Liability of the Theory that the law of Angular Momentum disproves Big bang.

This may be a little off topic, but it is definately very much related to the question so needs saying.In what way can the universe as a whole be said to have any angular momentum? Motion is relative, so what could the universe be said to be spinning relative to? For the objects within the universe it is impossible to define a single frame of reference where everything is static with no spin, so we can definately say objects within the universe have angular momentum. But with the universe, as far as we're aware there is nothing else.Of course this is totally irrespective of the fact that even if the universe DOES have angular momentum, that wouldn't in any way stop individual objects from having angular momentum of any value and direction, as long as the total spin of all objects adds up to the right value.

What could be more simple than a singularity? Spacetime compressed infintely small, without any matter existing. Simply energy. Even after the big bang there would be nothing more than energy. I can't imagine a state the universe could be in that is simpler than spacetime containing formless energy. Only as the energy cooled did any type of structure start appearing as the energy condensed into matter in the form of subatomic particles.
