Science is based on reality, wouldn't you agree?
So if our science demonstrates ALL OVER that there is always a cause, how come you cannot cast this to the beginning?
Our entire "history of the universe" is based on casting current findings to the past. the assumption is that things worked than as they work today. we know there was a change of forces, we know to calculate the movement of the universe, all based on the assumptions that the universe works as it works. why the change? it sounds very much theistic way of thinking the the universe might have just popped into reality
Well, there are many problems with that, especially if we consider the ontology of time we get from relativity, but I would like to keep the discussion focused. I am also a bit selfish, since invoking the ontology of time we get from modern physics would destroy all arguments involving beginnings, causes, ends, etc. And it is not fun to use the nuclear option prematurely and kill the problem from the start.
So, let's adhere to the 18th century view of time. The Newtonian time that flows, leaving the past behind it and where the future is yet to come. The time of our natural developed intuition. In which things can begin to exist in the present without having already been present in the future. The so-called A theory of time. I also concede a predefined arrow that runs (from past into future through present) independently of the contingencies of the Universe. The time that accompanied humanity until Einstein.
Let's concentrate on this version of time. I am afraid you have still to show, even under this premise, that causality chains always reach an end.
My challenge to you is to show me that something like an infinite regress will lead to some sort of contradiction. Remember:
1) Nobody knows what happened at the Big Bang. Some speculate that there was an Universe "before". For instance, sir R. Penrose and S. Carroll. So, nothing is settled there.
2) You can have infinite regressed sequences that unfolds in finite time
So, show it to me. Show me that causality chains will always eventually reach an uncaused cause, otherwise we have a logical contradiction. After you made your case, we will submit it to logical analysis.
