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 ...

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

On January 22, 2025, physicists unveiled a groundbreaking discovery that could revolutionize our understanding of the ...

The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading candidates for a ...

Physicists are challenging long-held beliefs about time, suggesting it may not be a fundamental aspect of reality but rather ...

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

So darkly complex, so fabulously remote from the familiar things of human existence is science’s probing into the fundamental secretae of the universe—of light, electricity, gravity, matter—that the ...

Imagine a physicist observing a quantum system whose behavior is akin to a coin toss: it could come up heads or tails. They perform the quantum coin toss and see heads. Could they be certain that ...
