I am glad for a place like this where I can come to discuss what is on my mind with those interested. My delema is expanding my conceptual understanding of relativity and how it realates to space time and gravity. To begin I will go over how I have come to understand space time contraction. It would seem a frame S observing another moving frame S' will percieve S' frame as contracted in space and time. For simplicity they are both traveling in the x and -x axis direction. Lets say we are in a space craft near the speed of light and we see our selves as normal. However the other frame is moving near the speed of light and is contracted. It has velocity towards us. This suggests to contract it then we would add time to to the front of its frame bringing it closer but the rear of the frame we would recieve even more additional time setting the rear closer to the front of this moving frame. This would contract the observed frame. Of course we would do this using the math of the Lorentz contraction. Then you could consider the far end of the S' frame set further ahead in time symbolizing you traveling into the S' frame future. This would seem to make sense as you would live much longer traveling at near light speed. It also hints at the unseperable relation between space and time. Ok so then we have some one on the ground observing a space craft directly above their head at near the speed of light. It appears contracted but for different reasons. It has forward velocity and appears to be contracted. It having a forward velocity then you subtract time from the front of the craft and add time to the rear of the craft and this contracts it. You can then visualize as the craft travels forward continually subtracting time from it and preserving the occupants life span. This also seems to suggest the connection of space and time but from the S frame perspective. However the contraction in space time dosn't seem to change at constant velocity. This suggests the culprit of space time contraction as being due to acceleration. So then as we accelerate this distortion in space time would seem to contract space and distort time. Ok now lets consider gravity and the earth for instance. If we placed a clock high above the earth at a lower acceleration and another clock at the base of the earth at higher accleration the clocks should be distorted in time and desynchronize due to the contraction of time and space. However for the earth this contraction of time and space would seem to be in all directions. Almost suggesting the flow of time and space into the earth or matter. Or that the future is flowing into a gravitational well. Now this seems to suggest to me matter as possibly being a hole in time and space in which time and space are flowing into it? It would seem to suggest an appropriate naming for the black hole I guess. Or that this suggest gravity is a relativistic effect. I wonder if this would mean that this demands that what is cuasing gravity is a relativitic effect in it self? And that leads to my ultimate question that is assuming that all my other assumptions are correct above. If not let me know. My question being lets now consider matter and down to the atom. What relatistic effect do we know of in the atom that could cause gravity and the distortion of space time. Could it be the differences in between the velocities of the proton and the electron? Is there some other relatistic effect that occurs in the atom that I could not be taking into account? Also are we sure that all mater has the same gravitational constant? For instance does lead have the same gravitational constant as say helium? How would we know this. The closest example I can think of is the Cavendish experiment http://en.wikipedia.org/wiki/Cavendish_experiment I would expect in that experiment we could possibly measure some elements to determine this but here is another problem. How do we know the electron and protons alone have a gravitational atraction? I would think it would be impossible to tell with the electric force being so much greater than the gravitational force. And here is anoteher problem. What if the gravitational force is a result the electrons and protons coming together but the electrons are much faster than the protons. It would certainly explain the 1/r^2 behavior of the gravitational force and the similarity of the electric to the gravity force. But it would have to always be atractive on the other hand. Could the positive proton to the electrons always have a greater aparent charge than the electrons because the protons is what seems to be moving the fastest? And to the protons the electrons always have a greater aparent charge than the protons because they apear to be traveling faster? But for the electrons in orbit around their nucleus there is no change in aparent charge because of the lack of time distortion to objects with velocity perpendicular? Any suggestions where I might be getting lost? I appreciate any ideas on this as I can't seem to get it off my mind.
