Lorentz Symmetry Violation

Recommended Posts

After a quick scan I'm having trouble reconciling "approximately inertial" and "tiny Lorentz violation". One needs to show that the approximations are not responsible for the apparent paradox.

 

It's a thought experiment, which leads me to think that this is simply a mathematical problem from not treating it with sufficient rigor.

Currently Lorentz symmetries are hot topics for many researchers, and many sensitive experiments are being constructed to find violations by e.g. looking at quantities called coefficients for Lorentz violation, if coefficients disappear completely then there wouldn’t be any violations else tiny violations might be found. As regards approximately initial, for instance as earth rotates and spins still experiments can be performed as they would be in inertial system.

 

Without considering too much technical details, as regards math for this paradox, simply consider Lorentz transformation for two inertial systems that move in parallel with same speed would simply become Galilean transformations, as theirs relative velocity will be zero and γ (Lorentz contraction factor) becomes 1, which is shown in the article.

Only as an approximation. At the appropriate level of precision, there will be deviations from special relativity. This must be taken into consideration when looking for violations of Lorentz symmetry.

Better go into some of those details.

 

What are "two inertial systems that move in parallel with same speed" ? Same speed with respect to what ? Parallel to what ?

 

Do you mean two inertial reference frames that are stationary with respect to one another, with parallel coordinate axes ? If so the transformation is simply translation. The two frames are simply choices of an origin for parallel axes s in a single affine space. This case is utterly trivial.
