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.

Explain the concept of the Big Rip and its implications for the universe.

What is the Big Crunch and how does it differ from the other scenarios?
