Michio Kaku appeared on Part 1 of Einstein's Unfinished Symphony with the following interpretation of probabilities in quantum mechanics:
Wouldn’t this be impossible, even in principle? Mars at its closest is at a distance of 55.7 million km, and if particles are limited by the speed of light, wouldn't it mean that this event could never happen?The quantum theory makes even bizarre events possible. For example walking across the street we expect to wind up on the other side. However there is a finite calculable probability that you will dissolve and wind up on mars, dissolve and wind up on the earth again. Of course you’ll have to wait longer than the life time of the universe, but in principle, it could happen.
