Aga: I was saying it was American of you to point out the difference in spelling, not the way you did it.
In my example with the drill, the gravitational pull increases indefinately as you approach the COM of Earth.
In this scenario, you don't just simply "plug in" the numbers into the formula. You have to take the limit as the radius approaches by zero. As a result, I am right.
And Aga: to disprove your example to disprove me:
If something were in the center of your hollow sphere (it would have to get there somehow, it wouldn't come to rest there naturally unless some serious lucky throwing happened), it would sit there. The attraction from all sides would be equal. If this is -not- what you meant, let me know.
Also, Aga: Your technique for travelling faster than light is not new. Yours is a basic example of what people thought would be the first way to do it. In practice it is impossible, because we have no way to move black holes, and we aren't even imaginably close to creating an electromagnetic force generator strong enough to rip through space-time once, let alone three times.
I should further add that according to relativity, infinite energy is possible. As a mass approaches the speed of light, it's relative mass increases, approaching infinity. e=mc^2...
Dig through the archives of my site (http://www.avinashv.net/archives and there are some astrophysics articles I wrote. http://www.avinashv.net/2005/04/13/black-holes/ is probably my best, though, at a year old, it's badly written and flawed.
