Black hole facts so wild that physicists themselves still find them deeply disturbing ...

What if wormholes were never cosmic tunnels at all? New research suggests Einstein and Rosen’s famous “bridge” may actually reveal something even stranger: time itself could flow in two directions at ...

Black holes have a problem that physicists still cannot explain. According to Stephen Hawking’s famous prediction, black ...

Researchers have developed a technique to analyze how black holes "ring" when they collide and merge: one of the universe's ...

The most massive black holes in the universe detected by the ripples they make in spacetime were not born directly from ...

The biggest black holes in the Universe may be built through chains of violent mergers deep inside crowded star clusters.

For just one-tenth of a second in May 2019, the universe delivered a signal that did not fit the usual script. LIGO and Virgo recorded a gravitational wave from GW190521, but unlike the familiar ...

The Universe’s biggest black holes may not be born giants after all. Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black holes ...

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

For a half-century, scientists have investigated ways to solve the black hole information paradox—the idea that when black holes evaporate through Hawking radiation, the information inside them ...
