Infinity

[fdesilva]

At the big bang the laws of physics do not exist. That is why its called a singularity. You do not have a before hand as time itself was created at this event. These are the accepted facts, not something I am making up

No, these are not accepted facts. This is just the extent of our understanding.

Science is open to change with new findings and in that sense its not a definite. However the most widely accepted fact is that there was a singularity at the big bang. All of the references you have given, also make this very clear. So it has an origin. In regards to it being cyclic this view is seen to be less viable as the universe has been found to be expanding at an increasing rate which would mean that it will expand to infinity so the energy which is finite ,will get distributed over infinity, making it zero in other words the universe will disappear.
Thus the question of where it came from is valid, as such all your references are also asking that same questions and hypothesizing on how it may have come about. What this thread is about is to say that, if what ever that created this universe has an infinity that is the same as this universe, then it would in turn have a creating event and as such will not qualify as the ultimate origin. The ultimate origin essentially has an infinity that is different to the infinity derived in this universe.
