The discussion revolves around the relationship between relativity and Newtonian physics, exploring how these two frameworks interact, their limitations, and the potential for reconciling them. Participants examine the implications of General Relativity (GR) on Newtonian concepts, particularly in the context of gravity and motion, while also considering speculative ideas about the nature of particles and gravitational effects.
Participants express a range of views on the compatibility of Newtonian physics and relativity, with some agreeing on the incompleteness of Newtonian gravity while others propose different mechanisms and interpretations. The discussion remains unresolved with multiple competing perspectives on the nature of gravity and particle interactions.
Participants acknowledge limitations in their discussions, such as the dependence on specific conditions (e.g., low velocities) for reducing relativistic expressions to classical forms. There are also unresolved questions regarding the mechanisms of gravity and the implications of quantum effects.
General_Relativity19 said:I read in a book that relativity and Newtonian physics don't work with each other or something like that. Like when Einstein founded Relativity, Newtonian physics were partialy disregarded because Newtonian physics didn't account for relativity. Can Newtonian physics be like converted to work with relativity?
Too true! One thing sorely lacking in GR is a mechanism for gravity and inertia. Mediating particles like gravitons and Higgs bosons have been postulated, making the model more cumbersome and speculative.Chronos said:Newtonian gravity was never wrong, just incomplete. Physicists already knew that before GR came along. GR basically just adds a correction to compensate for relative motion. But, then again, no one is claiming that GR is the final solution either. Most physicist think the chances are good that GR is just another stop along the way toward an even more complete theory [hopefully one that will allow it to coexist with Quantum Theory].
I've wonder if particle are extended vibrating objects, then wouldn't their spatial properties and frequence be effected by strong gravitational fields? For example, the frequence would be slower near massive objects wouldn't it?turbo-1 said:If a mechanism can be modeled that either densifies or polarizes the ZPE EM field in the presence of mass, lots of GR's problems can be solved simultaneously. These include anomalous galaxy rotation curves, excess cluster lensing, and excess cluster gravitational binding.
However, these frequency and spatial distortion would have the same effect on all particles interacting at a particular stop. It would not be as if a distorted particle were interacting with non-distorted particles. All particle would be equally distorted at the point of interaction. So the interaction would not be affected by the distorting effects of gravity. I suppose the only exception would be if the gravity were so great that it gave tidal effects on the scale of a string. This would seem to prove that particle interactions are unaffected by gravitational fields, or should I say by the background metric. Does this sound right?
