how is gravity creating warmth, please?

Another thing is density determines the range of gravity. The longer the range, the less change in slope-decline per-square-astronomical-inch. This is why, on the surface of the moon (a relatively small object), you can fairly easily float off into space. A simple jump off a trampoline might do the trick, because there is so much change in the slope decline.

Of course, this means the gravity objects we create only need enough density to produce the necessary range. In other words, these objects do not need to be nearly as dense as the Earth (whose gravity range stretches beyond the moon).

The constant pulling and tugging at the moon causes the shape to warp and the subsequent friction generates geothermal heat.

What if you created a circle, with an object in the middle to 'spin' around the circle. The middle thing is being 'spun' by using these gravity devices. It would be like infinitely rolling down a slope in neutral. How fast could it go? Would it ever stop accelerating? If not, what would happen when it broke the speed of light?

If you could create this particular device, you could use it to generate electricity in cars (wouldn't need any new infrastructure), and it could be a direct energy device for something like a propeller. Although, if we created an inter-continental train system using the 'alternating-slope' idea, it's possible these trains would allow us to travel from continent to continent in minutes (depending on the rate of acceleration, and if some kind of speed equilibrium is somehow reached).

Is it possible to increase the density of an object by using nano-technology? I don't know much about nano-technology, so i'm just kind of throwing this idea out there. With this tech, if you can move little tiny parts around, so you can concentrate them into a smaller area, it should function to increase density while decreasing size.

Perpetual motion machines have never worked and never will because they defy the basic laws of physics. Kinetic energy has to come from somewhere and even then an object of mass cannot exceed the speed of light in fourth dimentional space. Unless there's a hyperdimentional loophole you're stuck.

Density is dependent on how closely atomic nuclei are to each other and on what elements they are. The interaction of electron orbits prevent them from passing too close and there's only so far you can reduce the radii of those orbits. Short of that you'd have to strip the electrons completely, but that's plasmerization and that permits nuclear fusion. So no, barring any truly earth shattering discovery of subatomic manipulation nanotech won't cut it.

I don't read textbooks... at all. I didn't even read them when I was in school. Pretty much everything I come up with, I do on my own, just by thinking. Occasionally, I randomly stumble upon something and fall in love with it (like Einsteinian gravity).

It does make sense an equilibrium would be reached based, aside from atmospheric conditions, on the weight of the object and the level of gravity. If these gravity devices work, it means, even though we wouldn't be able to reach infinite speeds, we should be able to break the speed of light and much more. The same method of creating ultra-small yet ultra-dense objects could be used to create heavy enough objects (the gravity objects would simply have to be dense enough - steepest slope-decline prevails).

if there is life on that tortured moon it must wish it were dead.

Deep below the surface, there might be vast oceans warm enough to support all kinds of life.

is this happening out on Pluto too?
