Imagine this: the universe as we know it could be living its final moments. But what if I told you there was more than one way this could happen? Let s unravel the dark mysteries of the end of the universe. The universe began more than 13 8 billion years ago with an explosion the Big Bang. Since then everything has expanded and this expansion not only continues but accelerates. Something scientists didn t expect. And everything points to a very different future than the one we know Imagine a cold dark empty future. The Big Freeze tells us that if the expansion continues to accelerate in a few billion years the stars will exhaust their energy. Galaxies will move so far away that the light from other stars will never reach us. The darkness will be absolute. The universe will become a frozen desert.
