That's why I put "zero velocity" in quotes. It is difficult to define what "zero velocity" truly is, so physicist typically use the rest frame of the CMB. As for speed, it doesn't necessarily have to be low to test for Lorentz Invariance. The key is that the test be conducted from a true...

Lorentz Invariance has never truly been tested from a "zero-velocity" reference frame, so we may be moving through a preferred Higgs- or gravity-defined vacuum without knowing it. Like I already said, everything, including Earth, is accelerating at relativistic speeds. Also, we can't test for...

[Mentor Note: Two thread starts merged into one] So what I've been thinking about is how Lorentz Invariance was never proven, it was only assumed to be true. And when I think about the Universe, nothing is actually truly in an inertial reference frame. Everything is accelerating at relativistic...
