Thread: Quantum entanglement

Please can someone explain this to me as best they can . As I understand it if two subatomic particles have touched they can then affect each other instantaneously even if they are on the other side of the universe from each other. However seeing as during the big bang every single particle was in one tiny space and touched each other that should mean that every particle should affect every other particle ... shouldnt it ?
Also which particular particles are we talking about ? Electrons ? Quarks ? Gauge bosons ? I realise that to a trained physisist my questions must seem fumbling and ammateurish but any help informing me would be much appreciated !

And another thing -
does nonlocality not in effect violate Einsteins law that nothing can travel faster than light ?
