I have one of Kaku's books and have caught him on a fair number of science programs, and I quite positive that you don't understand what he actually says. BTW, you can't add infinity onto infinity because just one "infinity" never ends.
Singularity doesn't in any way discount M-Theory or String-Theory, or the possibility of both there being a multiverse and/or possibly parallel universes, all of which Kaku states are hypothetically possible.
Also, this doesn't make sense, so maybe you can try and clarify: "As soon as a secondary is allowed....infinity is simultaneous." What are you trying to say here?
BTW, Kaku is not a theist (he's agnostic), so I think you'rte barking up the wrong tree.
Edited: on the 2nd line of my response, I accidentally wrote the word "can" whereas it should have been "can't".
