However, in some cases, no matter how healthy an old paradigm appears to be, it may still need replacing by a new one, when newer knowledge presents itself. |
Amen!
Einstein may well be perfectly correct in SR & GR, yet insufficiently complete at the same time (He knew this too). I feel one day this will show to be the case, that relativity can be built upon.
Example:
“The wave function does not in any way describe a state which could be that of a single system; it relates rather to many systems, to an 'ensemble of systems' in the sense of statistical mechanics”
- Albert Einstein, 1936 -
You could easily assume that each particle type had its own Metric Tensor field (like Einstein's Tensor in GR), and layered into spacetime, these fields somehow interact with each other through an overarching field. Then just as the Einstein's Tensor and Energy Momentum Tensor relate directly to each other, there's a direct connectedness to everything...no need for unification!
And before the hot-heads start shaking their fists, it's just an example to demonstrate my point, I'm not saying it's real.
