Time feels like the most familiar thing in the world, yet it hides one of physics’ hardest questions: why do we only remember ...

Understand Einstein’s General Relativity with a clear and easy-to-follow explanation that breaks down complex ideas like ...

Fr. Gabriele Gionti, S.J., and Fr. Matteo Galaverni continue to produce new mathematical insights into Albert Einstein’s theory of General Relativity (that treats gravity as a warping of space and ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

The 1919 total solar eclipse provided the first empirical test of Albert Einstein's general theory of relativity, specifically measuring how the Sun distorts light from background stars. General ...

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 ...

Einstein's theory of relativity replaced Newtonian mechanics. Quantum mechanics transformed our understanding again. Today's cutting-edge theory—quantum gravity—suggests that even space and time ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window into the universe’s most extreme events. These collisions not only revealed ...

I don’t want to sound biased about the various Universities, but I think that Ouachita Baptist University is possibly my favorite private school for music and theatre. The sounds that came out of ...

Florian Neukart does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond ...

A new study, based on years of precise data from telescopes such as the Dark Energy Survey in Chile, above, suggests that the mysterious force known as dark energy may be evolving over time rather ...

Astronomers have detected a collision between two black holes in unprecedented detail, offering the clearest view yet into the nature of these cosmic oddities and confirming long-held predictions made ...
