Quote by elfmotat 					 				 				When solving this equation, he found that EM waves travel at a speed given by:  $v=\frac{1}{\sqrt{\mu_0 \epsilon _0}}$  , where μ0 and ε0 are the magnetic and electric constants.
Correct me if I'm wrong, but as I understand it, μ0 and ε0 are entities of the EM field only. This does not leave much room for confidence that other fields would propagate at a maximum speed of light.
