Something like 13.8 billion years ago, all energy in the universe was condensed into a single point. Until suddenly it wasn’t. The resulting detonation was the most massive explosion in all of the ...

Using a Socratic approach, we survey the best scientific ideas in physics regarding how a universe could arise from literally “nothing.” Key topics include: - The meaning of "nothing" in physics, ...

In your interview with Roger Penrose, he points out that “nobody knows where the fundamental constants of nature come from”. The sheer improbability of their being so finely tuned for life has given ...

How does the universe work? What rules make what we know fit together? In this hour, we'll talk with physicist and author Gordon Kane about one theory—supersymmetry. We'll find out what it is, what it ...

A new study by physicists highlights one way that cyclic or 'bouncing' cosmologies fall flat. 'People proposed bouncing universes to make the universe infinite into the past, but what we show is that ...
