Well the biggest problem with String Theory is that it is basicly upnprovable. Since, according to Bill Bryson’s *, we have never seen an electron, much less a quark, or a neutrino, or a photon or a gravaton, or anyone of the 100 sub-atomic particles that are mathematically postulated to exist, it is really difficult to guess when or if we would ever prove ST since they have not been observed directly.
Let me insert here that the far outer planets as well as pluto’s moon were mathematically postulated before being definitively discovered so lack of imperical observation is not proof of non-existence.
The idea is that everyting…
EVERYTHING is made up of tiny, tiny, tiny, tiny, tiny, tiny strings of energy which vibrate within 7,9,10 or 11 dimensions, which we cannot see because we are not small enough, and the way in which they vibrate determines what kind of sub-atomic particle they will compose. The atrraction of ST is that it irons out the apparent contradictions within Quantum Theory while at the same time still working for Einstein/Newtonian macro-atomic physics.
Is any of this real and what does have to do with God, not much. Except of course that if the contradictins of QT can be ironed out then causality comes right back into the forefront of explaining the universe and randomness (and along with it scientific atheism) goes right out the window.
BTW, a lot of QT physicists really dislike ST or at best will call it irrelavent.
