Light as a Potential Field

by on Mar.24, 2010, under thoughts

Last night, a friend of mine proposed an interesting way to think about light. Although, it wasn’t until later that I actually understood what he was proposing. When he said it, I really wasn’t sure what he meant. Let me first try to describe the idea as it was described to me:

Imagine that light is neither a particle nor a wave. Instead, we only see light because there is a potential path for light to travel between whatever object we’re looking at, and our eyes. So then, what is dark? Dark is the impossibility of light.

Now, I had a couple problems with this. First off, if this is the case, then where does the light come from? The only answer I was given was basically “we don’t know”. But, I think I’ve solved the puzzle that is this proposition. Again, let’s imagine that light is neither a particle nor a wave. Instead, think of light as a field of potential. If you don’t know what a potential field is, think about gravity or voltage. We can describe both of these as a type of potential, and observe the potential compared to other places in the field. These fields are not local fields, they are everywhere, but they are very weak away form the sources. (continue reading…)
