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

Physicists show knotted cosmic strings may have dominated the early universe before collapsing to create matter—a theory ...

The uncertainty inherent to quantum mechanics has long left physicists wondering whether the observations we make on the ...

A theoretical study suggests that gravity could have quantum effects without itself being a quantum theory. Other researchers aren’t so sure.

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!

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

If we take out all the matter, neutrinos, dark matter, cosmic rays, and radiation from the deepest parts of the voids, the ...

Sorta sparked by this comment someone made to me but it's similar to what other people have told me before: I was listening to a lecture on quantum electrodynamics and it helped me conceptualize the ...

PsiQuantum and Lockheed Martin ($LMT) have signed a new agreement to work together on quantum computing projects for ...

Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether in a physics class, in the lab, or in popular science writing, is left ...
