Big rip pays big bang debt

The universe is expanding at a rapidly increasing rate. Some scientists believe that in about 50 billion years the speed of expansion will be so great that the universe will tear itself apart.

As the speed of the expansion reaches the speed of light, further acceleration may send it back in time, perhaps to the beginning of the universe.

At that point there may be a big bang or the start of our universe. Our universe creates itself. Nothing for free and all debts paid.
