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 ...

Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the ...

The ability to study graviton-like particles in the lab could help fill critical gaps between quantum mechanics and Einstein’s theories of relativity, solving a major dilemma in physics and expanding ...

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept ...

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

The original version of this story appeared in Quanta Magazine. When it comes to understanding the fabric of the universe, most of what scientists think exists is consigned to a dark, murky domain.

Scientists announced that they have discovered the existence of a particle of nature. There is a wealth of speculations springing from this new finding – could it be, for instance, that this new ...

Quantum gravity tries to combine Einstein’s general theory of relativity with quantum mechanics. Quantum corrections to classical gravity are visualized as loop diagrams, as the one shown here in ...

The accepted theory that the universe began evolving some 13.7 billion years ago from an infinitely dense and hot substance that has been expanding since the first extremely small fraction of a second ...
