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

Some physicists think our reality is a kind of cosmic hologram, with space, time, and gravity as manifestations of a ...

Neutron stars are timelike matter with a maximum mass of about 2.34 solar masses in quantum chromodynamics (the strong color ...

Very massive stars are cosmic "rock stars" that live fast, die young and leave black holes in their place. During this ...

A controversial theory suggests the observable universe is the result of matter rebounding after the collapse of a black hole ...

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

A new generation of black hole research is unfolding thanks to artificial intelligence, massive simulations, and cutting-edge ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity.

The black hole in question lies in the distant Seyfert galaxy PG1211+143, about 1.2 billion light years from Earth. Using the European Space Agency’s XMM-Newton X-ray Observatory, the University of ...

Astronomers at the University of Hawaii uncovered black hole events so packed with energy, they were the biggest explosions ...
