There are no cosmological models which do not honor the initial state. Every single cosmological model whether it is cyclical or not, honors the condition whereby ~14 billion years ago, all matter and energy in the universe occupied the space of 1 billionth of 1 trillionth the size of a single atom and then began to expand and cool.
True or false?
We don't know, Ding. As I said, perhaps the universe is just a mirror image of itself. Which, btw, renders the notion that the universe will just expand and die incorrect.
The very same math that dictates expansion also works backward perfectly. All you have to know is the number pattern.
This is actually what I wanted to explain in your other threrad where you and Ed were debating, but you didn't want it written mathematically. But it's the only way it can be done.
So. Ding, you're running on a theory that depends upon a big bang to be true and without contestation. Without a big bang, the entire theory that the universe is just going to expand until it heats up and dies becomes moot.
The nature of the universe is bi-directional, we can add backward just the same as we can resolve expansion mathematically. Every single law of physics tells us that the universe is naturaly bi-directional.
It is logical to conclude the 2nd functions in the same way. As I said, the math itself works backward.
That's going to sting, Ding, but it's just true.
