Suppose you are in the same initial frame as the other observer. You with "your" electron and he with his (hers). Keep the electrons isolated (but entangled). Set your and his clock. He moves away in a well defined way. So you can account for time "delay". If he is at rest again wrt you, then you do your measurement of z, and he of x. At a before agreed time. Aren't z and x determined then at the same time?

But what if you measure them at the same time?

Ha! That's ("oooooo-kay") is what my wife says regularly. Only for that an upvote already! Why I react, is because hidden variables "interpretation" (I'm not sure it's an interpretation) says particles have always well defined positions (and thus momenta). I can remember reading that a future experiment could decide between hidden variables and pure chance. Wouldn't present quantum theory had looked different if at Copenhagen it was decided the pilot wave is real? Bye bye many worlds. .. Anyhow. Suppose I measure the spin up direction on one electron and the x component of spin on the other. Wouldn't that mean you know both the spin and its projection, which are normally obeying the uncertainty relation?

How can a field, the Higgs field, have a central maximum (the top of the hat) in energy when the field is zero? Aren't we, by this artificially constructed image, led to the conclusion that the Higgs mechanism is an imaginary mechanism only? With no real existence?

Negative mass/energy solutions are part of the virtual disconnect Feynman diagrams involving one particle "bubbles" in the vacuum. It were exactly these solutions that created the negative curvature of the 4-dimensional substrate on which two 3-dimensional universes banged into existence. The two massless basic quantum fields of nature and the seven gauge fields mediating between them, accelerated away from each other on both sides of the 4-dimensional Planck-sized "throat", or wormhole, connecting two infinite regions of 4-dimensional space. The negative energy of the virtual particle states caused the negative curvature of the initial singularity. Like the curvature on the inside of a torus i.e, around the the mouth of the torus. The two massless basic fields combined to massive quarks and leptons on one side of the open 4-dimensional torus, while on the other side the anti versions banged into being. Dark energy solved. Mass production solved. Matter-antimatter solved (no asymmetry at all). Consequence: Higgs mechanism is a modern-day variant of phlogiston. Extra: anomalous muon g2 no mystery.
