**Abstract:**

Cosmologists always claim that their black holes, mathematical fabrications entire, have an escape velocity. They even have an equation for it and by using this equation they assert that the ‘escape velocity’ at their black hole ‘event horizon’ is the speed of light. This event horizon, they say, is at the ‘Schwarzschild radius’ of their black hole; and they have an equation for that too. On the other hand, the cosmologists also always assert that nothing can even leave the event horizon of their black holes. Light, they say, hovers forever at their event horizon as it tries to leave or escape the clutches of a black hole. Thus, according to the cosmologists, their black holes have and do not have an escape velocity simultaneously at the same place. However, nothing can in fact have and not have an escape velocity simultaneously at the same place. This schizophrenic character of the black hole is sufficient to completely invalidate it. But there is more. Escape velocity is a two body relation – one body escapes from another body. The black hole is, by its supposed mathematical construction, a one mass universe. Consequently the very concept of escape velocity does not even apply. Obviously, no cosmologist understands the meaning of escape velocity.
