On black holes and relativity.

[James Leighe]

Ok, starting with a 'test' universe with only two objects, a single particle and a neutron star just under the mass required to collapse further into a black hole.

If the particle was set in motion near the speed of light, in it's reference frame the neutron star would gain (significant) relativistic mass correct?

So, in the particles reference frame, the star would collapse into a black hole... But in the stars reference frame it would still not be massive enough to collapse right?

I obviously missed something important here, if someone can just correct me that would be nice.

If you go too fast, do you become a black hole?

Thanks, that was exactly what I was looking for.
