Strings, gravity and dark matter

[Jeebus]

After recently seeing Brian Greene's "Elegant Universe," I was struck by an idea - maybe not an original idea, but an idea nonetheless. If gravity is a weak force because it is not stuck to the "brane" of this universe, then gravity from our universe can influence others and vice versa from distant galaxies, right? If matter is in adjacent universes could that influence ours via gravity(?), it would appear to us that some invisible form of matter, "dark matter", was exhibiting a gravitational effect.

Has anybody investigated this concept further than I?

Yes, there have been many theories and studies exploring the relationship between strings, gravity, and dark matter. Some physicists believe that string theory, which suggests that the fundamental building blocks of the universe are tiny vibrating strings, could potentially explain the nature of gravity and its interactions with other forces. In this theory, gravity is not a separate force, but rather a manifestation of how strings interact with each other.

As for the concept of dark matter being a result of gravity from adjacent universes, this is known as the "brane world scenario" and has been explored in various studies and discussions in the scientific community. However, it is still a highly debated and speculative idea, and there is currently no concrete evidence to support it.

Overall, the relationship between strings, gravity, and dark matter is a complex and ongoing area of research in physics, and there are many different theories and ideas being explored. So while your idea may not be entirely original, it is certainly a valid and interesting concept to consider.
