I have been thinking a lot about the question: If a mass moves close to the speed of light, does it turn into a black hole?
But I didn't find the answers satisfactory. I have two options:
Ask the question "WHAT happens if a mass moves close to the speed of light", cite this question, and then see if it gets a response, if not then create a bounty.
Is there some way to place a bounty on THIS question, with the added rule that I want a more rigorous mathematical derivation/description of what the observer sees and what the relativistic object sees.
If there was a way to accomplish (2) I think that would be better for the community because:
a. There are fewer questions asking almost but not quite the same thing.
b. Almost anyone that reads my hypothetical question would be interested in the OP's and vice versa.
