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 ...

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ...

In search of a united scientific theory, a new quantum gravity paper might have proposed an interesting aspect that made the ...

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

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

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

Physicists have demonstrated with unprecedented accuracy that the speed of light remains constant. In 1887, a landmark physics experiment was carried out by American researchers 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 ...

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.

Physicists tested light speed using cosmic gamma-ray bursts. Study confirms Einstein's prediction that all light colors travel at same speed.

Encouraged by successes in understanding black holes, theoretical physicists are applying what they’ve learned to whole ...
