After you've read Norton, then tell me whether you think it is "the

Z.

Easy I don't have to read Norton for that.

It's OBVIOUSLY DYNAMICAL.

Local gauging of T4 IS Diff(4)! The compensating B field that gives REAL
TIDAL WARPS is as real at the EM field!

Looking for a wider covariance group is SAME THING as LOCAL GAUGING!

Any nonlinear GCT when B = 0 is simply SIMULATED GRAVITY in sense of
Landau & Lif****z Ch 10 Classical Theory of Fields.

Also the SPIN 1 Yang-Mills B field is t'Hooft renormalizable if you
quantize it when SPIN 2 guv is NOT!

It's same as Fermi 4-spinor vs. SU(2) W mesons.

This is another reason to reject PV as a waste of time. PV has no
tensors, no GCT, it's much too simplistic and primitive. It's Mickey
Mouse Sorceror's Apprentice physics.

Interestingly, I personally heard Greene say, "there is an ether".

We all say it. But it's a Diff(4) covariant ether.
