So the spring would move the same way it did before, and there would be no experimental or observational way to determine that anything had changed. Just as in the case of the gravitational constant g, the Coulomb electric force constant in a vacuum ε0, and the magnetic constant μ0 (also called the vacuum permeability of free space), would also produce the same value today that it did yesterday when we find those numbers through experiment, and for the same reason it did for the gravitational constant. The speed of light c would be the same too because from Maxwell's Equations we know that c = 1/√μ0εo. Thus physics textbooks would not have to be rewritten in any universe.
