- Did spacetime start with the Big bang? 5 answers
I am comfortable with the idea that 'pure energy' cannot be observed, only different forms in which it manifests. I can also understand that matter-antimatter interactions result in fundamental particles that ultimately conserve energy. So forgive my amateur question, but is there any conception of what energy was like prior to the big bang?
It implicitly seems that it would still have existed as particles of some kind, but my understanding is there would have been no space for them to exist in. That leaves me in a position where it seems that it might have just been energy in a state that perhaps can't be observed in our universe, which seems eerily similar to the idea of what 'pure energy' might be. Is it conceived to have been in some undefinable state, or did it exist in a way similar to how it manifests in our observable universe?
