Three ways the universe could end.

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.

Answer the following questions:

1. Why is the general consensus among scientists that the universe started with a big bang?

2. How do scientists predict the possible scenarios for the end of the universe?

3. What is the role of gravity in the evolution of the universe?
