Brian Cox - Is The Universe Infinite?

Brian Cox - Is The Universe Infinite? Subscribe to Science Time:    / sciencetime24   Brian Cox talks about the possibility of the Universe being infinite. Of course the question, does the cosmos go on forever, is an age old question in philosophy and science. The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. But what lies beyond the observable Universe? Brian Cox explains how big the Universe really is. What we know for certain is that the Universe is bigger than we observe it to be, essentially because the farthest edges of the universe we can see don’t look like edges at all. The observable universe is still huge, but of course it has limits. That’s because we know the universe isn’t infinitely old. We know the Big Bang occurred some 13.8 billion years ago. #ProfBrianCox #Universe #science Sources: Brian Cox at the JRE:    • Joe Rogan Experience #1233 - Brian Cox   "Professor Brian Cox at BETT 2020" by p_a_h is licensed under CC BY 2.0 https://commons.wikimedia.org/wiki/Fi...
