According to two physicists (from Cambridge and Princeton universities), there is neither a beginning nor an end of time. They say the current model of the universe is flawed.

That model starts with the beginning of time and the so-called Big Bang. The universe then cools and expands, and then in the distant future it will cool to the point when no stars are formed and normal matter breaks down. But the expansion is speeding up, and the current model does not seem to adequately explain why this is happening.

The scientists claim their new model can account for this and other things that are difficult to explain. They say the universe is undergoing an endless series of Big Bangs, expansions, contractions and big crunches. There is no end of time and no need to define what existed before the universe was born.
