I don't know what "empirical evidence" you are looking for regarding time. I haven't seen you present any empirical evidence that time is a physical property of matter, so it seems odd you would ask this of me. Time dilation doesn't seem to show anything except that time and space are closely related. In a universe without matter, I'm inclined to believe time would still exist. It may still be that time is nothing more than a concept. Your response in post 113 made me think that this point was obvious to you, and yet you've gone on to insist that time is a physical property of matter. I think this link does a good job of explaining time.
What Is Time? One Physicist Hunts for the Ultimate Theory | Wired Science | Wired.com
Well, first I am not claiming that time is a physical property of matter, but is a physical property of our universe. Although there are some recent rumblings that perhaps 4D space-time is not the best way to descibe reality, there is no widely accepted theory to support this supposition as of yet (at least not that I know of). According to the current accepted understanding of Big Bang Theory all matter, energy, AND 4D space-time were part of the singularity. Hence, the Big Bang did not explode INTO EXISTING SPACE-TIME, but space-time ITSELF expanded. By suggesting that time exists outside our universe, you were implying that space-time existed outside of the Big Bang singularity (whether you admit it, or even realize it, or not), therefore implying that there is indeed something beyond our current expanding universe. The theory of relativity shows that space-time has physical properties as these properties change in gravity and under acceleration, and quantum mechanics also reveals physical properties of space-time with quantum fluctuations producing matter... this strongly suggests that space-time is "something". The existence of space-time outside the Big Bang singularity would make the whole idea of the Big Bang singularity as the uncaused cause of "everything" bunk. Now it seems that you are moving towards the multi-verse theory, which is really more of an idea at this point than a hard scientific theory (even the physicist in your link said as much). Which is it?
Loop quantum gravity theory still has a way to go before it replaces the big bang.
Very true. It is still far from being accepted as the Big Bang is currently.
I understand your point that there is no proof for infinite regress of time for a singularity, but we do have evidence of singularities, we have no proof of god. If I have to choose between two possibilities, an eternal being without proof of existence or an eternal singularity (and there is evidence singularities exist) then its a bit silly to suggest the two options are equally likely.
We have evidence of singularities in space-time... but the Big Bang singularity supposedly was composed of all space-time, matter, and energy. A singularity without space-time to occur in has absolutely no precedent. There is evidence of God, just not evidence you will accept.
WHen I referred to logic and reason I meant that any information should be viewed under the scrutiny of logic and reason before decided the reality of that information. LOL I hope that clears things up.
Your logic and reason is limited by the human condition (timebound, finite, biased, etc). I am quite sure that you will admit that your logic and reason is fallable... and so is everyones (including mine). I am not saying abandon logic and reason, I am asking you to recognize their limitations.
