1) I recently read an answer to a question I asked some time ago. The question had to do with a person falling into a black hole. From the persons reference frame he hits the bottom very quickly. From the reference frame of a person outside the gravity well, he doesn't hit the surface because the black hole evaporates in a finite time while time dilation causes him to go slower and slower. The answer was that he hits the surface just as the black hole completely evaporates. But then the scientists finished by saying that it was an elusion because he hits the surface very quickly. I didn’t think there was any elusion here, what happens is real, the difference only depends on your reference frame. 2) Following this thought: I just read about the Einstien-Bose condensate theory of black holes. Isn’t this another model for what I’m saying. If from the reference frame outside the gravity well a person takes an infinite time to hit the surface (singularity) than the black hole can never really form a singularity as it takes an infinite time for the star to collapse to a singularity. Once it collapses beyond a neutron star it becomes some exotic substance that’s not made of sub atomic particles.
Re: Is relativistic length contraction/time dilation an elusion?
