If an Electron Can Be in Two Places at Once, Why Can't You?

Electrons do it. Photons do it. Physics legend Roger Penrose thinks he finally knows why you and I can't do it too.

About 80 years ago, scientists discovered that it is possible to be in two locations at the same time — at least for an atom or a subatomic particle, such as an electron. 

For such tiny objects, the world is governed by a madhouse set of physical laws known as quantum mechanics. At that size range, every bit of matter and energy exists in a state of blurry flux, allowing it to occupy not just two locations but an infinite number of them simultaneously. 

The world we see follows a totally different set of rules, of course: There’s just one Oxford University, just one car, just one Penrose. What nobody can explain is why the universe seems split into these two separate and irreconcilable realities.

 If everything in the universe is made of quantum things, why don’t we see quantum effects in everyday life? Why can’t Penrose, made of quantum particles, materialize here, there, and everywhere he chooses?
