Black holes are relative. Inside you there is a black hole at your center of mass (its just that your event horizon is very far inside you). To things moving at relativistic speeds in relation to you, your mass is huge (to them), and you look like a black hole.
- smeyer 12y agoThere is not a black hole at your center of mass. Protons and neutrons (let alone atoms) are not dense enough to form a black hole. In all likelihood, your center of mass is empty space between a nucleus and some electrons.
- ibebrett 12y agoif you don't consider the effects of quantum mechanics then all objects have an event horizon.
- dhimes 12y agoNo- 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.
