Evidence that the universe is rotating was recently delivered by the James Webb Space Telescope (JWST), which found that two-thirds of galaxies are rotating in the same direction. This suggests a lack ...

The James Webb Space Telescope (JWST), launched in 2022, continues to reshape how we view the cosmos. Designed to look deeper into space and further back in time than any previous instrument, it has ...

"I think that the simplest explanation of the rotating universe is the universe was born in a rotating black hole," University of New Haven theoretical physicist Nikodem Poplawski, who champions ...

"One explanation is that the universe was born rotating. That explanation agrees with theories such as black hole cosmology, which postulates that the entire universe is the interior of a black hole." ...

Even a rotating cosmos has only a weak connection to the universe-inside-a-black-hole idea, however. Yes, black holes (and white holes) rotate, but it’s not straightforward how that rotation ...

Without a doubt, since its launch, the James Webb Space Telescope (JWST) has revolutionized our view of the early universe, but its new findings could put astronomers in a spin. In fact, it could tell ...

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.

In 1971, English mathematical physicist and Nobel-prize winner Roger Penrose proposed how energy could be extracted from a rotating black hole. He argued that this could be done by building a ...

General relativity predicts that the only rotating black hole solution is the Kerr spacetime. This means a black hole can be fully described by just two properties: mass and spin.

Black holes are mysterious objects – there’s a lot we don’t know about them. One longstanding question has been whether rotating black holes, which are so powerful they drag space-time along ...

That means nothing can sit still around a rotating black hole, including the "plates" that these cosmic titans feed from. Those flattened clouds of gas and dust surrounding supermassive black ...
