Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

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 ...

A scientific dispute nearly a century old now appears to be nearing its conclusion, as the results of two new quantum experiments may clarify which of the opposing theories of Einstein and Bohr was ...

In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew. When you purchase through links on our site, we may earn an ...

Quantum entanglement is one of the strangest discoveries in modern physics — a phenomenon where two particles behave as a single object, even across vast distances. Einstein rejected it, calling it ...

There is a long history of doing physics by imagination. Albert Einstein built his special theory of relativity after imagining himself chasing a beam of light. Erwin Schrödinger gave us a cat that ...

A century after Michelson and Morley’s historic zero result helped launch Einstein’s special relativity, physicists are still searching for tiny cracks in one of its core principles: Lorentz ...

The two stars in the nearby system ZTF J2130 are spiraling toward a catastrophic supernova. In the meantime, scientists are using the pair's slow orbital decay to put Einstein's theory of gravity to ...

Black Thought and Questlove believe in the "vison and drive" of newly appointed "Two One Five Entertainment" General Manager Cole Brown. Hip-hop icons and businessmen Questlove and Black Thought ...
