during death, other than a general ‘shutting down’. In particular, nothing that’s both ‘inspiring’ and verifiable seems to suddenly leave the body when we die, materially or energetically.”

    (7) Life is a special energy which cannot be measured by or even defined by science.

    Enjoy Life!

  9. I am writing a book about “Skull Art.” Your views on energy were enlightening, Thank you.

  10. Karen Selby says:

    Rachel – Please go to Micah Anderson Update and Prayer page. He actually died and went to heaven and then was revived. Please read it it is so helpful. There are a lot of different kinds of energy and there has been a lot of energy gone into his life.

  11. Delia Smith says:

    But if energy is neither created nor destroyed and just transformed then why don’t scientists believe in God? If energy is conserved then the belief in God seems to conform. If a person dies and energy transforms into billions of separate atoms yet those atoms are waiting to be transformed and connected in a billion years, then death is not the end of life. It may be the end of breathing etc but it is never the end of life because the possibility of life has already confirmed. If the possibility is confirmed then the probability of existence is included in the infinite nature of the universe and will never cease to exist. Therefore, there is no such thing as true death. If God is possible then the “existence of God” has a probability of existence. If the universe is infinite then wouldn’t it be more probable that God exists versus not? The mere proposal of God should be affirmation of the existence.

  12. leslie johnson says:

    I recently lost a friend a very very free spirit and he tole me even before he knew he was dying that “you can’t kill energy” that is all I know about Kenny GB

  13. Wes says:

    I admit the following has already been stated in other words:

    It seems to me that if one were living, and presumably prostrate, on an incredibly accurate weight scale, that mass would be constantly disappearing if one were not to eat or drink, i.e. add food mass. The reasoning for the mass disappearence is that the live body continuously radiates heat and that can only come from one source… chemical… and chemical heat comes from atomic mass.

    After death, the above steady bodily-mass loss should moderate as the deceased body cools, but the resultant radiation not entirely disappear, as natural biodegradation takes place to return mass back to primary stardust.

    Then even when dust-to-dust is done, perhaps a period of many years, the mass will still disappear extraordinarily slowly as the half-life of each decaying atom causes spontaneous radiation. Finally, when entrophy is complete, no bodily mass at all will exist… nor the scale to weigh it… just the radiation left from a universe that once was.

    Kinda depressing, no? Fortunately human creatures, which alone (so far) can comprehend our mortality, are usually well equipped with just enough release of dopamine, to provide us with delusions of well-being. We blissfully procrastinate our looming demise, giving off a little electrical brain heat as we think we are ok.

    Meanwhile, life is for the living. Even as mere cogs, we can all do good work unraveling nature’s machine.

  14. Karin says:

    Nice.

    And when the electricity turns off, the fuel is exhausted, the remaining potential energy moves into kinetic forms, like molecular interaction or subatomic forms, where ultimately a plant might grow if you want to find some hope.

  15. Mark says:

    I have for sometime been thinking about this very subject andvas such have subsequently found this forum.

    I am not an educated man so am probably coming to this from a different viewpoint than most here.

    I believe that our energy goes on when we die, I have no proof of this and I am not religious in any way shape or form. It’s simply what I feel to be true. Now here comes my question.

    If when we die we simply cease to exist and everything we were or are is no longer, then does that mean that we will have no memories of anything? That being said, and this is probably where I show how fool8sh I am lol. How then can I remember just now how can I feel how can I love because at some point down the line I will be dead and all my memories gone therefore even typing this and what I am feeling will be gone.. So what would be the point in remembering any of it just now??

    I think therefore I am. My conscious energy is part of me,what happens when this meat sack it resides in dies? Does the conscious energy die? Is there such a thing as conscious eneegy?

    You seem like clever folk discuss lol

  16. Bharatesh Adappa Danawade says:

    My answer to this question is simple. Say your family size 6 initially, u+mom+dad+bro+g. mom+g.dad, look at the energy levels(all kinds of energies) whole family put together. Say one of the member dies. The reason for dying is one of the member has newly entered in your family with certain energy or one or two or more members have acquired higher energy. Overall the energy of family remains constant the members in family keeping on changing by the rate of birth and death. This is true for a whole or part system(If u treat a family as part system and society as whole system)

  17. Jason Flatt says:

    So. Mr. Danawade,
    Are you saying that when a new member comes into your family, the exiting family member that is expiring at that time, energy transfers and is assimilated with the new family members energy come into the family? In lamen terms!!

  18. Sean Rice says:

    I think it’s a highly relevant question about where consciousness goes when we are truly and irrevocably dead according to the latest in medical science. The big thing that I’m going to say is that there seems to be a constant process AGAINST our own bodies thinking we are dead and going ahead with a measurable death process: As long as we aren’t dead, our bodies don’t do this. Once we are dead, we do. Coma patients don’t. People on respirators, don’t. Brain Dead people don’t. Dead people go through a process and people who are somehow “alive” do not.

    We can keep otherwise dead people ‘alive’ but not quite fix and recover them.

    What is it that happens so quickly to a brain that takes longer for the rest of the body? Why can’t it be recovered to a previous state?

  19. Jacob says:

    Your theory works well for conventional western families. However, the Human Population of Earth is getting bigger not smaller. Some families are having 13 plus kids. If each of their kids are having just more then 2 kids your theory becomes somewhat troublesome unless you were to say that this energy divides within a family group.

  20. shannon Parisette says:

    Reading all of the comments, I have yet to read answers because there really aren’t any. Only interpretations, speculations, and some good people out here who are smart and care enough to share what they are educated in. Here is the truth to the original question: It is unknown. Just like the “why” factor of our existance is unknown. There are a million different reasons of what we as humans can come up with for both questions. Science by far is the best bet over any religon but, for immediate answers for the sake of our comfort is: faith and spiritual seeking. We as humans are prone to it. It is almost innate which in itself makes it credible. So until we get some real answers LOVE is the only answer.

  21. Jason Flatt says:

    I’m sorry dude. You lost me. This discussion is about what happens after you die. Not a theological/political discussion about religious belief and why man is so evil for believing in some type of religion.

  22. luke says:

    hello,I”m schizophrenic, I’m also horriably uneducated, I’m also afraid that this notion of my creative energy being absorded by bad people when I die. please help inform me ,if you can.

  23. luke says:

    am I paranoid or just ignorant?

  24. The Polymath says:

    How about this –

    Picture a baseball sitting on a tee. Relative to the size of an average human holding a baseball bat, if the baseball is hit with a certain amount of force it moves at a certain rate of speed. Let’s say it moves at about 20 miles per hour, or about 9 m/s. To the human eye (if the human were standing still), the ball’s movement would instantly be observable. That is, it’s change from it’s initial state of rest would be obvious.

    Now take the same scenario, but apply the eye of a giant that is, let’s just say randomly, 100,000x the size of the observable universe. If that baseball (or any evidence of it being there) could somehow be seen by this giant’s eye, would that baseball’s movement be instantly observable? Or instead would such a relatively small thing need to move an enormous amount before its movement became apparent?

    This thought experiment might be a bad example, for if the eye could see such a small thing, it may be able to see the small thing’s movement as well.

    Instead of an eye “seeing” a baseball, how about if a baseball were hit in the direction of a nearby glass encasement. One would not need to see the ball move to know that some particular object was there. One could instead be aware of the opposing object (the ball) by either seeing or hearing the encasement break. How about the giant, however?

    Point is.. size matters. If we humans were simply sub-particles inside a much larger being, it’d be pretty hard to find out. Based on this, my bet is the galaxy filaments we see are just electrical impulses in a much larger process of reaction, and thus energy as we know it is itself a universe full of activity, just too small for us to see. And what personally gives me comfort about it all is, there’s no way to prove otherwise 😉

  25. Naman khulbe says:

    Here is your awnser
    I am 14, and i was studying abot law of conservation of energy. So i thought that why do we die. Well after researching about it, i read a scripture in the holy GEETA (i am a hindu by the way) that we dont know that why does our heart beats like why does it gets thoese vibration after every second even when there is no source of energy for it. So now what we humans gave this iternal energy a name called “soul”.
    Now here comes the theory part
    As we know that energy can neither be created or destroyed but can only be transformed or transfer. I believe in the term of multiverse which is again known in many terms like parallel universe, mirror world, alternate universe, alternate timelines ect.
    There are infinite universes in the bariers of space and time and so there are infinite alternate timelines. Maybe there is a timeline where earth is still ruled by dinosaurs or where humans are having lifespan of a 1000 years but the point is that we are living in one of these timelines so can it be not possible for energy to travel from this universe to the alternate one.
    Maybe when we die here, our iternal energy (soul) would travel to another dimension where we are actally getting another life.
    Think about it because somewhere at the end of the universe, you might find another dimension to live in (just giving the example of Christopher Nolan’s INTERSTELLAR)

  26. The Polymath says:

    “Chemical reactions that utilized available energy”

    Im sorry but…no.

    Please show me a link to some science and physics peer reviewed evidence that proves this. Chemical reactions are no more than chemical reactions. They are not what give us choice. Cells for example may be chemical reactions, but what causes a cell to resist death – this is no simple or even complex chemical reaction. Chemical reactions may provide the means for survival, but are not the cause for a cell to WANT to survive. Please do not confuse biochemistry with biology my friend. Biochemistry is a great window into the processes of biology, but is by no meams the cause. I beg you; don’t go there.

  27. The Polymath says:

    That was to Jasin Flatt I think btw

  28. The Polymath says:

    Oh no it was to Edward Jones! Lol

  29. Rationale says:

    Hello,
    I also do not believe the question has been answered, here is my twist on it.
    I have read every comment. I am not of a science background, just another educated and aware person.

    I like some recent comments regarding a honest observation about there being no concrete answer to the actual question. There is a lot of science to prove the processes the body goes through in certain death, but not what keeps the body living in the cases mentioned like coma and brain death.

    I hope someone can clarify whether or not science has a definite answer for whether or not the memories, feelings, etc. turn into some form of measurable energy that can be quantified in the decomposition process. And if there is no science to prove it, please be honest.

    Here is my question/angle on it:
    I am afraid to put the “word label” on what this question really is ASKING SCIENCE FOR AN ANSWER due to the per-conceived notions and assumptions that go along with the “word”…
    GHOSTS:
    Much of the world is quite divided on this theory. When science is quoted to disprove the ghost theory, only to fall short of opposing data, yet somehow still boast discrediting the opposing theory, it becomes frustrating.
    Does the scientific community have theories regarding “spirit” energy decomposing with the rest of the body?
    If not, truthfully admit to not having a proven theory that our collection of memory energy, or “spirit” dies. There is only an increasing amount of technology out there that is used to read imbalances in energy levels in normal circumstances (seeing ghost energy anomalies).
    Truthfully admit that the ghost theory has yet to have a scientific theory to disprove it.

  30. dave says:

    So from the ” Physicist’s” quite scientific and straight forward answer, if I were to eat someone after they have died, I would in fact consume all of their left over energy and it would turn into other forms of energy in my body?

    Sorry for the horrible question but I am asking from scientific point of view.

  31. Error: Unable to create directory uploads/2024/04. Is its parent directory writable by the server? The Physicist says:

    @dave
    That’s exactly right and super gross. Our bodies store and use chemical energy and that’s exactly what you’d gain. Assuming you don’t get caught.

  32. justin says:

    how can energy be destroyed in the first place if it is not created?.so as we know that there is energy so it is being created and does get destroyed people are to simple minded to figure it out and where does the energy go well as how about this it just simply turns into gas.

  33. Very interesting conversation!

    I am currently grieving a loss, and I realize that my grief is my own. That is, wether or not my friend’s energy has fizzled or transcended, my grief is a product of my own conscious which allows me to ‘miss’ the person who is no longer sharing my physical realm.

    At first, the metaphor of a light bulb burning away the remaining energy after it is unplugged was less than comforting. But a lightbulb, as far as I know, does not have a conscious, a personality or other unexplainable sense of being. So I find the metaphor lacking. Furthermore, the lightbulb is dependent on an outside energy source, which doesn’t actually burn the energy. Unless I have been mislead, the energy flows through the lightbulb and back out to the grid, lighting the conductor when its switch is ‘on’ but then traveling onward – not burning away. So that final glimmer of light after it is unplugged, as far as I can tell, would be less about burning away that last bit of energy and more likely a visible effect of no longer having energy traveling into it.

    I too, like many others commenting, am not religous or formally educated in science or mathematics. I’m sure that’s probably apparent.

    Thanks again for this article and the comments.

    I have experienced more death of people (and pets) that were my lifelines than anyone should have to deal with in a lifetime. Interestingly, some form of energy in each case has presented itself strongly soon after death, ie. my late husband’s wristwatch with a long dead battery sounding it’s alarm and returning to dormancy after I found it. These occurrences have always become less powerful and happen less often over time until finally disappearing. In my opinion, everyone is somewhat right about this subject. “Energy diminishing”, “ghosts”, “space”, “dimensions” and “changing the world”. Without faith in something, we stay unhappy and afraid. For me, the signs I’ve experienced give me faith that my loved ones are waiting for me in the clearing at the end of my path. And that’s enough to encourage me to make my life extraordinary. Thank you all for this insightful experience.

    Very interesting.
    Here are my 2 cents.
    What makes you, you, is your brain, memories, experiences. So If you die you will no longer be you, right? The energy that makes your brain works will leave your body. It makes sense what Im saying?

    How the hell would our world be if we didn’t have no more stars? Would our world not produce enough energy and we all die or what?

  37. Aldy Permana says:

    A simple answer is through the decomposition of the body. It occurs straightly after death. Bacteria and fungi plays an importing role in the decomposition of body. Some insects might also be involved the process. As energy cannot be created or destroyed, it is transferred to other forms of life and creatures through this process.

    Science cannot prove that having energy equals to having life since every object in this planet contains energy but might not be a living organism. The fan in my room has electrical energy but is not alive. But its energy might come from the death of living organism. Let’s say the energy comes from coal. Coal itself was formed from a prehistoric vegetation millions of years ago. So the energy of millions of years ago are still running our electrical system. Thus, energy is transferred or changed to another form.

    Energy alone cannot define life. Life is very complex. It involves all the aspect in our universe.

    Living things are made up of atoms and at death the atoms go back into the earth. The very essence of who we are has nothing to do with energy or atoms and has everything to do with our spirit. The life is not artificial

    What an amazing discussion. Like the 12 year old girl that wrote before me, I too am grieving for a lost father, and while I am much, much older, I miss him very much.

    That being said, I have pondered this question of energy and death for many years; way before my dad was diagnosed with cancer. However, one afternoon, just before his death, I jokingly reminded my dad of my childhood fears of death and dying. As I grew older this morphed into the question at hand (or at the beginning of this stream of discussions). The conversation conversation with my dad went something like this,” Hey dad, do you think you could send me some kind of sign?” With a smile he answered,”I’ll see what I can do.”

    Well my dad died on May 19th at about 2:48 in the morning. It was a clear beautiful night. I mention this, because a few minutes after dad died all the lights went out in our house. We have a generator, and like clockwork it started, but then the electricity came back on about 5 minutes later and the generator shut off.

    About five minutes later, our hospic case worker arrived, and he was pretty freaked out because he watched a bolt of light streak up the drive and across the road in front of him.

    As time went on, I realize that our generator was not putting itself through a test every Thrusday like it was supposed to. The repair main said that it looked like system had experienced some type of electrical overload.

    I’m sure most of you can guess how this made me feel. I may not have an exact answer of what happens to the energy when you die, but I am very certain that it is more than modern science or physics or mathmatics can explain today. With that, I’ll leave you with this final comment…I’m part owner of an energy company. I think my dad chose a fitting sign that there is more still ahead.

    if energy isn’t created then where do babies get their creative energy, if its the parents then when bill gates fathered kids did he lose creative energy if so why did his creativity not go down?

  41. Sam says:

    Very little energy is used that comes from the sperm, there are usually more than 20 million sperm per ejaculation and only the head which has almost 0 energy mates with the egg in creating the zygote. Except for the male dna almost all energy is generated from egg’s Mitochondria(energy). almost 100% of the sperm mitochondria is in the tail and dissipated working it way to mate with the egg. The female mitochondria destroy’s the rest of the sperm’s mitochondria and tail. It is assumed that energy is absorbed as waste.

    What about the electrical impulses that are in the bod?. Where does that go? Even Einstein believed in something more after death. His belief might have been more scientific that spiritual but he still believed. I trust his judgement more than a faceless person on the web.

  43. Sam says:

    In general the electrical and chemical energy in a human body is disseminated in a variety of ways. we first evacuate all orfices as waste, then decomposure starts as heat and micro organisms began to take on the varies energies. when electrical energies can no longer maintain stability close to 100% is dissapated as heat. “The Mathimatician” may edit out my next remarks.

    I’m guessing you are looking for an additional answer that some of the additional electrical impulses head out to parts unknown. There is a theory, neither proved or disproved, that a set of electrons & positrons collaborate in a quantum process called pair annihilation, within seconds nanoseconds of death, and transform to coherent photon energy first and then gamma ray energy. This is thought to be a pure EMF and no mass.

  44. Ron Ranstrom says:

    I stumbled upon this thread having googled the question of what happens to your body’s energy upon death. About a year ago my mother passed away. Her first day in the hospice room (Wed), my sister randomly made a cross out of those plastic/metal thumb tacks on a cork message board hanging on the wall next to my mother’s bed. On that Sat, my mother was now incoherent and shallow breathing, we (8 Family members) heard a loud snap that came from the corner of the room, as loud as a mouse trap snapping, at this moment my daughter whom was sitting in a chair with her back to the message board was holding my mother’s hand had a tack land in her lap(about 4′ and a 45 degree angle away). Here it’s the center pin of the Cross. Eight of us witnessed this, I couldn’t recreate the sound, no explanation, some sort of “sighn”?

    Energy; decomposition requires energy, breakdown of cells require energy, if cremation occurs then that is a release of heat therefore energy into the surrounding environment. If burial then microorganisms consume said breakdown of cells etc (aka transfer of energy). Electrical synapses neutralize because there is no longer anything to drive the current. NO religious experience there; sorry. Not sure why this is such a hard question. I’ve read most of the questions. Believe what you want; coincidences do happen… but science is what it is… religion is up to debate most of the time. Do not mean to offend but if offense is taken then do you take offense to another type of religion? Find faith in what makes you feel comfortable; invoke reasons that help you live your life. Facts are mostly what I believe in. I do believe that if some sign of the person that you recently lost was resurfaced if you delve deep enough you will realize that it was already there even before you lost that person.

    Why not? You are typing words, making your voice heard now. Before our time we remembered our family by words passed down or journals/diaries. The same is true for today. Your family will remember you by memories. You will not be remembered by your present thoughts unless you impress those thoughts upon someone. How can someone hear you unless you use your voice? As to your question of

    “How then can I remember just now how can I feel how can I love because at some point down the line I will be dead and all my memories gone therefore even typing this and what I am feeling will be gone.. So what would be the point in remembering any of it just now?”

    Why the hell do you suppose poetry, songs, plays, operas, art, literature, etc came about??!! People want to know that their feelings were remembered. How am I supposed to somehow conjure how you feel after you are dead unless you leave something? AND THE POINT OF REMEMBERING is to know how you lived while you are alive. So in short I don’t think there is anything to conscience memory or energy after death. You leave behind what you choose to leave behind. Did I miss anything from your post? Please let me know. Thx

    The easy answer is oxygen. If a patient is in a coma or even brain dead all of the other systems in the body can still function in part due to oxygen being supplied to the body. This can be nasal cannula or ventilator. Every living organism needs oxygen. They also supply other nutrients through IV to keep the body functioning. Although the brain is the “power source” of the body most of the key organs can keep functioning with oxygenated blood being pumped via ventilator. Other organs need help from blood pressure and hormone drugs. I do not dispel faith in a humans will to survive; I have heard of this before. Believe me; if it were my son or my husband I would fight to the death before they pulled the plug.

    What is even more mysteries to me is that there is no measurable difference between life and death, and yet, “I” know there’s a difference.

  49. Kelly says:

    Could it be that the energy that disperses after life ends (any life) becomes a part of dark energy, and thus, the expansion that appears to be happening in space?

  50. Bizee says:

    This is a pretty cool thought. I dont know the answer clearly but I like your thought about it.
