Neat little thought experiment. I was pondering what 4 D light would be like. This describes one particular aspect of it:
"Four dimensional shadows
I went for a walk to consider all this and walked literally into a four dimensional ‘thing’: my shadow. Walk with me for a moment and you might just get an intellectual glimpse of the fourth dimension.
When you walk past a lamp post at night then as you walk away from it, your shadow will grow longer and longer. When you walk towards it, the shadow behind you will get shorter. The shadow itself is like a cutout of your profile and depending on whether you walk away or just past the light, your profile may be frontal or a side view, or somewhere in between.
Imagine that you stay put and that there is more than one lamp post around you. Each one will throw your profile as a different shadow at a different place on the street. Now imagine that there infinitely many light points all around you at any distance or direction possible. Light points everywhere. Now, each one will throw your profile as a shadow at different places on the street. Infinitely many shadows in infinitely many places. Although they all overlap and you can’t really see one from the other, they are there all right. Each one is there, each one distinct. Infinitely many all at the same time. If you want to think a little deeper, you will realize that each shadow is like a dark cone that projects from your body, with one of the light sources at its apex.
All those shadows are really just reflections of your body cast from an omniscient light source. All together these shadows are a four dimensional thing. As you stand there in that omniscient light, you are casting a four dimensional shadow that is all around you.
Can you imagine such a hyper shadow? Can you imagine that fourth dimensional thing? Perhaps you can…"
