Russian The greatest minds are pondering the eternal again — and it might not be so eternal after all.
Big Crunch: Collapse Instead of Infinity
One recent theory suggests that if dark energy proves unstable, the Universe won't expand forever.
Instead, in about 33 billion years, it could reverse course, collapsing in on itself — the so-called "Big Crunch." Think slow-motion apocalypse.
Big Freeze: The Slowest, Coldest Ending
In this scenario, expansion never stops. Stars burn out, matter decays, and eventually even black holes vanish. Nothing remains but empty space — cosmic credits roll in pure arthouse style.
Big Rip: The Universe Torn Apart
If dark energy accelerates instead of staying steady, it could literally tear the cosmos apart: first galaxies, then planets, then even atoms. Expansion on steroids.
Big Bounce: An Infinite Cosmic Reboot
Optimists prefer this one: the Universe collapses, but instead of dying, it triggers another Big Bang — a cosmic reboot on endless repeat. Maybe we’re already in one of many cycles.
Vacuum Decay: The Instant Game Over
High-level physics mode: if our universe exists in a "false vacuum," a random quantum fluctuation could rewrite the laws of physics in an instant. No pain. No warning. Just… gone.
Boltzmann Brain: The Weirdest Possibility
Not exactly an ending, but unsettling: in an infinite Universe, random fluctuations could eventually create a single conscious brain that only thinks it’s you. Hello, cosmic solipsism.
So, if you're procrastinating, keep in mind: "later" might end in one of six cosmic apocalypses.
But hey — we've still got billions of years. Time for coffee and the comforting illusion of control.
