That paper is from 1982. Their theorem is from 2003.
You can evade the theorem, sure enough, but doing so lands you in obvious absurdities.
I don’t depend on this paper at all. I’ve used philosophical argument to already show the singularity. It’s not been refuted yet. Still waiting. I’m going to throw in another argument as well just to spice things up in a little bit.
They try and invoke inflationary/quantum models that either contradict themselves or are purely speculatory. Sub-atomic events are not uncaused. There is no such thing as a free lunch as far as the universe is concerned.
I’m aware of Vilenkin’s model of quantum creation. He tries to avoid the singularity by positing that the universe tunneled to inflation from a radius of zero. His quantum tunneling is from something to something and is not true nothingness, which is what his theory, empirically demonstrated.
He’s trying to find some model to avoid the conclusions of his original theory which is empirically verified. It isn’t working very well. There’s nothing he can do to bridge the gap between uncaused being to non-being. That’s why he has to contradict (without any evidence) his previous theory and say that it wasn’t really ‘nothing’ it was just really, really, really, small.
Can’t be.
You’re post, ironically, is on my side even though you don’t know it. He’s trying to avoid this state of nothingness that he himself empirically verified because he can’t accept uncaused being from non-being.
He won’t accept my alternative, either. I might have all the evidence on my side, but I can’t force someone to adopt the truth. I can’t force them to think. They simply don’t like my alternative, so they posit false models. He’s forced to assume that the laws of physics must have existed.
He’s trying to avoid nothingness so that he can invoke his pet inflation theory.
But of course, the origin of the initial point of Vilenkin’s tunneling diagram remains unexplained. – (in his book, Many Worlds in One: The Search for Other Universes)
