Did mathematics exist prior to the Big Bang? Quantum field theory says yes.
In fact the Big Bang may have been the result of symmetry breaking.

Symmetry breaking has explained a number of phenomena such as Inflation and the existence of Z and W bosons.

So Steven;
If:
- symmetry under translation corresponds to conservation of momentum and;
- symmetry under rotation to conservation of angular momentum and;
- symmetry in time to conservation of energy, e,

have they figured out which symmetry broken system is thought to have caused the Big Bang ?

Cheers
