The c=h/=G=1 - question

TL;DR

This paper explores whether fundamental constants c, h/, and G can be set to one, concluding that their invariance is not merely a matter of units and can be achieved through suitable formulations of physics.

Contribution

It demonstrates that classical space-time and quantum mechanics can be formulated with these constants as truly equal to one without arbitrary unit choices.

Findings

Constants c and h/ can be set to one through proper formulations.

The issue is not solely about unit selection.

Classical and quantum physics can be expressed with these invariants as true unity.

Abstract

The question whether the invariant speed c, Planck constant h/, and gravitational constant G can be or should be put equal to 1 is analyzed. The discussion is based on fundamental considerations concerning the notion of physical quantity. It is found that the issue is not a matter of appropriate unit selection. Further it is shown that classical space-time geometry and quantum mechanics can be formulated in such a way that the invariant speed and the action quantum are truly one and do not have to be set equal to one.
