The End of Everything by Katie Mack

Let's read The End of Everything: (Astrophysically Speaking) by Dr. Katie Mack.

We know the universe had a beginning. With the Big Bang, it expanded from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life as we know it. But what happens to the universe at the end of the story? And what does it mean for us now?

This book looks at five ways the universe could end, and the mind-blowing lessons each scenario reveals about the most important concepts in cosmology.
