Re: OT: The 10th Demention
I'm just not sure what the difference would be between saying that "This object has potential gravitational energy that is being transformed to kinetic energy as it approaches another mass" and saying that "Gravity creates kinetic energy in this object as it approaches a mass, or destroys it as it moves away from a mass".
The first one corresponds with the energy conservation law, the second one does not. Can it actually be proven that the first one is more true than the second?
The reason I mentioned potential gravitational energy not being real is because it can't be put on a weight. I mean, you can weigh 'normal' energy, since it actually has mass, but gravitational potential energy doesn't, to my knowledge.
