I've got MATLAB set to several(about 20) decimal places and I noticed something. G^(E0M0)=1 seemingly exactly. That is the gravitational constant G raised to the quantity of the permittivity constant multiplied by the constant of permeability. That is approximately (6.67428E-11)^((1.2566370614359E-6)*(8.854187815E-12))=1.0000000000. Now obviously I know that that doesn't necessarily mean anything because the numbers are so small, but has anyone ever noticed it or commented on it or at least investigated it? Keep in mind that those are just approximations for the physical constants.
