You have the point. The Sun is moving, it controls the game, where it goes the planets follow. Irrespective of how you percieve gravity we are on safe ground to this point. I have concluded that the only way the planets can move is by following the Sun, as it moves we have the opportunity to observe where the planets orbit, If gravity travells at a speed (in my explanation of gravity C is favoured but as it is particl based I may have to settle for a slightly slower speed
) there must be a lag for they are orbiting a Sun that was there minutes or hours ago. If the cone shape is present it would be easy to work out the speed of gravity. If it is not there (all planets orbit the Sun in a direct line in the pos it is) then it may be that gravity is instant. However this may also point to a property of gravity as acting like an instant glue on all the solar system (which is sortta like my gravity idea but I think C is probably the speed tha glue works at)..not very scientific but I am trying to convey quicky short ideas on a big subject.
Gravity is something that fasinates me and I read everything I get my hands on and would say this I have yet to see it explained as to how it works (other than my primative attemps here and at astronomy daily) Space time does nothing than describe the geometry of circles in square to be cruel. It does not offer any explanation why space is bent near mass...of course I do and fortunately other than wanting a particle to travel at C (impossible) its a good idea
but I can almost fit space time because it is a measurement thing. Mind you I am only competeant in one dimention but that is a math ability thing, I think I understand it.
From what I can tell all the problems (graviton, dark matter neutrenio search etc and even my ideas) for gravity amount to needing a particle to have some mass which is in conflict with it travelling at C. That is all I have really worked out to date and others with pages of notes may take longer to explain the same conclusion I think.
I like the idea that gravity is really the pressure of other bodies upon each other and that any effect we observe as gravity is in effect an imbalance in that pressure caused by a shielding from the absolute pressure of the Universe.
