Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

Scientists have observed a new type of black hole that is too heavy to have been born from a star but still too slim to … The ...

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

Traditionally thought to go silent after a brief flare of activity, some black holes are now being observed emitting new ...

The three examples the team highlighted in a new study describe supermassive black holes feasting on stars more than three times as massive as our own sun.The events, dubbed “extreme nuclear ...

So, as the black holes begin their deadly dance, the event horizons elongate and stretch toward each other. We understand what happens next only through complex computer simulations that monitor ...

New research suggests black holes may transition into 'white holes', ejecting matter and potentially even time back into the universe, defying our current understanding of these cosmic giants.

Physicists think the insides of black holes may be complex mazes of tangled strings in higher dimensions. Skip to main content. Scientific American. April 7, 2025. 3 min read.

If that black hole generation happened on the early side—in the first one-100,000th of a second—then we have the conditions we need for colorful black holes.

CENDES: So for the Gaia black holes, they're actually the closest black holes that we know of to Earth. So the closest black hole, about 1,600 light years from us.
