From a couple of posts, including one of yours, there is no conventional view. No one knows why gravity exists.

No one knows why gravity exists. Are you asking why gravity exists or do you actually wish to know how gravity works?

I'm not sure what you are asking?

Well it is one thing to explain the mechanism{how} for which the phenomena of gravity occurs ,however the question why seems to be inquiring of the reason for gravity being a phenomena in the first place.

I am asking How does gravity exist.

You forgot the other 2 criteria. By your standard, I could offer any crackpot idea about these things and be taken seriously.

The mechanism for gravity is given in Einstein's General Relativity and if you want to know how that would be the place to start.

mpcDCCLV writes: My crack-pot theory is that all objects displace space, and it is this displaced space that causes objects to remain in orbit around one another. If gravity were due to (massive) objects displacing space, then those objects would be pushing each other away - gravity would be repulsive. The 'amount' of space between objects, which is just the way we measure how far apart they are, would increase if more objects were thrown into the pool, displacing some of that space. So, you need to petition the government for funds to do some experiments to test this predicted result of your theory: that gravity is repulsive. You would stand a pretty good chance of winning an Ignoble prize.

Shortly after Newton's work was published, a 'how' theory of gravity was proposed. This theory stated that space is full of invisible particles zinging around at high speed. These particles are constantly bombarding large bodies, like the earth, moon, etc. and bouncing off of them, thus exerting a constant pressure on them. If a body is in isolation, the pressure is the same from all directions and there is no net effect or motion. But if two bodies are near each other, they 'shadow' each other from the bombarding particles on the side of each body facing the other body, while the number of particles bombarding the opposite side is not diminished so that there is a net imbalance of force pushing the two bodies towards each other. This force has exactly the 1/RxR (one over R squared) dependency as Newton"s law! Of course, this explanation just replaced the "why is there gravity" question with a "why are there these particles" question, but since the answer to the latter question is self evident, this would still be a major advance in our understanding. This explanation was discarded for a variety of reasons, but google on "Casimir force" for a more recent application where it works quite well.

Gravity is both attractive and repulsive, depending upon how far two objects are from each other. The sun displaces more space outside the earth than it does between the earth and sun, so that is why the earth stays in orbit around the sun. If the earth were further away from the sun, then their spacial displacements would cause the earth to be pushed away from the sun. That is why we see an accelerating, expanding universe.

Now all you have to do is put paper and pencil where your mouth is: show that your theory predicts the observed elliptic orbits of the planets and their moons. Be sure to show all your work so that your analysis can be followed, understood, and verified by anyone with the proper background. The currently accepted Newton/Einstein theories predict these orbits to within parts per trillion, so you'll need a calculator with lots of digits.
Or am I just too dense to know when my leg is being pulled?

No legs are being pulled. Maybe that's just spacial displacement you are feeling.

Mpc, please don't take this the wrong way. The reason many of us are questioning you is because we've encountered too many crackpot theories before. The biggest misconception among student age groups about science is that any idea that even remotely make sense to an individual's common sense can be called "scientific". It's not that we don't appreciate your effort in trying to understand reality and science. It's that to be taken seriously in the serious world of science, you need much more than a simple common sense based "theory" to explain natural phenomena. You need at least some supporting data for your "theory", a detailed report on experimentations you've performed so that others can repeat them, and repeatability of your predictions. So far, you've given us nothing but an idea (an interesting one at that, but just an idea nonetheless) with absolutely no supporting data or logic whatsoever.
This is one of the reasons why creationism is so attractive to the ignorant masses (pardon the term). All you need is read the first few pages of the bible and then you can proclaim yourself a "creation scientist". You've mentioned before that you are not religious. Well, I certainly hope that you don't follow the same path that creationists have taken.
