We Finally Know How the Universe Will End (And Begin Again)

For twenty-seven years, we believed the universe would end in ice—a "Heat Death" where stars burn out and space expands forever. But new data from 2025 has changed everything. Dark Energy is weakening. The expansion is slowing down. In this relaxing space documentary for sleep, we explore the terrifying and beautiful reality of the Big Crunch and the Cyclic Universe.

We are living through a pivot point in cosmological history. Based on the latest findings from the Dark Energy Spectroscopic Instrument (DESI) and research from Young-Wook Lee and Henry Tye, we now know that the universe may not be infinite. It has a lifespan.

In this deep sleep narration, we explain how Dark Energy—once thought to be constant—is fading. We map out the timeline of the future: the halt of expansion in 11 billion years, the reversal of gravity, and the eventual collapse of space itself. We visualize the blueshift of distant galaxies, the heating of the Cosmic Microwave Background, and the final moments where physics breaks down.

But the end is not the end. We discuss the Big Bounce, Roger Penrose’s Conformal Cyclic Cosmology, and the theory that our universe is just one breath in an eternal cycle of death and rebirth. Close your eyes, let the anxiety of the day fade, and drift off to the science of the eternal return.
