Mark, interesting that you should raise this.
I was lying awake at 4AM, expecting more phone calls from troubled power stations, and started pondering the ever expanding and accelerating universe.
Why is it accelerating ?
Dark matter ?
And it's allegedly finite.
Then started to think about a moebius strip. Say a (linear) big bang occurred at a point, and energy/matter started heading out away from each other. They grow increasingly distant from the point of origin.
They start heading towards each other on the other side of the strip, essentially on the other side of the universe (although potentially extremely close, around the loop, and they are heading back towards each other, although still away from the point of origin.
Eventually, they start attracting each other through simple gravity, accelerating until they collide again.
Anybody any good at 4D maths ?
