::::::::: Additional note: As RSchlafly points out, there are many claims about black holes which ARE unfalsifiable, currently - as he points out, claims about the interior of the event horizon are not falsifiable. Similarly, predictions regarding their presence in certain locations are not falsifiable by any means we yet possess. The same criticism could be leveled at my above description of an experiment in nuclear-density matter. [[User:JacobB|JacobB]] 12:56, 9 August 2009 (EDT)

:::::::::: We cannot determine what is happening in the "interior" (inside the event horizon) but that doesn't make a black hole itself not falsifiable. We are not sure what the interior of a neutron star is at all, but I think everyone here agrees they do exist. Also just because you cannot visually see something (such as a black hole, where light cannot escape from inside the event horizon) doesn't mean it isn't there or falsifiable. Most astronomical study of space is not in the visual spectrum, and there are many ways to determine the existence of a black hole. I also must point out, there has been no alternative hypotheses to explain the gravitational effects we presently attribute to black holes. Also, as pointed out before, if we are able to find an object of sufficient mass within the Schwarzschild radius, which normally would continue to collapse into a gravitational singularity (Black Hole) ''but has not'', that would disprove the theory of Black holes right there, or in other words falsify them. For example, if we found an object the same mass of our Sun, and was smaller then its Schwarzschild radius of around 3 km (the Schwarzschild radius for an object of that mass) and it '''did not''' collapse into a black hole, then the theory of Black Holes ''would be proven false''. --[[User:BMcP|BMcP]] 08:14, 12 August 2009 (EDT)
