I don't get this non-falsifiable argument. If we see light from a star, then it is not a black hole. Any claim that it is a black hole is then falsified. Black hole theory says that a star becomes a black hole whenever its mass goes inside its Schwarzschild radius, it becomes a black hole. So if we ever find a star that emits light and has its mass inside its Schwarzschild radius, then the theory is falsified. [[User:RSchlafly|RSchlafly]] 10:32, 28 July 2009 (EDT)

:The problem with that argument is that we live light years away, so what we could be seeing at one moment could be just the beginning before the light is swallowed into the black hole. --[[User:ChrisZ|ChrisZ]] 11:01, 28 July 2009 (EDT)
