In a landmark achievement, astronomers have noticed light bending in an unexpected manner, one that doesn’t align with the predictions made by Albert Einstein’s theory of general relativity. This ...

One hundred years ago today, Albert Einstein finished a scientific paper that would change the world. His radical insight into the nature of light would help transform Einstein from an unknown patent ...

From early experiments with lanterns to Einstein’s revelations about space and time, the speed of light has proven to be far ...

An international team of astronomer’s dark matter halo discovery an unusual astronomical Einstein Cross phenomenon: a galaxy ...

For the first time ever, astronomers have directly detected light from behind a supermassive black hole. The discovery proves Albert Einstein's theory of general relativity was right — again. Using ...

A prediction made by Albert Einstein in his theory of general relativity has come true as astrophysicists have detected light coming from behind a black hole. A team of scientists made the analysis ...

As early as 1916, Albert Einstein proposed the concept of gravitational waves within the framework of his general relativity. He envisioned that when two massive celestial bodies, such as black holes ...

Just days after Albert Einstein's theory that nothing moves faster than light was called into question by a startling neutrino experiment, the long-dead physicist might have come to his own rescue.

Albert Einstein’s theory of relativity is built on the idea that the speed of light is a constant – and always remains the same. The speed of light has been used to measure the age of the universe – ...

CAPE CANAVERAL, Fla. — Europe's Euclid space telescope has detected a rare halo of bright light around a nearby galaxy, astronomers reported Monday. The halo, known as an Einstein ring, encircles a ...

A beautiful, "bejeweled" halo of warped light generated by a monster black hole takes center stage in one of the latest James Webb Space Telescope (JWST) images. The luminous loop, which is strikingly ...
