A black hole can feel like the most distant and unreal object you could ever think about, yet the way its darkness bends ...

Researchers are using black hole “shadow” images to test whether Einstein’s relativity remains unshakable. With next-generation telescopes, they hope to spot telltale signs of alternative physics ...

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

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 earliest test of Albert Einstein's general theory of relativity took place just four years after he published it. During ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

Online users have for years — "over and over again" — shared the quote with the famous physicist's name and image.

Interstellar comet 3I/ATLAS, which originated outside our solar system, has reportedly confirmed one of Albert Einstein's ...

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object ...

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.

For the first time, scientists have detected two black hole mergers with spins so unusual they may reveal a new generation of ...

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