Скачать или смотреть Feynman Explains Why the Sun Isn’t on Fire

You’ve been told the Sun is a giant ball of fire.

Wrong.

In this Feynman-style breakdown, we follow the simple question that changes everything: if the Sun were “burning” like a fire… how could it possibly last for billions of years? The math doesn’t work. Coal would run out in thousands of years. Even gravity can’t keep it going long enough.

So what’s really happening?

We trace the answer to Einstein’s E = mc² and the process that powers every star: nuclear fusion. Inside the Sun’s core, hydrogen nuclei fuse into helium, and a small amount of mass disappears—converted directly into energy. That’s why the Sun can shine steadily for 4.6 billion years, and why it has fuel for billions more.

You’ll see the key difference between burning (chemistry) and fusion (nuclear physics), why fusion is so hard on Earth, how we know it’s happening in the Sun right now (hello, neutrinos), and what the Sun’s long-term future looks like.

And then the part that should blow your mind: the atoms in your body were forged in stars.
You’re not just “under” the Sun—you’re connected to the same stellar process that made the universe bright.
