    ...the speed of light was the same as the speed of sound?

    Would the Universe still be able to function?

    Is the speed of Light is 186,000 miles/second for a reason?

    there are two alternatives:
    1)there's some physical reason and we haven't discovered it
    2)Because the maths say it to be that way

    I'm inclined to choose option 2

    Yeah,

    But I suppose that Maths could say it was like that, however whose it to say that Maths is the way it is, because of the Speed of Light, and how the universe is composed?

    Erm, why would the universe suddenly stop working?
    Light travels faster than sound because they are different wave types, and so have different frequencies, and so one travels fatser than the other.

    yeah, sound cant travel as fast as light, you simply can’t make a sound wave propagate that quickly. The speed of sound in a medium can be determined by the equation v = v = (B/p)^1/2 Where v is the speed of sound, B is the bulk modulus of elasticity, and p (rho) is the density.

    as for the speed of light being what it is, I am going with alternative 1. the "maths" do not really tell us what c should be, but rather we can measure it and compare everything with it. like f=c/lambda. we find c experimentally.
