When blank it is black. white-screen share | improve this question edited Dec 2 at 7:32 Yufenyuy Veyeh Dider 1,525 4 9 24 asked Dec 1 at 18:29 Helier Robinson 1 1 closed as unclear what you're

What is the probability for an electron of an atom on Earth to lie outside the galaxy?

up vote 4 down vote favorite 1 In this youtube video it is claimed that electrons orbit their atom's nucleus not in well-known fixed orbits, but within "clouds of probability", i.e., spaces around the nucleus where they can lie with a probability of 95%, called "orbitals". It is also claimed that the further away one looks for the electron from the nucleus, the more this probability decreases, yet it never reaches 0 . The authors of the video conclude that there is a non-zero probability for an atom to have its electron "on the other side of the Universe". If this is true, then there must be a portion of all atoms on Earth whose electron lies outside the Milky Way. Which portion of atoms has this property? quantum-mechanics electrons wavefunction
