Q: Does quantum mechanics really say there are other “mes”? Where are they?

Physicist: As much of a trope as “Other Quantum Worlds” has become in sci-fi, there are reasons to think that they may be a real thing; including “other yous”.  Here’s the idea. Superposition is a real thing One of the … Continue reading

Q: Are some colors of light impossible? Can any color of light be made?

Physicist: Just so we can talk about this using physics rather than poetry, for the sake of this article “color” really means “frequency”.  Light frequency is a bit more objective than color and includes things we can’t see (like ultraviolet). … Continue reading

Q: What are “actual pictures” of atoms actually pictures of?

Physicist: Actual pictures of atoms aren’t actually pictures at all. There are a few good rules of thumb in physics.  Among the best is: light acts like you’d expect on scales well above its wavelength and acts weird on scales … Continue reading

Q: If atoms are 99.99% space, what “kind” of space is it? Is it empty vacuum?

Physicist: This is a bit of a misnomer. When we picture an atom we usually picture the “Bohr model”: a nucleus made of a bunch of particles packed together (protons and neutrons) with other particles zipping around it (electrons).  In … Continue reading

Q: If all matter originated from a single point, does that mean all matter is entangled?

The original question was: All matter originated from a single point, does that mean all matter is entangled? If it is why do you need to create new entangled practices when doing experiments? Are there different types or degree’s of … Continue reading

Q: Before you open the box, isn’t Schrödinger’s cat alive or dead, not alive and dead?

The original question was: If I don’t open the lid of the bunker, the cat inside is either dead OR alive.  Why does Schrödinger say that the cat is both alive AND dead if I do not perform the act of … Continue reading
