== Reliable Sources == 

 The discussion on Black Holes repeatedly refers to Reliable Sources. Such reliance held back astronomy for 2000 years ... yet you champion it when it suits your own beliefs. Like your friend, you have no objectivity about the subject and delete anything that points out the danger of relying on Reliable Sources. Welcome to a life in which you will never know anything but what others know. I give up on pointing out the obvious and having it marked as vandalism and trolling by people who cannot think for themselves.
