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

In the mid-19th century, Bernhard Riemann conceived of a new way to think about mathematical spaces, providing the foundation ...

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, ...

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

Even though we can explore the universe with great precision, there is still a lot we don't know, according to Ulf Danielsson, professor of theoretical physics at Uppsala University. Besides doing ...

In Interstellar, Miller’s planet orbits close to the black hole Gargantua, where gravity is so strong that time runs much slower. This is gravitational time dilation, a prediction of Einstein’s ...

What is the purpose of light? How does light work? Why does light exist? This video explores the longstanding debate over ...

The U.S. stock market continues to absorb its knocks, whether geopolitical, credit-linked or trade-induced, and sits at ...

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

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 ...
