Black Holes
... The radius at which the escape speed from the black hole equals the speed of light is called the Schwarzschild radius. Earth’s Schwarzschild radius is about a centimeter; the Sun’s is about 3 km. Once the black hole has collapsed, the Schwarzschild radius takes on another meaning – it is the event h ...

This mass cut-off was thought to make all such supernovae explode with about the same intrinsic brightness, allowing ...
