Brian Keating: Was the Big Bang Really the Beginning?
Notas do episódio
Is it true that the Universe may not have originated the way we usually think — and that the Big Bang is only one piece of a far more complex picture?
In this episode, I talk with American astrophysicist Brian Keating, Professor of Physics at the Center for Astrophysics and Space Sciences at the University of California, San Diego, about the origin of the Universe, the nature of the Big Bang, the multiverse, and the future of the cosmos.
We discuss:
- How could the Universe have emerged from "nothing"?
- What gave rise to the Sun and the Earth?
- Why might the Big Bang not have been the event we usually imagine it to be?
- What could have existed before the Universe formed?
- What are the different levels of the multiverse?
- Could there be universes that formed without a Big Bang at all?
- What is happening to dark energy — and could the Universe one day collapse?
- How stable is everything we consider reality?
