The bold question-askers at What If imagine the cosmic consequences of a collision between a black hole and a white hole.

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

Black holes, once purely theoretical, are now observable phenomena, offering insights into the universe. Their intense ...

A groundbreaking simulation reveals how neutron star mergers forge black holes, generate gamma-ray bursts, and scatter gold ...

In a recently published paper in Physical Review Letters, scientists propose a comprehensive theoretical framework indicating that gravitational wave signals from black hole mergers are more complex ...

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...

A high-speed crash between two dwarf galaxies might explain a unique feature in space – and provide useful information on ...

Sagittarius A* is spinning near top speed with its rotation axis pointing towards Earth. Event Horizon black hole project executed over 12 million computing jobs using distributed computing.

The colossal black hole lurking at the center of the Milky Way galaxy is spinning almost as fast as its maximum rotation rate. That's just one thing astrophysicists have discovered after developing ...

There are objects in our universe so dense that not even light escapes through them. These oddities, known as supermassive black holes, can weigh billions of times more than our sun. Scientists have ...

Could Mysterious Black Hole Burps Rewrite Physics?

Whereas detectors like LIGO and Virgo can capture the final stages of a black hole collision, LISA will be able to track them for years before they merge as they spiral in towards each other ...
