Can you derive the speed of light from non-electromagnetic constants?
In the nineteenth century, James Clerk Maxwell discovered that the electrical permittivity times the magnetic permeability of space = 1/speed of light^2, which makes sense because light consists of electric and magnetic field disturbances. But some non-electromagnetic entities travel at the speed of light too. Like neutrinos, which are a weak force phenomenon, and gravity waves which of course are a gravitational field disturbance. Can you derive c from weak force or gravitational constants?

there are 3 fundamental constants we know of c, h(h-bar), and G(newton's constant). each of them derived from the respective theories. using dimensional analysis, im sure you could construct some equations with h and G to equal c, but it wouldn't be derived from any equations from the theories of GR or quantum mechanics. the fact that the constants appear in each of the theories is due to the fact that GR and QM both take some results from Electromagnetic theory

A photon is massless. that could be a sort of capability. In relativity capability and mass are equivalent. this means that an merchandise with greater capability has greater mass and for this reason greater gravity. This varies based the place you're. case in point, if the Earth exchange into passing you at a million/2 the value of light it would look greater vast to you than to me right here in the international. As v will enhance, its relax mass (what you degree on a scale) keeps to be a similar. regardless of the shown fact that, its relativistic mass (what supplies it gravity) will enhance
