For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.
Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...
A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the ...
A study by physicists affiliated with the Foundational Questions Institute (FQxI) found that time ...
Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...
Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...
Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a ...
