What happens at the end of the universe?

Today, we're bringing you the final installment of our space summer series ... with the end ... of EVERYTHING. Will the universe end in a huge cosmic unraveling? A slow and lonely dissolution? Or a quantum-level transition that breaks the laws of physics? Theoretical astrophysicist Katie Mack breaks down three possible scenarios for how the universe as we know it will finally come to an end.

To celebrate the end of our Space Camp series, we also made a QUIZ! Check it out at npr.org/spacecamp.

The curious case of the supermassive black hole

Black holes are one of the most mysterious cosmological phenomena out there. Astrophysicist Priya Natarajan calls them "the point where all known laws of physics break down."

On the list of perplexing qualities: The origins of supermassive black holes. That story was only confirmed within the last year.
