Could you use an existing gravitational field (for example: The Earth's) against itself? (For example, changing the direction of the field, ect...) If so, how?
Question Date: 2007-09-18
Answer 1:

Nobody KNOWS how, at least. It may be possible, but then again it might not. I suspect that it may be possible in theory using a spinning black hole (spinning massive objects can swirl space - and the gravitational field with it - as they spin). Whether it's possible in any kind of practical sense I don't know, although I suspect that the answer is "no".

Answer 2:

There is no way that we know of to change the direction of gravity. It always seems to be point in a straight line from the center of one mass to the center of another.I used to dream about being able to change my own direction of gravity as a kid... Just think of the awesome skiing you could do--for free, and uphill!
