I'm standing on the Sun. I'm holding the toy car from our science experiment. Imagine the car is acting as electromagnetic radiation leaving the Sun. I've tied to the car one end of a reel of ticker-tape. I'm going to throw the car down to planet Earth. The ticker-tape is passing through the stamping machine. The machine stamps a dot once per second. At first the dots are close together, but as the velocity of the car increases, the dots grow further and further apart. The dots become less frequent. The car is travelling at lower and lower frequencies.
The car is electromagnetic radiation. It is light. It is the speed of light. As the velocity increases ever faster and faster, what is there to restrict its speed? The potential energy of the car is being unravelled into kinetic energy. This little car is getting faster and faster. By the time it reaches the planet, the car is travelling at an incredibly low frequency - but just imagine how much energy it's packing. With nothing to restrict its speed, the car can travel faster than the assumed speed of light (300,000 km/s). Hell, if the frequency was low enough it could make the journey instantaneously.
So what determines the velocity at which the car falls? We could say gravity, but I'm afraid there's no such thing as gravity in my Universe. In an electrical circuit the current is the velocity. The source injects energy while the load extracts it. If you increase the load - you increase the current, and so you increase the velocity of the electromagnetic energy. The Sun is our energy source. It has to be creating an extremely high voltage to seperate the charges. The Earth then is the load. Do we all live on some kind of cosmic light bulb? Or better yet, a cosmic motor?
