No- if you think about a 'classical' particle (that is, ignore quantum effects), once you are inside the particle the gravitational pull is proportional to the distance from the center.
In other words, if you are outside a spherical mass the pull of gravity gets stronger as you get closer (~1/r^2). But once you are inside the mass, the pull gets weaker. Hence there is no black hole at the center of the earth, for example.
- ibebrett 12y agoyou are correct. But what about objects moving past me at near light speeds? Would they see my mass increase to the point that I have an event horizon?
- dhimes 12y agoApparently not, but to be honest the reasons are beyond my full understanding.
- BrianKoberlein 12y agoNo, because gravitational mass is not the same as (apparent) relativistic mass. I wrote a post on it a while back, but I'm not sure of the protocol regarding comment links.
- ibebrett 12y agoI would love to read it.
