Rhetorical Question: I have never understood why light (primarily a form of information or data) is often assumed to have velocity. We would never in any other process, attempt to give the quality/definition of speed to any other form of information and rather look to the platform or mechanism. Did we just assume light could travel on its own, without ever considering that there was some other entity involved? And just to round off this 'devil's advocate' opener; what would light truly be to us in scientific terms, if we were a highly evolved race of Earthworms i.e. blind by nature?
