Hawking On The Edge Of The Universe
In the text, "Perspectives of Non-Linear Dynamics", the author asks,
"what happens to a fly, a corporation stock, a star, or a civilization when respectively a venus flytrap closes, there is a stock market crash, it becomes supernova, or a nuclear war breaks out?"
Singular points are reached in these cases (I believe) and the descriptions for the fly, markets, civilizations, and stars cannot (in some ways) be used to adequately describe the dynamics of the phenomena past these singular points.
I bet that's the way it is with the Universe as a whole. Some qualitative extension of our current understanding will be required to further our understanding of it in the same way the qualitatively different "round earth" was used to answer the question of what happens if we keep walking in a straight line.
Just my opinion. :)

I am talking strictly cosmology, I got the impression you were calling singularities in cosmology critical points.
In short I believe if there is a supreme intelligence then he is a scientist, as such everything we see should be explainable by physics. I am excited to be alive and studying cosmology, I have this crazy dream that maybe years down the road I can contribute, and if I cannot master the math then I'll leave it up to my children whom I am trying to brainwash into becoming cosmologists lol.
I respect your outlook though and I am by no means saying you are wrong, the plain truth is none of us here can say for sure... it may be that infinities are a crucial part of this universe being here and have no explanation.. but I like to think we can figure it out in due time.

No physicist holds that the singularity actually exists it's just an ideal mathematical limit to a series in a sense of calculus.

In Hawking's model time becomes another dimension of space, it is spatialized.
