Quantum gravity does not allow global symmetries of any type. Quantum gravity requires that any internal gauge symmetry (which implies conservation laws like electric charge, color charge ...

The main idea is to have a gravity gauge theory with a symmetry that is similar to the Standard Model symmetries, instead of ...

To understand this, recall that in the standard model, a different kind of symmetry, 'gauge symmetry', is primary. Gauge symmetry is familiar in classical electromagnetism and in general ...

Their paper, published in Physical Review Letters, specifically proposes that the dynamics of these rotating black holes is constrained by the principle of gauge symmetry, which suggests that some ...

A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler ...

We do not have the answer. Without this critical gauge symmetry associated with electroweak symmetry breaking, existence wouldn't be possible, as we do not have stable, bound states made purely of ...

You call a certain type of symmetry, gauge symmetry, the most important symmetry of nature. What is gauge symmetry? The fact that you have to ask that question is important. There’s been a total ...

These new symmetries, known as “gauge” invariances, became extremely productive, “furnishing the world,” Kaiser said, by requiring the existence of everything from W and Z bosons to gluons. “Because ...
