Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

The Princeton that Albert Einstein knew in 1933 was sharply divided by the color line; a long-established border—marked by ...

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 ...

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 ...

The e-discovery company also moved to open up its gen AI aiR suite to user customization, and integrate with more data sources. E-discovery company Relativity announced Wednesday the upcoming launch ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

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 ...

A research team proposes utilizing numerical relativity, a computational technique for solving Einstein's equations in high-gravity environments, to investigate the universe's origin. The approach ...

Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...
