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 ...

Whenever someone talks about black holes, they almost always talk about the event horizon and the singularity. After all, ...

Spacetime isn’t something that exists; it’s a model for describing how events happen. Treating events as objects creates philosophical confusion and fuels misconceptions, such as time-travel paradoxes ...

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.

Albert Einstein, everyone’s favorite wild-haired genius with a mischievous grin, is more than just a pop culture icon whose legend lives on today. He’s arguably the most influential scientist of the ...

In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and ...

Astronomers have detected two extraordinary gravitational wave events that may have come from black holes formed in earlier ...

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 ...

New strategies may soon allow scientists to test dark energy theories within our own solar system, linking cosmic-scale physics to local observation. Science advances through a cycle of proposing ...

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object with mass pulls on every other object—a result that explained falling ...

The theoretical physicist and best-selling author finds inspiration in politics and philosophy for rethinking space and time.
