<Well, the second law of thermodynamics indicates that the universe as a whole will reach a steady state (at a very cold temperature). Is this perfection? It is a case of great symmetry.>
A case of great symmetry. That is an interesting thought, I think I can use that but for now a couple of comments on what my little pee brain thinks might be the end, or as you will see, the beginning.
I have not thought of this much for years, and may not have ever verbalized it so please allow me a little latitude.
Perfection may not be the correct word when applying this to the universe as a whole so I will put it this way. Perfection will be reached when there is no resistance. I think this can only happen when there is only one force. One force in that all energy has coupled and is moving in one direction or towards a single goal.
When this happens then we have only pure energy. Let's call it the original energy, the energy that now drives everything but was once in a pure form.
I think you will know what I mean but let me add this. For every action (energy) there is an opposite and equal reaction (energy going in the opposite direction, resistance). What if there was no resistance, all energy was moving in the same direction.
For this to occur the energy would probably all have to be in the same place at the same time. This brings me to the big bang and black holes of which I know very little but try this out.
The end result of a black hole is when everything (all energy) within reach is sucked into an infinitely small, infinitely dense center. At the infinitely :) short moment that happens you have pure energy and all of it. No resistance. At that same moment all this energy explodes and the process starts over again.
We have an expanding universe ( energy moving in one direction, away from the center) whose original and singular resistance is gravity ( energy pulling in the other direction). Given these two forces all other forms of energy (energy not moving in concert and therefore creating resistance) are created as these forces push and pull on each other.
All that we see today is the result of energy acting in different forms against different resistance and therefore used or processed in different ways. At some point the expansion of the universe caused by the original black hole explosion will stop. The energy will then begin to return and the process will repeat itself.
Now back to the first paragraph. You can see why I would not think the universe could ever reach a steady state. Even if the energy from the explosion, let's say ran out, and all the movement stopped, you would still have gravity pulling it all back together.
Have I stated this well enough that you can make any sense out of it?
