Even if branes exist on spacetime as opposed to in it then it still would have to exist before the Big Bang. Though
that would not necessarily be true if there are other models so maybe it is too early to say at this point in time ?

Dark energy certainly has the properties of repulsive gravity but does that automatically mean
that is what it is ? There must be alternative explanations otherwise why not regard it as such ?

If light is impervious to branes then it is entirely possible
for dark matter to be a result of brane collision is it not ?
