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

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

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other ...

“The main idea is to have a gravity gauge theory with a symmetry that is similar to the Standard Model symmetries, instead of basing the theory on the very different kind of spacetime symmetry of ...

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

Quantum field theory (QFT) provides a comprehensive framework for describing the fundamental interactions of matter and radiation. In the context of atom‐field interactions, QFT elucidates how atoms ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Advanced quantum spectroscopy at RIKEN reveals insights into antiproton properties, potentially challenging CPT invariance ...

Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

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 ...

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 ...
