Universe’s Expanding Fate: The Big Rip
- The universe's expansion is driven by dark energy, which accelerates space stretching even as gravity thins out.
- This expansion could eventually rip galaxies, solar systems, planets, molecules, atoms, and even space itself apart in a "Big Rip."
Humans Are Cosmic Anomalies
- Dark matter, or "dark gravity," comprises most of the universe's matter but barely interacts with normal matter.
- We, made of ordinary matter, are rare anomalies floating on the ocean of dark matter and dark energy.
Universe Expansion Is One-Way
- Past theories posited a cyclical universe that might collapse and then expand again, inspired by Einstein's equations.
- Recent data show the universe is expanding on a one-way trip, making a future collapse unlikely.
