Special Relativity and Black Holes

In summary, the theory of general relativity predicts that objects traveling close to the speed of light would decrease in length and increase in mass, effectively creating a black hole. However, this is not possible because more and more energy is needed to move an object close to light speed, and even if we could get past this step, there is no way to actually create a black hole using technology.

Whoops, I got things backwards here--the light would actually be highly blueshifted as the object approached you, contrary to what NewDescartes was saying. Only when it was moving away from you would it be highly redshifted.

Yeah I caught that, but I understood what you meant. Yes, objects moving away from you would be red shifted at close to C, to the point of non visibility. This explain's "[URL paradox[/URL].

All I am arguing is that if matter travels at velocity C, it is a black hole. Sure the original mass of the object is invariant, but the energy needed to accelerate the object to C is infinite. A black hole is needed to accelerate mass to light speed. Reference points are irrelevant due to the inability of information to pass.

Special Relativity alone accounts for black holes. General Relativity is not needed.

Well, that's exactly why it's impossible to have a massive object moving at c in SR.

How can a black hole accelerate mass to light speed? This certainly isn't true in general relativity, and in pure special relativity there is no spacetime curvature and thus no gravity to alter the motion of nearby objects.

This also seems like weird circular reasoning--you say a black hole is a massive object moving at light speed, but you also say a black hole is needed to accelerate massive objects to light speed in the first place?

If you are interested I'll share my logic with you. I don't want to come off as promoting a crackpot theory and get banned. I know how closed minded physics is and am struggling to convince Science and Nature to publish my work. The problem is I am more of a philosopher than a physicist. I do have some Mathematical proofs to show, and a descent idea for some experiments and possible predictions for results.

I'm closing this thread, which, as indicated by its title, has never been about mainstream relativity.
