This may be a sensible question. Or I may be having an ICANT moment. I want to ask about the hypothesis that our universe was created by colliding branes. Also known as the
Ekpyrotic Universe model.
If the universe was created by colliding branes does this not warrant some validity to ICANT’s oft recited and disparagingly dismissed question of What came before T=0?. Now before anyone starts jumping up and down and talking about going North of the North pole etc. etc. Let me just say I know all that. I have no problem with the idea that time as we define it in our universe is itself a feature of the existence of our universe.
What I am asking is the following: If our universe is the product of colliding branes then this implies that there existed something before our universe did. In fact it suggests that there were things (i.e. branes) which were in motion prior to the existence of our universe. And the concept of motion itself implies a change of position in time. So does the colliding branes hypothesis require that there were direct equivalents to time and space in the multi-brane-verse before time and space as we know them as features of our universe existed?
I have placed these terms in "parentheses" to indicate that the terms in question are not the same as those that are products of the observable physical time and space within our universe.
