Why sin waves and not just straight beams?

    Light does move in a straight line. It does not follow a sin wave path!

    The electric and magnetic fields that makeup light get stronger and weaker in a cycle pattern. A graph of the strength of these fields as the light moves past you looks like a sin wave. But there is nothing actually moving thru space in a snakelike path.

    This question takes one back to the time of Creation of our Universe.

    Linear forces (the straight beams) in our Cosmos existed in the Event Horizon, where it took just a very small fraction of a second for energy to come to a focus to the point of an explosion that some scientists believe happened 15 billion years ago and caused the universe to begin to exist.

    Unlike the cosmos, forces in our universe follow Newton's first law that every action has an equal and opposite reaction, so forces in the vacuum of space are not linear but exist as force fields and magnetic turbulences.

    So --- No 'straight beams' in our universe. Light undergoes rectilinear propagation at 'c' with transverse sine electric fields and consequent magnetic fields,
