Ok first post so ill try to make it interesting :)

Here's a new take on an old subject.

Could the space that is ouside the boundery of our Universe have these qualities?

1. Be multi-dimentional
2. Be non-linear

This would mean that at any given point in the space beyond our universe would theoretically contain all space ouside and would be present at any given moment of time.
Also add that this space would not be a vacumn unlike the space we experience in our universe.

And to throw in another thought compare the above to the description of God or any other figurehead used in most religions.

lets call this space X for future referance


On to the next bit :

Lets say at the moment of the big bang there was an event not taken into account, lets say at the moment of the big bang there was a shockwave this shockwave I like to call a time eddy (referred herein as Y) Y preceded the expulsion of the finite amount of matter that we have come to know as Stars, Planets etc. Lets call the finite amount of matter Q
Y has a finite amount of momentum and creates a bubble within X, this bubble is the universe as we know it with Q always trying to fill the bubble that Y creates.
With Y having finite momentum we can say that it will reach its apex at some point, when this happens X not bieng a vacumn will take charge causing the bubble to move back within itself causing Q,X and Y to eventually try and exist in the same point of space time, resulting in another big bang.

Well I'm getting tired so if you want me to expand on any points or anything please let me know :P
