The SUN Should Have Died Billions of Years Ago — Feynman's Proof

Описание: The Sun burns 400 million tons of hydrogen every second. By every 19th-century calculation, it should've run out of fuel before the dinosaurs even existed. Lord Kelvin himself declared the Sun couldn't be more than 30 million years old — and his math was flawless. So what was he missing?
In this video, we trace a puzzle that consumed physicists for over a century: why does the Sun still shine? Drawing from Richard Feynman's treatments of nuclear physics, quantum tunneling, and stellar energy in The Feynman Lectures on Physics and The Character of Physical Law, this lecture reconstructs the mystery step by step — from the failure of chemical energy, through Lord Kelvin's gravitational bet, to the shocking quantum accident that makes sunshine possible.
