Re: rest mass/relativistic mass question

As a thought experiment, suppose, we are accelerating a proton in a
large accelerator (as large as you need it to be). It will continuously
gain mass/energy. Will a time come when it has gained sufficient mass
energy to form a black hole? If not why not?

If yes, then what happens to an observer who is always at rest relative
to the proton? To that observer nothing is happening but then suddenly
the proton turns into a hole? Isn't physics seemingly violated for that
observer?

This is a Frequently Asked Question. Fortunately, there are informative
answers to be had in the Physics FAQ (written by one of our esteemed
moderators, no less!). Check out

particularly the "Black Holes" section.
