:::::: How might one falsify the basic assertion about black holes: that black holes exist such that light cannot escape? Every time one observes light escaping, he simply concludes that it is not a black hole.--[[User:Aschlafly|Andy Schlafly]] 11:31, 9 August 2009 (EDT)

:::::::Mr. Schlafly, you're absolutely right that the general claim, "There are mysterious regions of space from which light cannot escape" is an unverifiable claim. Black holes don't refer to this statement - they refer to the specific statement, "It is possible to concentrate a certain amount of mass, so that the gravity of that mass prevents light from escaping." This could be falsified by experiments in particle accelerators (possibly the LHC, I'm not familiar enough with it to know) which could demonstrate that such concentration of matter is impossible - that degeneracy pressures, currently unknown, prevent such it. This would falsify the claim that black holes exist. [[User:JacobB|JacobB]] 11:52, 9 August 2009 (EDT)
