Absolutely K626, in the 4D Minkowski spacetime. All postulates of the Relativities are elementary and fundamental in the higher dimensional cosmologies.

However the de Broglie Phasevelocity can easily be used to define the superposition of the scaled distance parameter R(n)=V(n)/F as a rescaling of the lightspeed invariance in Lightpath X=cT=c/F.


Phasespeed VdB=(wavelength)(frequency)=(h/mVgroup)(mc^2/h)=c^2/Vgroup > c for all Vgroup < c.

The lightspeed constancy in higher D membrane space so becomes a lower tachyonic limit for the phase speed, just as the lightspeed c is an upper limit for the lower D Minkowski metric (measuring a group-velocity Vgroup as a vector bundle).

As said, a 4D technology cannot mechanistically 'overcome' the restriction of the Relativity physics of Albert Einstein.
