My theory is that if we can harness the power of gravity, (gravitational fields), we could create a propulsion system that could speed to 186,000 miles per second or more.

Um... no. First of all, gravity is a force of attraction between two masses, so rather than propulsion, you'd pull yourself toward your destination, and it's directly proportional to the masses of the two objects involved, so to overcome the pull of the earth or our sun, your destination would have to be enormous (like several galaxies-worth of mass. Additionally, as distance increases between the two objects, the force goes down exponentially, so you're not going to get much force if you're light years away (since I'm assuming you're talking about travelling through deep space and not to, say, Cleveland).
If you're talking about anti-gravity, the answer is a definite no -- anti-gravity itself is only a theoretical concept proposed by SOME physicists, with no physical evidence of its existence, other than the dark energy theory that some cosmologists have come up with in the past decade. Besides, the repulsion you would get from a force exactly opposite to gravity would be just as miniscule at large distances, so you'd have the same problem.
Oh, and that whole 186,000 miles per second thing? Can't be done, according to Einstein. I'd read up on relativity theory.

Because gravity is the standard by which energy is measured. There is no "gravitational energy". In other words: The "force of gravity" only works in the downwards direction. items only fall DOWN, not up. So, it MIGHT be possible to cause an object to generate energy by causing it to fall down -- like causing a magnet to fall down a tube lined with a wire coil. magnet moving in coil of wire = electricity. BUT For the magnet to fall, it must first be taken UP. How do you do that? Well, a winch or an elevator, maybe. And how do you run that? Using electricity! So, all the electricity you could make by causing the magnet to fall through the tube would be wasted in powering the motor to get the magnet back up to the top of the tube! people have been trying to harness the power of gravity for years. they are called Perpetual Motion Machines. they don't work. In fact, they don't work so much that the United States Patent Office will refuse to even look at patent requests for a perpetual motion machine. BTW: Gravity is the WEAKEST force in the universe! it holds planets in orbit because there is so much of it!

Trebuchet! It harnesses gravity and propels.
There was a guy claiming to have worked at Area 51 and had seen such a device and went into detail how it supposedly worked.
Scientists can levitate a small frog using an extremely strong magnetic field. But what this means is...? It is either shielding gravitational force, overwhelmingly stronger than the gravitational force, or is gravitational force.

Any kind of system that harnessed the power of gravity would have to be in a gravitational field so you 'd have to take it with you. A hydroelectric generator harneshes the energy of gravity but you'd have to haul the earth around with you.
It doesn't sound practical.

What do you mean, power of gravity?
Gravity is a force. It does not have power. You can do work against the force by moving objects apart, and this is released if they move back together again. But you never get out more than you put in.
As a source of propulsion its a total non starter.

Well, the late show dropped a safe on a old Buick on YouTube. That harnesses the potential energy of gravity. Put a pretty good dent in the roof.

Sorry, but this will never happen. What you describe is some sort of a perpetual motion machine. The Laws of Physics show that it simply is not possible to create such a device.
I do wonder how you got this velocity though....see Terminal Velocity.

Not possible without a complete re-write of General Relativity. This is not impossible (unlike Special Relativity, General Relativity is not yet a done deal), but it is extremely unlikely.

Did you read this in one of those weird "World News" papers at the grocery store about two-headed vampire babies invading Iraq?
