The image of supermassive black hole Sagittarius A * was created using data from the Event Horizon Telescope Collaboration.

"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.

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

NASA’s Webb Telescope found early galaxies rotating in the same direction, reigniting theories that our universe may exist ...

The James Webb Space Telescope has observed a surprising alignment in the spin directions of ancient galaxies, challenging ...

But the Webb data shows something eerily organised, as if the universe has a preferred direction. And this raises one terrifying possibility: that the entire cosmos may be rotating as one, bound ...

There are new hints that the fabric of space-time may be made of "memory cells" that record the whole history of the universe ...

Black holes are invisible, yet they are among the brightest things in the universe. If a star wanders too close to a black hole, it gets torn apart in a fireworks show called a tidal disruption event.

In 2019, the Event Horizon Telescope (EHT) Collaboration released the first image of a supermassive black hole at the center of the galaxy M87.

Hence the term black hole. But if you were to look at a black hole, it wouldn’t be a literal black hole. You would see something in space—a sphere. And this sphere’s boundary would be defined by ...
