OT: The 10th Demention

[Suicide Junkie]

ALL the fundamental forces do not fade with time. Gravity is nothing special.

The only reason why everyday forces fade is because they do work on stuff and thus dissipate the energy into the environment.
If you don't let your Bowling ball fall, it dosen't lose any potential energy. If you don't let your spring expand (or rust out!) then it dosen't lose any energy. If you don't let your flywheel interact with the environment, it won't slow down, but it will still be exerting a lot of force to keep the outer edge of it moving in a circle.

Conversely, if you use a realistic flywheel, the bearings will introduce friction and sap your kinetic energy into heat and noise.
If you use a realistic spring, it suffers chemical reactions, and metal fatigue.
If you have your bowling ball sitting outside, it will sink into the mud.
