Discover how the "zero change" assumption breaks down on logical and quantum grounds, rendering closed timelike curves pseudoscientific.

Black holes live forever, at least according to general relativity. Once material crosses a black hole's event horizon, it is trapped forever, until the last day of cosmic time. But we know that isn't true. General relativity is a classical model.…

Black holes evaporate through Hawking radiation, meaning their days are numbered. But a new study finds they could enter a metastable stage where they look similar to white holes.

A link between particle physics and gravity equations, called the double copy, applies to Hawking radiation, creating a new way into black hole puzzles.
