- June 15, 2020
What Happens After the Universe Ends? is the 21st episode of the 2020 season of PBS Space Time. In this episode, the host explores what could happen to the universe after it comes to an end. He first examines the different ways in which the universe could end, from the heat death to the big rip to the big crunch. He then explains how these scenarios would impact the universe's final state.
The host goes on to explain that even after the universe "ends," there will still be particles floating around. These particles will interact with each other, forming new structures. The host delves into the concept of entropy and how it relates to the creation of new structures in the post-universe world.
The host then discusses the possibility of a cyclical universe, where the universe goes through an infinite cycle of expansion and contraction. In this scenario, the universe doesn't truly end, but rather resets itself and begins anew. He explains the scientific theories and evidence that support this idea.
Next, the host explores the concept of the multiverse and how it could impact the end of our universe. If there are multiple universes, there could be a "reset button" that triggers the creation of a new universe once ours ends.
The host also addresses the possibility of an eternal universe where the universe never truly ends. He delves into the theoretical physics behind this concept and explains how it could be possible.
Finally, the host ponders the philosophical implications of the end of the universe and what it means for our place in the grand scheme of things. He encourages viewers to consider the implications of the end of the universe and what it means for our existence.
Overall, What Happens After the Universe Ends? is a thought-provoking and informative episode that encourages viewers to contemplate the possibilities of what could happen after the end of the universe.
