Does the speed of light vary with the energy-to-mass ratio in the universe?

[JonathanMFreedman]

C = sqrt(E/M)...this would suppose the ratio of the amount of energy vs. the amount of mass in the universe. If not, why not. If there is no mass, just energy, or much less mass at the moment of the hypothetical Big Bang, then, there C would be significantly higher, thus explaining cosmic inflation.

In the context of $E=mc^2$, the $c^2$ is nothing more than a unit conversion factor between units of energy and units of mass. Don't try to read more into it than that.

You might want to take a look at the PF Rules on personal theories. You can't just toss one out and expect us to explain "why not".

The initial post does indeed violate the forum rule about personal theories, so we are closing the thread here.

@Ibix’s point about $c^2$ being just a unit conversion factor is well taken.
