M-theory… does it explain dark matter/energy?
Hi, first, I’m not a scientist… you could call me a cosmology cheerleader or something like that… I watch anything about cosmology, physics and space/time that I can find. If it has Michio Kaku (mkaku.org) then I’ve seen it.
Anyway… I caught a documentary last night on sci channel called Parallel Universe…. it was really a mind opener…
It was great to see a proposed timescale that goes back beyond the initial singularity of our universe… it’s about time 
Also, the weakness of gravity and ideas about how the gravity that we detect is leaked from other “branes” made a lot of sense to me… It also made me ask…
Is our universe’s dark matter and energy an effect of another brane which is currently undetectable from the brane in which we perceive our universe? Also, if so, is this why we detect a matter deficit in our universe?
Perhaps the matter that we know as dark matter doesn’t reside in our brane at all.
