Q: What is quantum immortality?

Physicist: A common refrain in quantum theory is “anything that can happen does”.  Shockingly, and with total disregard for our own human experience, this seems to be true.  When you consider what this means in the context of living and … Continue reading

Q: With entangled particles, can you tell when/how the other particle is measured?

Physicist: Nope!  You definitely can’t. Almost without exception, when you hear about quantum entanglement it’s described as some kind of communication or connection.  Generally along the lines of “when you affect one entangled particle it instantly affects the other” or … Continue reading

Teleportation! In space!

Physicist: This isn’t a question anybody asked, just an interesting goings-on. A few weeks ago QUESS (QUantum Experiments at Space Scale) began teleporting quantum information to and from the Micius satellite and between ground stations 1200 km apart.  This is … Continue reading

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
