TED-Ed: Three ways the universe could end - Venus Keus

The video explores the universe's past, present, and potential future. It discusses the Big Bang theory and the current accelerated expansion of the universe. Three possible scenarios for the universe's end are presented: the Big Freeze, where the universe becomes cold and dark; the Big Rip, where all matter is torn apart; and the Big Crunch, where the universe collapses back into a dense state. The Big Bounce theory suggests a cyclical universe. Current observations indicate a likely Big Freeze, but this is far in the future.

What does the Big Bang theory suggest about the universe's beginning?

• The universe started from a large, diffuse state.

• The universe has always existed in its current form.

• The universe was created by a collision of galaxies.

• The universe began from a tiny, compact state.

In the Big Freeze scenario, what happens to galaxies over time?

• They merge into a single massive galaxy.

• They dissolve into isolated objects.

• They remain unchanged.

• They form new stars continuously.

What is the Big Rip scenario characterized by?

• The universe remaining static.

• The tearing apart of galaxies and even atoms.

• The universe contracting into a dense state.

• Galaxies merging into clusters.

What does the Big Crunch scenario involve?

• The universe expanding indefinitely.

• Galaxies moving away from each other.

• The universe remaining in a frozen state.

• The universe collapsing into a dense, hot state.

What is the current scientific consensus on the universe's fate?

• The universe will experience a Big Rip shortly.

• The universe will undergo a Big Crunch soon.

• The universe is likely headed for a Big Freeze.

• The universe will remain unchanged forever.
