Consider Only General Relativity

Every old style, Newtonian theory in modern physics – which is all of them except General Relativity, do not fit well with GR itself. This is curious, as for instance the Dirac equation, the Standard Model, QM, QFT all work well with each other (hence the Standard Model). In an attempt to unify everything else with GR, the well worn (almost proven impossible by now one would think) trail is to quantize GR on some perturbed Minkowski space.

It doesn’t work. Or rather has not worked.

Since it’s virtually impossible to prove that something can’t be done in physics (see von Neuman’s ‘no hidden variables proof’ as an example), we are left with hundreds of PhDs per year being granted trying to add another brick to a wall that is sinking in mud, hoping that the mud is only so deep, so that another few thousand postdocs life efforts piled up will hit the rock bottom.

It won’t. It’s pure folly.

An alternative is what I present on this site, namely that one can and indeed must build on General Relativity – that in a very real sense all future successful theories will be phenomena inside the Riemannian manifold controlled by the Einstein Equations that we live in.

Examples provided on this site show how one can make electric fields, quantum waves and particles from nothing more than GR. Of course, it’s a minority viewpoint, one I’m willing to stand on.

In this essay I argue for the case of simply trying, in the sense of a toy model, to build parts of the universe out of nothing more than 4D, standard Einstein General Relativity. Its already the norm for a postdoc to spend a decade looking at some 2D toy model of a field that is known not to be able to work, just because it’s easier to do some calculations.

But apparently doing the same thing with a model (4D GR) that we know works extremely well is, well wrong, boring and silly.

I don’t think so.

Physics needs new trial balloons. To the fundamental physics establishment – you can’t actually pop a balloon unless you at least get it in front of you.
