PhysicsOverflow is a next-generation academic platform for physicists and astronomers, including a community peer review system and a postgraduate-level discussion forum analogous to MathOverflow.

Welcome to PhysicsOverflow! PhysicsOverflow is an open platform for community peer review and graduate-level Physics discussion.

Please help promote PhysicsOverflow ads elsewhere if you like it.


PO is now at the Physics Department of Bielefeld University!

New printer friendly PO pages!

Migration to Bielefeld University was successful!

Recent questions tagged beyond-the-standard-model

Use this tag for questions beyond the standard laws of physics (General Relativity and the Standard Model) if a more specific tag, like string-theory, loop-quantum-gravity, supersymmetry, etc. do not apply.

Beyond the Standard Model (BSM) physics has often been criticised as "speculative", but it is generally accepted that the Standard Model cannot be a theory-of-everything as it does not incorporate gravity, etc. Other reasons why BSM physics is required include:

  • The Standard Model is perturbatively done.
  • The Standard Model has a large number of free parameters.
  • The Standard Model is a man-made theory, which means it was constructed to match experimental data. It has thus, little predictive power compared to a theory-of-everything.
  • The Standard Model does not describe gravity.
