How ‘heat death’ will destroy the universe

- The expansion of the universe is accelerating as the force of dark energy wins out over the pull of all the universe’s collective gravity.
- As every object in space moves farther and farther away from all other objects in space, the universe will reach a state of maximum entropy, and ‘heat death’ will ensue. As astrophysicist Dr. Katie Mack points out, heat death is not actually a hot phenomenon—it’s also known as the “Big Freeze.”
- Around 100 billion years from now, the universe will have expanded so much that distant galaxies won’t be visible from Earth, even with high-powered telescopes. Stars will disappear in a trillion years and new stars will no longer form. The “good’ news is that humans probably won’t be around to witness the machine as it breaks down and dies.
