@vectorcube,
We may not be able to understand the dynamics around eternity and infinity, but we are very capable of understanding thermodynamics, and the first of thermodynamics clearly proves that 'energy can neither be created nor destroyed. It can only change forms.In any process in an isolated system, the total energy remains the same.
Our problem in these suppositions is that we are trying to go from the known to the unknown without any ability to do so or really without any reason.
The physics we know.
Basically stated, if the universe has existed for as long as we seem to think it has, it should have burned itself out a long time ago. That is the pure logic of the physics we know. So according to the laws of physics that we try to write our existence around, the universe cannot be eternal if it is bound to those laws.
However if it is not bound to those laws that we prove mathematically and deem to be non negotiable, than it steps out of the bounds of reality as we define it by our mathematical logic and ability to comprehend.
We have two conflicting truths here.
1. The universe cannot be eternal because it would have already burned out by now. The fact that it has not burned out yet suggests that it is not eternal and had a beginning and will have an end.
2. If it had a beginning, than this suggests a point in time when there was some thing that began from no thing, and this seeming impossible to conceive suggests some sort of infinity or eternity to the universe.
Infinity or thermodynamics. Both cancel each other out. One we know to be actual physics supported by mathematical evaluation minus the final summation. The other we know to be simple logic based upon reason.
Reason versus math.
To accomplish a truce between these conflicts we must go to the source of the conflict. That source once again takes us to that one and only matter that always arises during these processes of comprehension of existence. It is the tool with which we do our reasoning and perform our mathematical tasks. The brain. The problem arises when our brain is trying to tell us one thing and our logic is trying to tell us something else, 'that' is the mind at work against the brain.
Hense the problem is not really one of infinity versus thermodynamics, it is actually one of mind versus brain.
Comprehension of these complex paradoxes is not a matter of discerning the truth in them. That actual truth is out there, left far behind or looming somewhere ahead, and we will not change it by any of our hypothesizing. The comprehension of these dilemmas is simply found in our understanding that our capability is not limited to what the brain is telling us, and that we can also find truth in our logic. When the two collide, we know simply that truth is elusive, and yet there.
The truth of the allegorical caves of Plato reveal that what we are trying desperately to do here is understand with the brain, and all we are seeing is the shadow on the wall.
The truth is out there around the corner creating that shadow, and we are simply not able to be free of the chains that bind us and restrict us from getting there to see what that actuality really is.
In fact what we are doing here is sitting together in chains twisting and thrashing about, arguing about what might be out there, when we are totally disabled from discovering that. Our brain is incapable of revealing that to us without seeing it.
Our minds however are the variable here. Some of us chained in this room do not question the shadows reality and simply accept that the shadow is the reality. Their brain is telling them that what they see is the reality of the moment. In the world of biology and science, what the brain says is absolute and acceptable. What ya see is what ya get. But some others reach deeper than the brain function to find a mind that argues the brains accusations, and they consider other possibilities. The mind will at some point discover what the brain was unable to do. It will seek out the source of the shadows because it was not bound by the biological function and recognized a function that is not located in physiology.
It is the mind that leads us to ponder the origin, the brain that keeps us from comprehending it. But like the true cause of Plato shadows, our origin is outside of the cave waiting to be revealed.
The dilemma of first cause and eternity is not a matter of physics and human brain function, it is a matter of time; not into the past of what must have happened, but into the future of what will be revealed of the truth of what happened.
To shorten this entire post into one thought:
What matters is not behind us but what we are walking into. Will we use our minds to uncover that trail, or walk blindly using our brain and its limited sensory dependencies.
