Episode notes

In any finite system, you get something called a Poincareu occurrence. This is where everything comes back to where it began. And so if after universe is a finite system, which we believe it is, then that means that the universe will undergo a Poincreu occurrence. The time it would take for that PoincareU occurrence is not enough time for you to finish the game of trees. So the universe was reset itself. But do we really know what they are? Can't calculate them? What does it mean to know what a number is?

It’s a big universe we live in, so it comes as no surprise that big numbers are needed to describe it. There are roughly 10^22 stars in the observable universe, and about 10^88 particles altogether. But these numbers are nothing compared to some of the truly ginormous quantities that mathematicians have found to talk about, with inscrutable names like Graham’s Number and TREE(3). Could such immense numbers have any meaningful relationship with the physical world? In his recent book Fantastic Numbers and Where to Find Them, theoretical physicist Antonio Padilla explores both our actual universe and the abstract world of immense numbers, and finds surprising connections between them.
