This is my interpretation of propagation of light, proposing the causality extending from present into the past, from the destination to source. I think the light is caused by absorption of it, instead of emission of it, similar to how electricity flow is caused by the consumption of it, instead of by the flick of a switch.

Kindly review and provide your valuable comments. Also please let me know if any of you can endorse its submission to arxive.org. Thank you very much!
