News from CERN anti matter lab

If you can wait 2 more years, they'll probably be creating a few black holes.

I'm curious how they know what the zone of influence of a quantum singularity is? Does the standard gravitational reverse square of distance apply with a singularity?

Wouldn't that be inverse square?

inverse, reverse, whatever.. they sound similar! 😉 I don't routinely deal with newtons equations anymore and I can't even remember the formula without looking in a book. Hell now that I think about it more closely I don't even know what a reverse square would be? A square root?

So yea, how do you determine the zone of influence of a singularity, including a quantum singularity? I mean by definition it's a singularity so shouldn't it's zone of influence be infinate? (I know in the real universe that's not true) Isn't a black hole what happens when you divide by zero?

For every doubling of the distance, the gravity is half.

In theory the gravity is infinate is it not? What's half of infinity? I guess that's why I don't really understand singularities.

For every doubling of the distance, the "force applied due to gravity" is halved, but I think the force is inversely proportional to the square of the distance.

Only if there are extra dimensions though... and quite a few of them at that 😛

Yep it does. Compress the earth into a 1cm diameter ball and it'd be a black hole. The dynamics at this radius would not change though. The gravity produced would still be the same for all points outside the current surface of the earth. There is no real infinity with this.
 
gravitational acceleration g = Gm/r².

centripetal acceleration in orbit = v²/r, or for light, c²/r.

At the event horizon, this orbital acceleration = gravitational acceleration, so
c²/r = Gm/r²
c²r = Gm
event horizon radius r = Gm/c²
