how serious is this theory? has it been used to define GR or SR yet or even parts of it? it is exciting, actualy, because as a student of Mathmatics with an intrest in physics, I have come to think that a theory of the universe that allows for mathmatical solutions dealling with infinity are inherently flawed at those points. just like newton's theories were shown to be flawed when maxwell applied them to magnatism and found that they had results that were inconsistent with what was observable, we have seen that GR has the same limitations, where as QM is much more robust. I am confident that when we can explain GR in terms of some form of Quantum effects that we will see that all those infinities are not really there, though the barriors those infinities present are most certainly in existence, they will probably be explainable through a more advanced version of the uncertainty principle.
