thick ring surrounding the black hole, which is consistent with the expected appearance of a Kerr black hole—a solution to Einstein's equations that describes rotating black holes. This finding ...

Astronomers have identified the closest ever Einstein ring, a rare phenomenon where light from a further-off galaxy is bent by the gravity of a galaxy closer to Earth. The ring was previously ...

This quest is performed by Euclid, with extraordinary observations that deliver unusual stuff – like an extraordinary Einstein ring. An Einstein ring is a gravitational lens phenomenon caused by ...

Black holes continue to captivate scientists: they are purely gravitational objects, remarkably simple, yet capable of hiding mysteries that challenge our understanding of natural laws. Most ...

He answered: "The mathematics says there is a parallel universe on the other side of the black hole." "Einstein's equations predict the Earth might be able to enter the ring," if a black hole were ...

"These observations provide a more complete picture of the black hole's environment ... made using Albert Einstein's theory of gravity, general relativity. That ring was still present in the ...

One of the key areas of investigation is the Kerr ... black holes to two-dimensional CFTs. For instance, studies have shown that the properties of rotating dyonic black holes in the Einstein ...
