I suggested that you READ. Would you like a reading reference that will 
explain the physical mechanism for what makes a stone drop from your 
hand to the floor, or are you one of the types of people that demands to 
be spoonfed on a newsgroup?

That's not true. Maxwell's equations DO explain how waves propagate in 
space. There are two ways to answer this question, both of which are in 
introductory books. I'll summarize them here.

First way are the physical laws that govern electric and magnetic 
fields. Those are Maxwell equations. What they say is that if you make a 
time-based change in an electric field over HERE right now, then this 
will automatically make a spatial difference between the magnetic field 
over here and the magnetic field over THERE. And vice versa. So if you 
look in detail what happens when those two things play together, you get 
a traveling wave. Covered in all basic freshman physics books that use 
calculus.

Second way to explain it is this. Physicists have learned that observed 
behaviors in real physical systems are tied to the laws of physics 
governing that system. The connection is this. If you can formulate the 
laws of physics in terms of an equation, that equation will have 
solutions. (Solutions are functions, not numbers. If you don't know what 
I'm talking about, then this is where you have to learn some 
mathematical language.) The astonishing part is that every solution you 
find will also be an observed behavior. Find all the solutions, and 
you'll have all the allowable behaviors of that system. In the case of 
Maxwell's laws, it is a very straightforward exercise to put those laws 
in a form that is an equation that every first year student will 
recognize. And the solutions of that equation are waves. Therefore, 
waves are an observed behavior of ANY system that has laws like that. 
Bottom line is this: It's not what's waving that produces the waves. 
It's what the form of the physical laws are that produces the waves. If 
you thought the medium was responsible, you are just flat wrong.

You are wrong if you think waves require material to move back and 
forth. It's just wrong.

That's not what the Doppler  effect is. Doppler effect is when the 
source and the observer are in relative motion, and it doesn't have 
anything to do with how much distance there is between them. (So it's 
not like the further the light goes, the more the frequency shifts.) And 
yes, the Doppler effect is FULLY predicted in Maxwell's theory.

You know this is flat nuts, don't you? Have you read the Nobel lectures 
given by the guys who won the Nobel prize for explaining it? Have you 
even tried?

You've never seen a diagram of the force on a moving charge in a 
magnetic field? Really?
