Solar eclipses occasion lots of excitement and pique the public's interest in astronomical phenomena. Eclipses can also expand our understanding of the universe in profound ways. In fact, astronomical ...

Black holes are considered cosmic gluttons, from which not even light can escape. That is also why the images of black holes ...

Twin black hole collisions detected in 2024 have provided the sharpest-ever test of Einstein’s theory while revealing new details about how black holes form and spin.

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window ...

The first image of a black hole, captured in 2019, has revealed more support for Albert Einstein's theory of general relativity. The new finding has suggested his theory is now 500 times harder to ...

Interstellar object 3I/ATLAS has seemingly confirmed Einstein's general relativity by exhibiting gravitational lensing as it neared the Sun. However, the observed light bending exceeded predictions by ...

The French philosopher Renee Descartes took some time before convincing himself that he really existed. Or, in his words, “Cogito, ergo sum,” which is Latin for I think, therefore I am. While most of ...

Albert Einstein’s theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly on all scales. When you purchase ...

Einstein was self-taught and wrote in his journals that if he were not a physicist, he would probably be a musician. His ...
