It's more than that Phemox.

Yes it's complex and you are right, there are plenty of complex theories out there. The problem is that it's complex and (so far) UNTESTABLE. Hence, it becomes an exercise in mathematcal wordplay which may be beautiful and may seem true to the theorists but science does not hinge on mathematics (it doesn't!)... it hinges on experiments.

So without experiments that can test 11 dimensions vs. 22 vs. 54843, the theory is complex and, well, useless. The day we can test this theory is the day that it will become more valid in the eyes of scientists... but heck, we are BARELY now starting to test for the Higgs Particle, a lynchpin of the Standard Model of Particle Physics that has been around for nearly 50 years, so I have no illusions that we will be able to test SS theory any time soon.
