It’s time we talked about loop quantum gravity. What exactly is it? What are the loops? And can it really defeat string theory in our quest for a Theory of Everything? PBS Space Time is available to ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...

Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales Schrodinger’s skinniest kittens Must the Schrodinger’s Cat be fat enough ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well ...

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ongoing quest for quantum gravity. These findings, which involve the behavior ...

Quantum theory and general relativity will only be unified when theory meets experiment Physics in the 20th century was built on two great revolutions: the general theory of relativity and quantum ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

AS THE bell rings for the final round, both fighters are in their corners. The heavyweight champion is panting, against the ropes. The underdog is sprawled on the opposite side, bruised, tired but ...

A team of scientists from the University of Vermont and the University of Waterloo in Canada has discovered that black holes and cold helium atoms have something in common: a law that controls their ...

Two leading candidates for a “theory of everything,” long thought to be incompatible, may be two sides of the same coin. Explore the deepest mysteries at the frontier of fundamental physics, and the ...
