The document discusses the future of the universe according to scientific theories, including that it could expand indefinitely leading to a "Big Freeze", collapse back on itself in a "Big Crunch", or experience repeated expansion and contraction in a "Big Bounce". It also explains that the universe started with a Big Bang approximately 14 billion years ago and has been expanding ever since, as evidenced by the red shift.
Future of the universe
- 1. FUTURE OF THE UNIVERSE What role does science play in explaining the future of the universe?
- 2. THE PAST The universe started with a big bang. From a point of singularity where all matter that exists was the universe expanded over a period of approximately 14 billion years
- 3. THE PRESENT The universe is currently expanding and evidence for this expansion is the red shift
- 4. THE FUTURE Open universe Closed universe Flat universe
- 5. THEORIES ABOUT THE END OF THE UNIVERSE Big Freeze or heat death Big Bounce According to this theory, the universe will one day stop expanding. The big bounce theory combines the big bang and big crunch theories to Then, as gravity pulls on the matter, the create a vision of an endless, in universe will begin to contract, falling which the universe repeatedly inward until it has collapsed back into a expands from a singularity only to super-hot, super-dense singularity eventually collapse back in on itself
