Gravitic acceleration..does not exist

hehehehe

if it does exist.. where does the energy come from to
accelerate mass.?

oz? your hip pocket? hopes and dreams?

occam

 

-9.8m/s2'd?

 

Lan
thats the math
a description of the thing.
where does the energy come from? to get 9.8mpsps

It seems to come from nowhere.. a mass in intergalactic space[virtually flat]
will accelerate to another mass, no mater if it is lightyears away.
Why?
what makes 1 trillion tons of mass acceleate to a place .. energy
where does it come from.? why, is it never exhaused.
I was once told that true philosophy, and science, is asking the right questions.
To me, these are the right questions.
And yes, the most difficult.

i saw that his post went away.
so far 4 threads have uses after me that i cant see.. explain please.

ah yes we cant have anyone too smart on the forum

where do you think the energy comes from? i havnt heard what you think yet, just your question. i know i got stuck in this loop before, and i still dont remember how gravity powers itself. i think it gets its power from the devils soul incinerator. thats the only thing that makes sense to me.

 

Sorry, wasn't around;
What you're saying is basically that, since energy cannot be created or destroyed, and all action (actions requiring energy to occur) has to be the result of a transfer of energy, objects should not gravitate to each other, because the energy to do so has no source, seemingly it comes from nowhere.

The answer you're looking for may be in interactive forces
http://en.wikipedia.org/wiki/Fundamental_interaction
you could note that the proposed mediator for gravitational interaction has not actually been discovered yet. Unfortunately, there can be no certainty that we will find out how gravitational attraction works within our own lifetime, but if you continue to pose the question, maybe others will look harder for the answer.

this is pretty awesome too

Unless gravity is not an energy like other energies but a constant quality of the universe which is constantly userped by energy. Perhaps the true expenditure of energy is in opposing gravity.

Gravity can never be harnessed as an energy source - we can merely use gravity to direct the flow of energies.

Eg - how can we use gravity to power a generator? IF gravity was really an outpouring of energy, then we would surely be able to drain it out. But this is impossible. In order to actually utilise gravitational energy, we must use more than that amount of energy to set up a situation whereby an object is far from earth.

you could say that the energy that pulls you to earth 'comes from' the energy you used in jumping away from it.

 

This is a great question.
You are correct in saying that it has not really been neatly explained. But it has been observed.

I see it this way:
Theoretically, all the energy, mass, and even space itself, originated from the big bang.

It has been proven that the universe is expanding. (The doppler effect)
So gravity is the universe attempting to contract again; the opposite effect of the expanding universe.

Project the force of gravity into the future. Eventually the force of gravity should, I imagine, contract everything in the universe into a gigantic super-black hole. The gravity here would be so large, that, not only would light not be able to escape, but even space itself would be sucked in: The big bang in reverse, or 'the big suck'.

In the early stages of the Universe, the distinction between energy, space and mass was not as obvious as it is now. In a similar way, if you increase the speed of an object, near to that of light, the excess energy you add does not add momentum, instead it actually turns into mass. So the faster you go, the heavier you get. But this digression just shows how the universe is not quite as neat as it looks from the Newtonian (f=ma) perspective.

Another example is this : The whiplash effect is used to accelerate small objects like man-made probes at far greater speed than normal, by moving them into extreme orbits next to large gravity bodies like Jupiter and the sun. The probe effectively sucks the energy out of the bigger body, slowing it down a bit. The amount of energy required to slow down the bigger body is proportionally really big for the small probe. So it flies off at a massive speed.

Essentially then, gravity is like a complex web of invisible elastic bands that unite every atom in the universe to each other. The potential energy of all these gravity fields was already in place when the universe was created.

I hope this goes some way to laying a foundation for your answer.

 

Hydroelectric energy uses gravity as a power source.
As did the Aqueducts of ancient Rome.

 

but robs the gravity of the streams the dams keep back, altering the weather ever so slightly, but on a large scale over a period that makes the environment react to it as if it were natural.
you alter the path of energy, but it still comes at a cost as the energy goes where it wasn't going to

*Im stoned atm however, so please excuse me directing that at the guy with the most solid post in this thread
