was wondering what set c to its speed ?
was wondering what you really masgrgdffh ?
Lol. Did you fall asleep on your keyboard before finishing that sentence?
And Bozo, c is the speed of light.
"was wondering what set c to its speed ?"
from what i can interpret from that badly written question, he wants to know what exactly sets a photons speed to C and not to any other velocity.
No, but I wanted to be about as coherent as Bozo.
The electrical and magnetic properties of the vacuum set the value of c, according to the Maxwell equations.
As a follow-up to what selfAdjoint wrote, is there any hope that string theory will help answer why "the electrical and magnetic properties of the vacuum set the value of c"?
My guess: probably not. ST will probably set out a range of possible values for c, or outline equations which will function if c is a certain value, or whatever. But I doubt it would mathematically define c to be a specific value as a matter of neccessity.
I don't think c is just set by magnetic properties of the vacuum, and so on. I think that c is a specific property set by the geometry of our particular spacetime, and that the permeability/permitivity constants are effects, rather than causes. But then again, I don't really know.
