Dark matter and branes?

[Daecon]

Would I be correct in presuming that speculation on the idea that dark matter is matter confined to a parallel brane to our Unverse's standard 3 dimensions, has been considered and dismissed?

 

If the other fundamental forces are confined to their native brane but gravity isn't, to explain the undetectable sources of the extra observed gravity supporting the shape of the galaxy?

 

Although I suspect if this were the case, and there was extra matter within the other dimensions, then it could be reasonable to assume it behaves like our matter - and given the right conditions - could potentially form a black hole which would probably manifest in our brane as an unexplainable source of high gravity.

 

Which hasn't been the case.

 

So... uh, I guess I should have put a bit more thought into it before making this post.

People have considered dark matter as the gravitational interaction between another brane close to ours. Remember that gravitons are not confined to branes.

 

For more details you should hunt through the arXiv for brane cosmologies and similar terms. This is not really my field of expertise.
