Okay, correct me if I am wrong but Schwarzschild radius of an object if it squeezed to a radius of that point it will collapse into a gravitational singularity and become a black hole. For example, if the sun has a Schwarzschild radius of about 3 kilometers. If we were to be squeezed the sun to that diameter, it would theoretically collapse into a black hole right? If that is true, I don't understand. Even if you squeeze the sun into a gravitational singularity, it would still have the same gravity, which is not efficient enough to trap light. So how can this be true?
