The Theory of Nothing
The Theory of Nothing begins with the premise that there is nothing to start with. Begin with a universe of nothing but space. This space has no energy and therefore no time. It is absolute zero in temperature, and that qualifies it as a Bose-Einstein Condensate (BCE).
The uncertainty principal dictates that somewhere in this space there is less space than somewhere else. Space without energy (BEC) acts strangely, it has no resistance to movement (superconducting) and all of it acts together as a whole. If there is less space, more space moves to fill it.
When space moves it becomes space-time. Big Bang Theorists tell us that space moved faster than the speed of light during cosmic inflation. This was an unfathomably large amount of energy in an unbelievably small amount of space in an extremely short time. Supposedly, the Big Bang was a one time event 13.7 billion years ago which created our Universe. There is a different possibility.
As it tries to equalize spatial density, space moves, and because space is curved due to this imbalance in density, it begins to move in a curved trajectory. As denser space moves in to fill the void of lesser space, the void shrinks until it becomes the size of the Plank length with a Schwarzschild radius. The incoming moving space circling around the tiny void at the speed of light causes an impenetrable time barrier from the rest of the universe.
The existence of this new imbalance to the density of space causes more of the same, until all of space is filled with diminutive voids surrounded by moving space, attempting to fill the voids but unable to do so due to curved space and time.
Thus spinning space around a void becomes the Universe's hardest, most impenetrable objects. These are the building blocks of all other things, repeating the pattern at larger and larger scales until we find ourselves and our universe as we see it today.
Now we can see that there is no need for a big bang, space by it's very nature will create a universe by itself. This does not rule out a big bang, or series of bangs, they happen constantly as space evolves into higher and higher dimensions, which explains black holes and supernovae.
