would it be possible to make energy (albeit a small amount) out of this, i think this kids on to something
User avatar #49 to #9 - daentraya (02/26/2013) [-]
I'm fairly certain that harvesting any energy out of it would stop the motion. For there to be energy, some of the motion has to be lost, and it seems that its only just about able to move like that
User avatar #57 to #49 - tigersstripes (02/26/2013) [-]
That is a good point.

scientific laws and theories generally deem perpetual motion impossible
User avatar #60 to #22 - aetherpig (02/26/2013) [-]
True, but it's been done. What can science say to that?
User avatar #23 to #22 - tigersstripes (02/26/2013) [-]
while technically yes, reality proves those laws wrong. Perpetual motion has been managed and thus laws and theories must change, and that is one of the things that separates christianity and science.

Perpetual motion has never been achieved... at least not on earth.

Forgive my bad gif, but that machine can spin infinitely so long as there is the correct force of gravity, pressure, etc as on earth.
User avatar #39 to #25 - Lambda (02/26/2013) [-]
A body rotating in the zero-gravity vacuum of space is the only example of perpetual motion I can think of. It will never stop spinning without a force acting on it.
User avatar #63 to #39 - aetherpig (02/26/2013) [-]
Actually, you would EVENTUALLY stop, because there's no such thing as "empty space"

You're constantly being pulled by some mass larger than you, even as far away as you can possible get from anything. It may take several billion years, but you'd eventually be pulled to a stop by the gravity of the stars around you

You just made me realize something: the earth, the moon, and the sun are all examples of perpetual motion. Not a speck of light is showing, so the danger must be growing! Are the fires of Hell a-glowing? Is the grisly reaper mowing? Yes! The danger must be growing, for the rowers keep on rowing!
And they're certainly not showing any signs that they are sllloooowwwingggg!!!!!!!!!!!!!!!!!!!!!!!!
User avatar #27 to #26 - jacklane (02/26/2013) [-]
no.... let's look at the definition of perpetual motion: The motion of a hypothetical machine that, once activated, would run forever unless subject to an external force or to wear.

The sun is finite.

There have been a few machines built in the last 200 years that seemed to have perpetual motion , but they are all fake really...

check out en.wikipedia.org/wiki/Perpetual_motion

I suppose the sun will burn out someday. But now that begs another question: will the Earth ever...die? I mean, the sun, it will burn out, but that's like a battery dying, while the Earth is like a rock with a fire inside and another rock inside that one. Will it just last forever, even after the sun?
This could also be analogous with deism, the belief that god created earth then left/died. What if that's what it's like, the sun creating everything, then burning out, leaving the Earth to fend for itself?
Don't get me wrong, I'm just rambling here, I know the sun didn't create everything, and that by the time it burns out we'll be long extinct, but still, it makes me wonder. Isn't that the point?
#64 to #30 - aetherpig (02/26/2013) [-]
Eventually over a large period of time the earth would have a sort of atomic decay (Mind you this would take an extremely long time) thus eventually reverting most minerals to basic forms. Without the sun, the gravitational plane would also be somewhat imbalanced which would freeze us over, so we would never get to see much of the effects.

The sun will one day engulf the earth.
User avatar #34 to #32 - antisocialtwilight (02/26/2013) [-]
Oh, right, I forgot about that bit.
Well, it doesn't have earth specifically, for my example. I'm just talking about planets in general. What I'm getting at is this: is the universe is like a radio run on batteries? Once the batteries die, for example, will the radio will still be there, there just won't be any more music? Also, what would be the metaphor if that wasn't the case, that once the battery dies, the whole thing is finished?

Does that mean I win? Were we competing? You need more quarters, and I need to think of that metaphor or analogy.

well i think that it takes a bit more knowledge now, perhaps we start on the small scale of the planet and slowly step by step expand to the universe. What would happen, say, if the core of earth managed to burn its self out? would it be more like a lightbulb, and once it's burned out you can't just replace the inside, you have to get a whole new one?
jumping in to random conversations
User avatar #65 to #58 - aetherpig (02/26/2013) [-]
If the core were to "burn itself out" it wouldn't change a whole lot. Earthquakes would stop..So that's something (Due to the entire core along with the mantle to be cooled (So that it wouldn't reheat itself)). I guess we might, maybe, a little bit die of radiation poisoning? If I'm correct, the cooling of the core would leave the molecules semi-dormant and release all heat to the surface. I suppose it depends on the method of cooling that's taking place.

Not really, because there are no examples of perpetual motion. It has never been found anywhere. Excerpt about planets and such below:

"Strictly speaking, planetary orbits are not perpetual motion. As the planet (and their star) rotate around their common center of gravity, they emit gravitational waves. Those gravitational waves drains the planet/star orbital system on energy so the planet eventually get's closer and closer to its star.

Now this orbital decay due to gravitational wave emission is ridicoulusly small so it has only been measured for extreme systems like binary neutron stars (which are heavy and may orbit each other within minutes, seconds or just a fraction of a second). Our planet Earth is subject to gravitational wave emission as well, but the orbital decay is so small that it in practice won't affect earth within the Suns lifetime, instead of Earth spiraling into and being devoured by our Sun, it will rather be our Sun (turning into a red giant) which extends beyond the current orbit of Earth and thus devours it.

So even by cosmological timescales, planetary motion around a star will go on for a long time, e.g for the lifetime of a sun-like star and beyond."

I'm pretty sure the sun expands passed the earth at some point. When it becomes a red star. Haven't looked into it or anything, just remember hearing that.
User avatar #35 to #31 - antisocialtwilight (02/26/2013) [-]
Oh, right, you're completely right, I forgot that part.
#10 to #9 - aetherpig (02/26/2013) [-]
According to math, yes
According to science, no
There, simple answer
I got yelled at last time for explaining it
User avatar #11 to #10 - tigersstripes (02/26/2013) [-]
uh. Ok thanks...?


i did kind of ask so i couldn't morally yell at you
User avatar #12 to #11 - aetherpig (02/26/2013) [-]
Basically, math says it's possible due to weight and the force it takes to move the object you're moving
Science says no, because it doesn't like the idea of an infinite energy source since infinite energy is illogical (Or something like that)
It reminds me a bit of religious people
User avatar #13 to #12 - tigersstripes (02/26/2013) [-]
so science says no because no? i feel lied to.
User avatar #14 to #13 - aetherpig (02/26/2013) [-]
Yeah basically. I don't think anybody has ever been successful in making an infinite energy source (At least not practically and at a good rate). Besides, even if you were to make a functioning perpetual-motion-energy-converter-thing, it's always easier just to get some slave labor and make them push carts or something. It'd be much faster than trying to make a functioning ratio of weight:gravity:intertia:energy whilst being largely beneficial.

If I had to guess, it would give enough power to charge your phone

In several years

If the battery hadn't ran by then

....But I suppose it's possible Maybe
User avatar #17 to #16 - tigersstripes (02/26/2013) [-]
well i'm not learned in the fine tunings of energy synthesizeation (or even the word for making energy useful to humans) so there isn't much of an argument i can make.
User avatar #18 to #17 - aetherpig (02/26/2013) [-]
Yeah, I'm just going off of some basic physics and shit

But you know what's cool?
String Theory
User avatar #19 to #18 - tigersstripes (02/26/2013) [-]
oh lord.
#20 to #19 - aetherpig (02/26/2013) [-]
It's the theory that rather than space/time/gravity/fabric of the universe/etc being made up of infinite 0-Dimensional points, our world is made up of a large omni-dimensional string. This string, being divided so many times by the shift "downwards" in dimension thus becomes invisible and in some cases making up of the fundamental laws of our universe.

Cool, huh?
#21 to #20 - tigersstripes (02/26/2013) [-]
you just explained it in 2 sentences while i still didn't understand off several pages of wikiapedia. you win. have some cake.
