Gravity pulls object to its center correct?

Gravity is not infinite but it has an effect on objects up untill they are an infinite distance away or they cease to exist correct?


My serious question is where does this energy come from! If the above is true then the gravity from a star 9billion light years is there. Obviously it has no serious or noticable effects because of extreme distances like this in space...but where does gravity get the energy to pull all objects towards it?!?!


Additionaly one of Jupiters moons, Io, has volcanic activiy because of jupiters massive gravity having a force on the moon heating it up through friction. The energy that powers those volcanoes then is gravitational in original??!?!


My ultimate idea is the ability of humans to harvest energy from gravity into a usable source of energy.

Iso answers/input/ideas!

we don't know for sure how gravity works. we have some very good guesses but thats it.

we use gravity for energy all the time. basic example is a dam. gravity forces water down from a higher point through turbines to generate electricity.

harnessing gravitational energy in a raw form would serve no real purpose since its gravities effect on objects that make it so powerful.

Interesting. I thought we knew more going to keep bumping this thread n see what else I get. Also! the water from a dam is not what im looking for at all. The water absorbed energy from the sun to evaporate and rise eventually raining down over land and creating rivers that fund the dams energy therefore this energy is really just from the sun in an indirect way im looking for raw energy from gravity & answers to my questions!

...there is a lot of mounting evidence that gravity pushes instead of pulls .

I cannot understand how gravity pushes.
I, too, believe that gravity, other than dams, could be used for power.

gravity isnt energy , its a force ( one of only 4 forces that we are aware of )

If you don't like the hydroelectric dam example, how about tidal generators? That's pure gravity doing the work.
You can't really harness a static force for energy, though. It has to be doing some work, moving things somehow. Otherwise we'd be building generators out of stretched rubber bands or magnets. (by the way, how do they work?!?!)

this force can pull an object to it the size of texas and bigger. Much bigger. This force does not then use energy to do this?



this just sounds retarded...Go pick up a rock and lift it in the air..Let it go and see what happens!





tidal generators is an AMAZING exmaple I never even thought about that! Since the gravity from the moon and sun greatly contribute to the tides this energy of harnessing waves comes directly from gravity and to harness it would be to harness gr avity?

Okay, I'm not too old (15) so don't laugh at my logic...

So... More mass = more gravity correct?

If I understand correctly... Something inside that mass must produce, or have something, that gives it a gravitational pull... (I.E. Electrical field, magnetic field, protons, neutrons, I don't know... I'm not an expert at this..)

So something about an atom (or something) must have a direct connection to gravity..

Just some thoughts to think about

Mass emits gravitons, according to theory.
