Is it possible for atoms to disappear?

No, atoms can’t disappear. However, atoms can decay. Atoms can lose or gain particles.

Do atoms have thoughts?

Originally Answered: Are thoughts made out of atoms? Assuming a physical nature for thoughts, the answer would be NO. Since the brain largely operates on electrical impulses between neurons you could reasonably say they’re made of electrons though. Assuming a physical nature for thoughts, the answer would be NO.

Do you miss the “delayed-choice quantum eraser?

Most were small and nobody will really miss them, but I did feel bad about eliminating my discussion of the “ delayed-choice quantum eraser ,” an experiment that has caused no end of confusion. So here it is, presented in full. It’s a bit too technical for the book, I don’t know what I was thinking!

What is a ‘delayed choice experiment’?

This was the basis of a number of tests described as ‘delayed choice experiments’. In this latest version, the researchers split a pulse of laser light using Italian Space Agency’s Matera Laser Ranging Observatory (MLRO), so a photon could either take a shorter path, or be sent on a slightly more convoluted detour.

How did physicists test quantum light’s weirdness?

Quantum physics’ two-faced nature has been put to the test over and over again, and every time it’s still damn weird. This time physicists have gone to some lengths – literally – by splitting and merging light and then bouncing it from a satellite before testing its odd-ball properties.

What is a quantum eraser experiment?

By choosing to do our measurement in this way, we have erased the information about which slit the electron went through. This is therefore known as a “quantum eraser experiment.” This erasure doesn’t affect the overall distribution of flashes on the detector screen. It remains smooth and interference-free.
