Show for Feb 27, 2011. Not Totally Insane: Physicist Anthony Aguirre on the New Cosmology
I thought I knew a thing or two about the universe: nearly 14 billion years old, started with the big bang, expanding at a certain rate, etc., etc. Turns out the story may be much more complicated, if the latest theories are right. What I thought I knew applies only to the observable universe, but outside that little patch of ours, things may be very different. Possibilities include varying rates of inflation, different physical laws, maybe entirely separate universes. Cosmologist Anthony Aguirre of UC Santa Cruz joins us to speculate on what’s out there beyond the horizon.
Not so simple: The universe may be a lot more complicated than this standard view suggests.
