The Sun Should Be Cold. It Isn't

[00:00:00]The sun should not be on. It should be cold and dead. To fuse hydrogen the way the sun does, you need temperatures of 10 billion degrees. The sun's core is 15 million degrees. That's a thousand times too cold. And yet, it's been burning for 5 billion years. So, what's the sun doing that we're not seeing? It's cheating. The protons don't need to climb over the repulsion barrier. They tunnel through it. The sun has more protons than you can count. And that adds up to enough energy to light an entire solar system for billions of years. And that's just the sun. There are more places in your life where physics cheats. And the next one is inside every single cell of your body.
