A simplification is the continuous version of Maxwell's Theory. Much simpler to treat the dielectric in a capacitor as a continuous substance than a bunch of individual atoms... >>There are no atoms in "MACROSCOPIC" theory. >One could say that "NO ATOMS" is > what "MACROSCOPIC" means eh! Which is why the macroscopic version isn't valid for a very sparse vacuum, where the distance between atoms is large compared to wavelength. In such a case, the light really does travel through a perfect vacuum between encounters with the odd gas molecule. >The "density" at every point throughout ALL SPACE, >will have a FINITE,non zero ,value, And a finite, zero value between atoms, for light with short enough wavelength. Tom's point was that a physical medium such as interstellar gas just gets in the way of the light, slowing it slightly. You want to argue that interstellar gas is continuous for radio waves? Fine, an excellent model. You want to argue that interstellar gas is continuous for X-rays? Sorry, not valid.
