@man_ia_c: What if neutrons disappeared for 5 seconds? You're in Central Park at sunset when every neutron on Earth vanishes. Everything loses half its mass: you suddenly weigh as much as a 5-year-old. But neutrons are what hold every nucleus together. Without them, every atom except hydrogen flies apart. The ground cracks open, each person becomes a 7-megaton bomb, and Earth explodes at 27,000 miles per second. Then the neutrons come back to a world that isn't there anymore… and turn into hydrogen. Which one next? 👇 #whatif #pov #simulation #Science #physics
