Why is this ideal "almost as absurd as goddidit"? If branes are physical entities embedded in an appropriate space-time, then motion thereof within that spacetime, and collisions between said entities, is no more problematic than that of snooker balls.

My understanding is that the postulate currently regarded as applicable, is that they have existed right back into the infinite eternal past.

See the two papers by Steinhardt & Turok I've presented in the past, which contain the details.
