In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley ...

Several leading quantum gravity theories predict that there is a dependence of the speed of light on photon energy, which would bridge ...

Albert Einstein changed science forever with special and general relativity, redefining space, time, and gravity. Yet after his greatest triumphs, he became obsessed with something even bigger — a ...

Several leading quantum gravity theories predict that there is a dependence of the speed of light on photon energy, which would bridge incompatibilities between general relativity and quantum physics.

A hundred years ago, a young physics teacher in Calcutta quietly rewrote the way nature counts. On November 20, the idea he ...

The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

Quantum oscillations are typically found in metals, but finding this same “electron wiggle” within the bulk of insulators is ...
