i just thought of something, ive been trying to figure out gravity. and i have a basic understanding, but it just never satisfied me, the answers i have been given. and by the way im not sure where this thread belongs but i figured this was a good place to start. feel free to move it if there is a more appropriate spot.

alright, so my understanding is that mass determines gravity, and that it sort of bends space, like putting a ball on a tight sheet, then throwing some marbles in with it, they will orbit into the larger ball. but would that not mean that something was pulling down on the large ball? what? there is no gravity in space. it didnt make sense.

now i got to thinking about the universe, and i imagine it as a large being and we are in its circulatory system.

then i think how similar water and air are as mediums. and how if we lived in a universe where water replaced space, we wouldnt know the difference we would think it normal. and would think water never ended, and would know nothing of space or air.

so here is what i propose... we do.

gravity is not a force that pulls things to it, rather it is a force that pushes, or presurizes into other objects. space is a fluid, and the earth spinning creates a whirlpool so to speak, in space. and when you drop an apple its forced, by space, into the earths surface. and the sun rotating swirls everything twords it.

anyhow go ahead and let me know what you think.

gratefull for all of you!

well, spinning objects are not the only things that feel gravity. I have never thought of gravity as a pushing force, but I don't really see how that helps us when examining what gravity is.

as for the "we are just part of a bigger entity" thing, I refer you to Occam's Razor "one should not increase, beyond what is necessary, the number of entities required to explain anything." in other words, since there is no evidence of such a higher plane of existence, it is unnecessary. the convention of science is to use the simplest explanation for things, and only if a more complicated explanation yields better test results will it be accepted.

i just thought maybe it would give a different view of gravity. instead of looking at the earth as the source of what keeps you grounded, rather the space around the earth pressurizing you into it. maybe nobody has looked at that possibility.

That's because what you say isn't a science fact but only your opinion of what is happening.

They disproved the ether idea nearly 80 years ago

well, if you have the time would you mind explaining how they went about disproving it? or maybe some info i could read for myself?

well could you elaborate?

When you say there is no gravity in space, I believe you are confusing that with what is commonly caused weightlessness. Space is actually "full" of gravity, it's just that it's strength diminishes rapidly with distance.

If there were no gravity in space, the planets could not maintain their position around the sun, the moon would leave orbit, etc.

but what i am confused about is, where does the gravity come from? the mass of an object, right? so really what im saying is correct. we arent kept on the earth, by it pulling us twords it. rather it is bending space and everything is sliding twords it.

but since we are on earths surface space is surronding us, and pushing us into the earth.

the way i was picturing it. was like a ship sinking in the ocean. if you are near the ship as it is plumeting to the bottom, and you try to swim away, you will be pushed by the water back onto the ship.

so as we are plumeting through space, on earth, we are being pushed, by space, back into the earth.

gratefull for your help!

Well there are the the implications of your theory.

Gravity is a force, force=mass x acceleration. So this stuff that supposedly makes up space must have mass. Mass is characterized by inertia, so when you should move an object through space, you should feel inertia proportionate to the amount of space you are displacing as well as the mass of the object you are moving.

We all know that's not true.

well could you elaborate?


You have told us what you believe is your way gravity works without any scientific proof, other than what you say, as to its existance as you say it is. Can you demonstrate through mathmatical terms what you are suggesting so that we all can see your scientific methold of proving what you say is true?

Cosmic, i think he's just doing a mental excercise to explain gravity... Truthfully, no one knows exactly what causes gravity... we are still looking for a particle or field that causes things to have mass (the Higgs Field, or Higgs Boson).

i suppose maybe since i have no clue as to prove or disprove this, using mathematics, or proof, i should have posted this under philosophy huh?

so space is empty?

if there is gravity in space then, wouldnt everything be drawn to space rather then to objects inhabiting space?

rather it is bending space and everything is sliding twords it.

Gravity does not bend space, like Einsteins Theory of Relativity: that is a different subject matter.

All mass produces a gravitational force of attraction.

Your analogy of a ship sinking into the ocean is not due to the force of gravity, it is due to the fact that the weight of a sinking ship becomes more than the weight density of the surrounding water. You woud not necessarily be sucked in, but the creation of a vortex velocity (an eddy or a whirlpool around the empty space) causes a suction around the empty space that then needs to be refilled. And this is what can pull you in.

Gravity is not a very strong force compared to other forces in nature. The chemical and molecular bonds that hold your body together are forces that are much stronger than the force of gravity on earth. If you are not very far away from the earth then you would be pulled back to earth by the earth's force of gravity.

The force of gravity increases with the size of the mass of an object, and decreases with the distance you are from that object. So the farther you are away from earth, the less that force will be to pull you back in. Consider how large the moon is. It has its own force of gravity too. But because it spins around the earth in an angular momentum circular orbit, it always tends to go outwards, but its force of gravity stays in equilibrium with the earth's force of gravity, and so the earth and moon remain at an equal distance apart as they rotate.

if there is gravity in space then, wouldnt everything be drawn to space rather then to objects inhabiting space?
Gravity is only produced by mass, not space. Only objects in space that have mass would pull you toward them by the force of gravity. Space itself has no gravity without mass.

why does mass create gravity is there a mathematical equasion that can explain or is there an illustration you could give like that of einsteins? incedently i didnt think that the bending of space made much sense either. it seems very much two demensional.

thanks for your time in explaining your ideas on the matter.

Wrong.

The earth and the moon do no remain at equal distance. The moon is moving away. Albiet it very slowly. A few billion years ago, the moon was actually quite a bit larger in the sky because of it being so much closer.

The points at which the NET force of gravity are zero are called La Grange Points.

And it doesnt spin in a circular orbit... nothing does. However the eccentricity is close to zero, so it appears circular.

in an angular momentum circular orbit, it always tends to go outwards
*cringe*

Gravity does not bend space, like Einsteins Theory of Relativity
Huh? That makes absoultely no sense. Gravity is a force. Einstein's Theory of Relativity is not a Force, but a way to explain gravity among other things. Gravity does definitely bend space. Or rather, Mass bends space-time, creating the effect of gravity. This is why we have gravitational lensing.

Gravity is only produced by mass, not space. Only objects in space that have mass would pull you toward them by the force of gravity. Space itself has no gravity without mass.
If I answer your question do I get gratitude, love, or both?

It is a difficult question to answer, and as far as I know Einstein gave us the best answer. Gravity is a weak force, but all mass produces gravity. His explanation is somewhat complicated as it does involve his famous theory E=MC2. All mass is equal to energy times the speed of light in a vacuum squared. Basicalling, all mass produces a curvature in space-time and this curvature results in a physical attraction between all forms of mass.

If you contemplate on that for a while and ask me again, I'll go into more detail.
