Brane or Bubble Theory of Universes?

My current research is in M Theory, which seems to balance better, especially in terms of gravity. M Theory is a development of string theory, there being 5 of those, each seeming to be a facet of the others. String theory requires 10 dimensions to make sense, however, by adding one more, M Theory springs up. It appears to amalgamate all 5 string theories into one single theory. The mathematics are beautifully fitted together, though somewhat abstruse for a non-specialist. If M Theory turns out to be broadly correct, it means our Universe began with a collision between 2 'branes. This does away immediately with the "something from nothing" problem, being effectively a "white hole" from the Multiverse into our own. Not only that, but if we assume that gravity is a force of the Multiverse, and shared among all universes, we have an explanation for the comparative weakness of the gravitational force. Richard Feynman's sum-over- histories works even better in M Theory than in standard quantum mechanics, so all-in-all, I suspect M Theory will turn out to be, at least part of the answer, though probably heavily modified. It is true we may never be able to prove it experimentally due to the energies required (probably in the order of all the energy in the Universe), but that doesn't necessarilly invalidate the theory.

Both theories cannot be proven in experiments, but after studying both of them, the M-Theory seems the lesser of the two evils. Through superstring theory, the theory explains the nature of the universe so completely. Even I'm thinking of subscribing to the theory, but unless it can be proven, we can only sit on it.

Quantum mechanics is a proven and tested area, and it almost succeeded in describing the entire nature of the universe...save for the nature of gravity. Quantum mechanics can only explain how gravity works, but not why it works the way it did. String theory did the job, but only in equations and theories. Now...if a new unifying theory could surface, then...

Pros and cons exist for all theories, and none of them are wrong if they cannot be falsified. So, we can even create our own theories and say we're right, as long as no one is able to prove us wrong :-D

I think they are both hog wash. My theory of an expanding toroidal universe makes more sense. Mine even solves the mystery of how light behaves as it does!

extremely tough point. check out over google or bing. that can assist!

Fine, thank you.
