Black Holes

Black holes and quantum mechanics present a paradox about the preservation of information

A cosmic explosion known as GRB 250702B is by far the longest gamma-ray burst astronomers have ever seen—if it’s even one at all

Huge eruptions from the Milky Way’s supermassive black hole in the distant past may have sterilized much of the inner galaxy

Voracious supermassive black holes light up the cores of “active” galaxies across the universe. How we see them, however, is a matter of perspective

A controversial prediction about black holes and the expansion force of the universe could explain a cosmology mystery

Gauging the mass of a black hole is tricky, but astronomers have devised multiple methods to measure the heft of these galactic gluttons

Spacetime ripples from a black hole collision across the cosmos have confirmed weird aspects of black hole physics

Some black holes get extremely massive. Is there an upper limit to their growth?

JWST observations of light sources before the first galaxies should have formed are raising new questions about our galactic origins

Scientists are uncovering how spinning black holes launch jets, warp spacetime and shape the cosmos

After 10 years of gravitational-wave research, the LIGO Lab team at MIT is getting ready for the next generation of detectors.

A U.S. gravitational wave detector spotted a collision between fast-spinning “forbidden” black holes that challenge physics models
