My belief is that our Universe is potently moving as a single object through the void of the unknown, which is outside our universe. The outside of our Universe is made up of Dark Matter. With this model there was never a big bang but in fact matter is been continually created and slowly makes it way within our Universe until it finally disipates and makes it way back into the void. The reason I feel this is possible is because it exists today, so if our belief is that what has been has always been, that then suggests that there is a continual cycle which goes on and on. A Big Bang suggests there is a beginning and then a end. As now we are aware that the Universe is expanding at greater than the speed of light, so it is unlikely it will ever come back together again, and if the other theory is true it will simply just vanish at some point, if this is true why are we here now. For me a continuous moving universe where matter is always been created and therefore our Universe will continue to be here, but of course it is continually changing. Maybe the only way it could end is if it has a head-on with another Universe travelling in the opposite direction. But that is another idea of mine. I am currectly in the process of writing a paper on this so if anyone aware of any theory that could contradict this idea.
