Without making your head explode - imagine an ambulance is emitting a wave. The wave itself is uniform in all directions. The ambulance, however, is moving toward you - and so the point of emanation for the wave is piling up on itself, making the waves ahead tighter, and making the waves behind looser.
Just like if I walked toward you making waves in a pool. If I push a ball down into the water every second while stationary, you'll see the uniform wave. If I push the ball down every second while moving forward a foot every second, you'll see the leading edge pile up and the trailing edge spread out.

I forsake not, my country, my mission, my comrades, my sacred duty. I am relentless. I am always there, now and forever. I AM THE INFANTRY! FOLLOW ME!
