Wormy assertion is not a valid arguement. Every inertial observer adopt the laws of physics of the absolute frame and that's why all inertial frame hav ethe same laws of physics.

The laws of physics of the absolute frame is adopted by every inertial observer an dthat's why all inertial frame have the same laws of physics. - Hide quoted text - > > - Show quoted text -

In case it's a typo....of there is no longer a need for an absolute frame after every inertial observer claims the exclusive properties of an absolute frame.
