Many of the principles of logic would disappear also.
It may not be my place to say this, since I'm not a physicist, but stuff like this can only come from an overeducated pinhead...
With planar time causality goes away. Cosmologists know this and it has been around a long time unless time is planar in which case it’s hard to say.
Hey, don’t hold back, tell us what you *really* think. ;’)
“time” is nothing more than over running matter waves, in newtons of wave Force. Visualize a surf wave slamming into a seawall, that’s what happens as a h by h movie at the quantum level, referred to as the “collapse of the wavefunction”. But these esoteric pinheads will never get THAT, it’s too SIMPLE, and too SIMPLE = funding dries up for their string theory ballerina dance...
All this joker is talking about : two time dimensions, is nothing more than Particle velocity and matter wavelength(dPv and dWs), the REAL determinants in the HUP. “delta momentum” is an oxymoron, as is “rest mass”.
