Lessans said nothing about "strong ignition" or growing in size.
Lessans scenario stated if the Sun, as we know it to be, was newly turned on at noon by God, we would see the Sun at noon. Quit mealy mouthing and weasling.
Is your answer that at noon, light photons are located at the newly turned on Sun and at the retina? If yes, that is two places at the same time. |
I already answered this LadyShea. This is not magic. He was making a distinction between light that has to reach Earth (which takes 8 minutes), and light that does not have to reach Earth before seeing the Sun. |
Right. We know why he laid out the scenario. However he said nothing about light being located on the retina in order to see. He only said we could see the Sun immediately upon it being ignited without needing photons to be located on Earth (indicating he did not think photons need be present at the retina in order to see).
He said nothing at all about light physically interacting with the eyes or camera film or being located at the retina or on camera film.
You have added this physical interaction between light and retina/film. You added it in order to include real time photography in efferent vision, since light MUST physically interact with the film/ccd in order to get a photograph. Since you have added it, you need to explain it. As of right now, you have stated that light is physically located on the retina and on the Sun both at 12:00:00.

That is a given in this scenario, since
Lessans said we would see it immediately. I am not changing Lessans scenario in any way, why are you?

That is not a factor in this scenario, because Lessans said we would see it immediately at 12:00

Yes, this is the scenario. It is large enough and bright enough to be seen at 12:00. If light photons are also on the retina at 12:00, that's two physical locations of light at the same time, 12:00. That's what you are being asked to explain. Did the photons at the retina at 12:00 come from the Sun?
