Surely this is all the wrong way round. The null hypothesis would naturally be that 'no black holes exist'. This is of course falsifiable if black holes are detected. From our understanding of the laws of physics and observations made, the only reasonable conclusion as it stands is that black holes do exist. [[User:RobertWDP|RobertWDP]] 19:22, 3 April 2009 (EDT)

: Exactly. In this sense, "black holes exist" needn't be falsifiable (in the absence of evidence, there's no reason to think it is true instead of the null hypothesis) in order to be scientific.
