Okay, so you say 30 kilometers. And this one here is 3 kilometers. 3 kilometers, that's how far down, how scrunch it would be. And Earth, you can only imagine Earth if you get scrunch of Earth down. You're looking at inches, centimeters at that point through the Earth. And that can be calculated just as a specific formula or equation for that. The Schwartz-Child radius formula, which is R subscript S equals 2MG over light squared. 2MG, that's the mass of the object and the gravitational constant. You multiply that divided by the square of the speed of light, that gives you the radius. So yeah, the Sun, that's 3 kilometers. Incredible. But as I said, the Sun doesn't have enough mass. When our Sun finally winks out, once it extends all its fuel, it won't end up as a little dwarf. Mind you, those white dwarfs are very, very dense. The next one here.
