Want to know how the world is going to end? Just ask Russian cosmologist Alex Vilenkin
. If it’s our own universe you’re talking about, well, it’s called the big crunch
, and it’s going to be hot hot hot! But if it’s the multiverse
, that infinitely expanding, infinitely varied and infinitely populated sea of universes, well, guess what — there is no end. Isn’t that reassuring??
Vilenkin is Professor of Physics and Director of the Institute of Cosmology
at Tufts University
, and also the author of a new book, called Many Worlds in One: The Search for Other Universes
. He’s also a former zookeeper. And – lest I forget – he was blacklisted by the KGB
to listen. (29:45 minutes)
