I dont know anything about these things. No shame. Question that popped into my head:

Energy is aways converted, always lost from whatever is using it. There is no system that can put out more energy than can come in, right? So every star in the universe is burning fuel. Does that mean that eventually, be it trillions of years from now, all that energy will just run out? I know the universe is constantly expanding, but wont there eventually be not enough juice to keep it expanding? What happens then? This is probably a stupid question and I'm missing a big piece here. I know technically no energy is lost, it just goes somewhere. I dunno... Also, how does that expansion happen? Matter can't be created, so is it really just spreading out indefinitely until gravity kicks in lumping it back together?

Im not that great when it comes to physics and the laws of thermodynamics. But it is true that energy cannot be created or destroyed. Also, energy must be conserved. So all perpetual motion devices are not functional. Also, all the energy in the universe will go away, in at least one theory of the end of the universe. I believe its called Heat Death or the Big Freeze...Im not sure which

wow reading that just blew me away

Incorrect.

I'm no expert on this, but. . . if you're talking about perpetual motion, like for a motor or something, you could probably do that with magnetism. It wouldn't put out more energy than you put in, but it could convert the unlimited magnetic energy into a physical process that in effect creates a perpetual motor. If you make a circular magnetic field and put something like a top in the center of the vortex, as long as the source of the vortex is not solidly mounted, if it was put on springs for example, then the top should just keep on spinning.
But again, I'm no expert. . .

"Stars expand as they grow old. As their core runs out of hydrogen and then helium, the core contacts and the outer layers expand, cool, and become less bright. This is a red giant or a red super giant (depending on the initial mass of the star). It will eventually collapse and explode. A star's life span and eventual fate are determined by the original mass of the star."

The general idea of the mainstream cosmology mixed with Chinese mysticism will probably aid in understanding this.

In the beginning Yin (contraction) and Yang (expansion) were in perfect balance until Yang overpowered Yin creating what we call the universe in an instant, imediatly after, Yin slammed on the breaks. But since the expansion already had the momentum, no matter how hard contraction contracted it would continue to expand. Over time the breaks wear down, slowly at first, as it grows on the information before it the expansion expands faster and faster and faster and faster until all atoms are ripped apart. Or something like that, that is the general idea of the mainstream cosmological explanation.

It's nice to see that while your head is still deep in there, it is slowly coming out of your ass.

Energy and mass will reach equilibrium.... right?

Nope. Magnets lose their charge over time, especially when interacting with other magnets.

Theoretically, perpetual motion is possible, but you wont be able to draw energy from it like a generator. These theoretic involve perfectly frictionless bearings or what have you. So far, the only thing like this that we have would be superconductors. They have zero resistance, so if you were to make an energized loop, you could have the electrons flowing for eternity, providing that it is kept cold enough to superconduct.
