If we see instantly as per Lessans, if efferent vision were true, we would be able to see a supernova much, much, much sooner than we could detect the light photons from that supernova. Decades at minimum.
That doesn't happen. |
Like I said, we have to do experiments on Earth before coming to conclusions about outer space. No one has yet answered my question: Why are we able to get an image of someone when their physical being is in our field of view, yet we cannot get an image when their physical being steps out of view. According to the afferent model, the light bouncing off of that individual would allow us to see that person. But this never ever happens. You can't use the inverse square law here, and you can't use the fact that light travels too fast because if that was the case we wouldn't be able to see the person when he is closer to us.
