On occasion I notice there is some talk about "graviton" particles, I would have thought astro/ quantum sciences were past that idea. I am quite aware of a basic rule "Don't fall in love with your theories" so a gravity particle might exist, more on that later. In my understanding of relativity, Einstein doesn't prove or disprove Newton's laws, but he pointed out that the laws were limited to the restrictive "special" theory. This also leads to the concept of gravity as an "apparent" field, and in this sense Newton was confined due to the limited technology of his time, as well as his reference body seemed to be at rest. it is easy to see how gravity would have shown signs of it being similar to electro/ magnetism. One problematic issue of the field theory, is that magnets attract certain metals, but not wood, stones or other materials. Gravity does not discriminate. it would also occur to me that the massiveness of our sun would generate a field (no matter how weak) that should be large enough to attract the inner planets directly into the sun itself. Also if a gravitational field similar to electro-magnetism should not be conducive to the creation of orbit, orbit gives the impression that there is a struggle between an attractive and repulsive forces at work simultaneously. A curved and warped continuum could create those circumstance I think a more accurate consideration is that a plastic and pliable universe might cause gravitation independent of a fields. in my opening paragraph I stated there is a chance of gravity particles, so looking at the opposite side of this matter. The monkey wrench of dark matter/ energy thrown into this mix, resurrects a particle theory and might give an optional outlook other than curvature. The indirect proof of dark matter/ energy can be seen in the case of cosmic lensing. To that end the phenomenon of barely detectable substance, that has no mass or interaction with other particles but creates gravity, gives way to see a probable "graviton" from a fresh point of view. finally there is a point and a question to my rambling. Could dark matter/ energy be the missing gravitation particle? Or are these W.I.M.P. ('s) the basic substance of space that appears to be empty?
