The <i>value</i> for the speed of light in space was fixed a few years ago.<br />As far as I know light-speed, C, hasn't been measured outside the solar system.<br />This value is apparently now mandated for the entire Universe without proof maybe.<br />I tried a topic on C being fixed or the value constant but didn't get an answer I understood.<br />C can no longer be measured only the time it takes to travel a distance or the distance it travels in a time.<br />It does seem that if C was measured to be of a different value, in say another part of the Universe, then either time or distance has varied <i>not</i> C.<br />Hasn't this locked us into a dead-end by discounting a different value or perhaps speed of C.<br />Surely Maxwell showed C to be a product of the <i>properties</i> of space i.e. permeability & permittivity so fixing C has fixed these for all space.<br />velocity(light)^2 = 1/ (permittivity * permeability)<br />He also calculated the value of C didn't vary with with relative speed, shown later by the experiment of M & M.<br />Is our parochial view assuming all is the same everywhere stopping us taking a different view & locked us into a dead-end.
