Stephen J. Crothers first is a mathematician not a physicist. His argue is Einstein theory is mathematically unsound. This is why he attacks physicists for there theories his belief is space time is linear and not curved In a linear model space time cannot be warped and there fore black holes cannot exist. He also claims that the mathematics leading to curved space time does not exist this is the basis for his theory.His problem with the math?Eventually it Gets to the point in math you cant divide by 0 and this must happen in a singularity.If space time is not curved this cannot happen at all.
Now i know at least one point hes wrong he claims the math doesnt exist to even deal with curved space time.Tools like the Lie derivative, metric connection and pullback functions are all used to do calculus on curved space-time. Even if you don't think space-time itself is curved, the maths of dealing with the notion of curved space-time (or more obvious curved surfaces like that of a sphere) is very well developed, so you can't deny that the tools aren't there. As for the rest not done with my degree and right now im not willing to argue which model is correct but currently observations support relativity. So untill we have a better idea black holes still need to exist.
There is no other end. A black 'hole' isn't a hole, its a point of incredibly intense and powerful gravity. People like to speculate that it could be so instence that it fold space up in some whacky way that actually leads to another dimension or whatever, but thats all very speculative.
