Light has no shadow

[Diana]

I am thinking, what is the difference between a light source and a non-light source? Does light only 'travel' across a span of non-light source or is every single point ever a potential light source waiting to ignite? My point being that wherever there is light, there is its source. A light radiation is an extension of the body as is your arm to you, it is to the source.

However, I don't believe light actually travels, I believe it is a kinetic potential which is passed from point to point via energy transfer. It's not 'moving', it appears to be moving due to displacement.

When I spoke of the "speed" of light, it was in reference to Einstein's equations. Because the speed of light is constant, it could mean there is no speed or movement at all—it just "is."

So I agree with you in your assessment.
