Why has our universe after 18 billion years not collapsed yet and has degenerated
into higher forms of entropy such as heat ? An answer is that there are hindrances
in our universe that delay the degeneration of energy. One of them is space. The
huge size of our universe hinders this collapse simply because the process takes
such a long time.
Another reason is the circle. In that the earth rotates around the sun at 18 miles per
second it is stable with respect to the influence of the gravity of the sun which would
invariably attract and burn it.
All this hindrances have something in common - they won’t last forever.
This system regulates the cosmic flow of energy and must be regulated exactly for our survival.
There we see a remarkably exact balance.
