One day, the Universe will go completely dark. No more stars. No more light. Just a cold, endless equilibrium where energy can no longer be extracted.
This is known as the “Heat Death of the Universe.”
What will the universe’s last flicker of energy be? Dr. Ethan Siegel breaks down two possible final acts of the cosmos:
Corpses of stars spiraling into each other, emitting their last gravitational waves.
Supermassive black holes slowly decay over time until the last one releases one final flash of energy that propagates throughout the Universe at the speed of light.
