Shedding Light on Dark Matter

A thought recently entered my head, for absolutely no reason, and I felt compelled to share it here with you.

While watching a TV show on recent astrophysical breakthroughs, the problem of Dark Matter was brought to my attention.

As you should know, everything with mass has gravity, and since a gravitational pull never disappears, no matter how far away from the object that originally created it, everything in the universe is being pulled around from every direction.

Scientists (those clever bastards!) armed with overly complex instruments, can measure the overall gravitational pull on an object, and as such can measure all the gravity in the universe. EG, they can measure all the mass in the universe.

Some clever person made the calculations, and realized, to some annoyance we might imagine, that the amount of mass the universe was way over the amount of stuff there is. Dark Matter is all that stuff that is evident in equations, but cannot be found or even conceived of what it truly is.

So here's my thought: If the Dark Matter cannot be found within our own 3 physical dimensions, why not look towards a higher dimension? It is sometimes theorized that there are more then the dimensions we can comprehend out there, (11 or 12 are the usual numbers thrown about) but that for some reason they are sort of disconnected from our 3. Perhaps they are simply beyond our level of mentality, or maybe they are shriveled up in a teeny little spot in space and time. Whatever the explanation, these other dimensions are beyond human thought or sight.

So, if we cannot comprehend these dimensions, why can't there be matter within these dimensions, that we therefor cannot comprehend either? All the matter we can see or know of is within our 3 dimensions, so it's not unreasonable to suggest that there is likewise matter contained in the higher dimensions, which cannot be seen, but can be felt.

Who knows what strange stuff might be just beyond our comprehension?
