One of the most perplexing discoveries in modern astronomy has been finding supermassive black holes, some weighing billions ...

The universe seems to be spinning, and that could explain what dark energy is and why it's weakening while revealing our ...

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

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

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

From this, they calculated M87*’s spin parameter, a measure of how fast a black hole is rotating. The result: 0.8 on a scale from 0 to 1, with 1 being the theoretical maximum.

The concept of a rotating universe may hold the key to understanding dark energy and our position within the multiverse.

Over time, the black hole’s rotation—called spin—can increase dramatically. According to models, a non-rotating black hole can reach near-maximal spin as it grows to roughly 2.45 times its ...

In 2022, they presented an image of the black hole in our Milky Way, Sagittarius A*. However, the data behind the images still contained a wealth of hard-to-crack information.

For decades, he hid his time-travel obsession. Now, he is challenging the assumptions that underpin our universe.
