Black Holes

Black holes in the extraordinarily distant cosmos are out of tune with their host galaxies, offering insights into their formation

Before leading the Manhattan Project, J. Robert Oppenheimer co-authored a paper explaining that the most massive stars must eventually become what we would now call a black hole

Researchers, using the galaxy as a detector, believe they have detected gravitational waves from monster black holes for the first time.

Astrophysicists are tuning in to a never-before-seen type of gravitational wave spawned by pairs of supermassive black holes

Particle by particle, all matter may eventually disappear, according to new calculations

Some of the most violent cosmic collisions occur silently in the vacuum of space, but with the right instrumental ears, we can still hear it happen. Here’s how.

The laws of physics allow time travel. So why haven’t people become chronological hoppers?

Using machine learning, researchers have now created a much sharper portrait of the supermassive black hole at the center of the galaxy M87

Scientists may have spotted two pairs of merging dwarf galaxies, each pair with a duo of soon-to-collide black holes

A lab-made black hole is beyond current technology but could be possible one day

The way we teach quantum theory conveys a spookiness that isn’t actually there

These merging supermassive black holes are among the closest ever observed and could help unlock deeper secrets of cosmic history
