Re: "How Does Light 'Know' How Fast to Travel?"

It does not alter the fact that mathematically an observer who always
sees light propagation every which way at the same speed is in classical
terms stationary w.r.t the notional propagating medium. Put simply if
you are hovering over a lake in a balloon and you drop a stone into the
lake then if you remain at the centre of the expanding circle you are
stationary w.r.t the lake. If it will put you in your comfort zone then
we are talking about a wave model of light in which the observer is
mathematically equivalent to being stationary w.r.t the propagation
medium.


The observer co-moving with the light source measures that the waves from
his omni directional transmitting antenna travel outward in all directions
at c, regardless of his velocity.

An observer in a different inertial Frame of Reference measures the waves
from the moving source as moving at c in this observers iFoR, BUT he does
NOT see the waves distributed equally in all directions from the moving
source. As he passes the source he will notice the wavelength changing. It
is called 'Doppler shift'.
