This is a familiar process: stars collapse into black holes, which are among the most well-understood objects in physics. But what happens inside a black hole, beyond the event horizon from which ...

“We are not witnessing the birth of everything from nothing,” Gaztanaga writes. “But rather the continuation of a cosmic cycle.” And if he’s right, the Big Bang wasn’t our beginning.

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...
