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

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

The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

Earlier this year, new research suggested a potential solution to one of the most troubling aspects of modern physics — that ...

Could Mysterious Black Hole Burps Rewrite Physics?

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

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

The colossal black hole lurking at the center of the Milky Way galaxy is spinning almost as fast as its maximum rotation rate ...

"We would need to consider the possibility that the source was created (or trapped as a primordial black hole) by a highly advanced technological civilization," Harvard's Avi Loeb writes.

The findings suggest black holes could provide a cheaper, natural alternative to billion-dollar particle colliders, if we can figure out how to harness them.

Crucially, this bounce occurs entirely within the framework of general relativity, which applies on large scales such as ...
