In A Nutshell When two different types of cosmic strings become linked in the early universe, they form stable knots that ...

From Fundamental Concepts to Dynamical Mechanisms, by Wolfgang Bietenholz and Uwe-Jens Wiese, Cambridge University Press.

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

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

The poet Blake wrote that you can see a world in a grain of sand. But even better, you can see a universe in an atom!

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 ...

Mean-field theory and semiclassical methods constitute vital frameworks in contemporary quantum mechanics. By replacing the intricate web of particle interactions with an average or “mean” field, mean ...

A new theory suggests that the unification between quantum physics and general relativity has eluded scientists for 100 years because huge "fluctuations" in space and time mean that gravity won't play ...

A new hypothesis known as the Quantum Memory Matrix (QMM) could help explain some of the biggest mysteries of the universe, including the Black Hole Information Paradox. The idea is that space-time ...

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