Given that the further away a star is from us the further back in time our view of it is. How is this taken into account when calculating the rate of expiation of the universe? In other words, could the fact that the further away a star is the faster it seems to be moving away from us not be due to it not having slowed as much as closer stars, which from our point of view have had more time to do so?

If before the big bang, the universe was a singularity: a hot, dense and symmetrical state.  Then after the universes' 'bang' it disbands in all directions, to fundamentally lose this energy and become an infinite wilderness of low energy and complete disordered state.  Could this low entropic state not have a sense of unique symmetrical order, i.e. a highly order state?  Could this provide a state / catalyst to reverse the expansion direction, to ultimately reform the initial singularity?   

If the universe started out with a random distribution of matter and anti-matter, after they annhilate each other there would be some patches of matter and some of anti-matter left over. Then when the universe expands they would get seperated spatially from each other, allowing both forms of matter to remain in the universe.

Is this a possible scenario? Could there actually be anti-matter galaxies or galaxy clusters out there?

If all the stars are orbiting a super-massive black hole at the centre, why are they only orbiting in roughly one plane? Granted that once they have momentum in that plane the centripetal force of gravity should tend to keep them in that plane, but after the big bang what force caused them to form in that shape?

Considering we have mapped the relative speeds and positions of thousands of galaxies, and so know how fast they are moving and where to, has anyone tried and run the whole process in reverse to see where they all originated from?

This should be ground zero for the big bang (if all matter originated in a point) and would be some evidence for the theory that all matter originated from a single point.

if this point exists, what would be there? Would there be galaxies and stars closer to the point or would that area of the universe be empty of all matter (it having all been propelled out by the big bang)?

There are many predictions made by scientists about the fate of the universe. One of them is the "Big Rip". So the question is, what will happen after the "Big Rip"?

So here's what I think will happen, feel free to correct me if I'm wrong.

1. The universe is expanding and it has been known and proven. If it continues at this rate, every matter inside the universe will be ripped apart.

2. But when the universe reaches it's "elastic limit" and can go no further, it will collapse with great force back into the centre of the universe.

3. When this happens, everything in the universe will shrink back into the size of an electron(or maybe even smaller) with an "infinite" amount of density. This can soon turn into another "Big Bang".

4. And therefore the steps repeat itself when there is another Big Bang.

Example: Imagine a coil of spring. If you compress it very tightly, it will repel back at you with great force. If it is pulled very strongly, it will pull itself back to it's normal shape with great force.

I believe that the universe is like a spring, but the only thing is that it doesn't have any definite shape.

Scientists said that the Big Bang was caused by the conversion of energy into mass, according to Einstein's E=mc2 formula. But where does this energy come from? And what actually triggered the Big Bang?

Ok, we all know the speed of light (well actually I don't but I know I can google it) but the big question in my mind is the one no one seems to be asking. We are all focused on understanding the creation of the universe when in fact we ought to be asking ourselves what exactly our universe is existing in.

My current theory is that the universe is expanding into time and, using that logice, I must exists many times over, just with billions of years between each existence. Am I right about this???
