The universe stops expanding and collapses in reverse, crushing galaxies, stars, and planets into a singularity.

1. Big Crunch

(Image: AI Generated)

Expansion continues forever, causing galaxies to drift apart, and all stars burn out, leaving a dark, cold universe.

2. Big Freeze

Dark energy accelerates expansion to the point where atoms and galaxies are torn apart.

3. Big Rip

The universe reaches maximum entropy, with no energy left for any processes, leaving an inert, lifeless cosmos.

4. Heat Death

A quantum event triggers a bubble of lower energy vacuum, destroying everything it touches at the speed of light.

5. Vacuum Decay

Our universe collides with another universe, obliterating everything in a cosmic clash.

6. Multiverse Collision

Only black holes remain, consuming everything, until they evaporate into nothingness via Hawking radiation.

7. Black Hole Era

The universe exists in a temporary state and could suddenly “snap” to a more stable, catastrophic form.

8. False Vacuum Theory

If time reverses, the universe rewinds, causing unpredictable outcomes that could end life as we know it.

9. Entropy Reversal

If dark energy reverses its effects, the universe might implode under its own gravity, leading to cosmic collapse.
