-So far, M theory doesnt say anything at all about anything that is actually real.......
According to the Princeton researchers, random fluctuations in this unseen companion universe caused it to distort and reach towards our Universe. The floater "splatted" into our Universe and the energy of the collision was transformed into the matter and energy of our Universe in a Big Bang.
According to Professor Sir Martin Rees: "All these ideas about the ultra-early universe highlight the link between cosmos and micro-world - the ideas won't be firmed up until we have a proper understanding of space and time, the 'bedrock' of the physical world."

As the M-theory is no where complete, nor does it have a substantial amount of evidence to prove it, the M-theory says nothing about the universe before the big bang. Actually, we have very little knowledge overall, about the universe before the Big Bang, as there was no Universe before the Big Bang
It says there was, is and will be a 11 dimensional bulk or hyperspace in which membranes with entire universes on their surface exist. Although we are waiting for evidence that suggest M-theory over alternatives, it correctly predicts the sub-atomic particles we have seen to date including the Higgs Boson, so in fact it does have a lot of evidence. It just hasn't been contradicted yet.
So far, M theory doesn't say anything at all about anything that is actually real.
