We know about our universe’s past: the Big Bang theory predicts that all matter, time and space began about 14 billion years ago. And we know about the present: scientists’ observations of galaxies tell us that the universe is expanding at an accelerated rate. But what about the future? Do we know how our universe is going to end? Venus Keus explores cosmologists’ three possible scenarios.
