This is just demonstrably wrong. How many times do you need to see the Hubble Deep Field Image? Do I need to post it again? Do I need to explain yet again that the point in space that Hubble was directed at for over a million minutes appeared empty when seen through a telescope or camera lens? Nothing could be "seen through the lens" at all. |
I also said that this actually may not contradict efferent vision at all. We all know light travels and we all know that if it hasn't arrived, it will be dark. The Hubble Telescope allowed us to see galaxies that traveled through space/time. |
What are you talking about? This is word salad.
The light has arrived and continues to arrive from those galaxies, but must be collected by a sensor over very long periods of time because it is so faint. Our eyes cannot do this, but the Hubble can. Therefore they don't work the same way.

It also would take 8 minutes for us to see light coming from the Sun if it was just turned on, because it's not here yet. When I talk about efferent vision, I am referring to detecting matter, not just light.

If we have to wait for the photons to arrive to see the light, then we would have to wait 8 minutes for the light to arrive for the camera to utilize the light to create an image. Therefore, even if Lessans were right, and we could SEE the newly ignited Sun at noon with our brains looking through our eyes, we couldn't photograph it. Cameras require light photons to be "here" (wherever the camera is).

I'm sure that's true with advanced technology using heat. I am referring specifically to the visual spectrum and what we are normally capable of seeing through a telescope, camera, or eye.

These cameras use infrared
light. Infrared works the same as all light does. So, if a camera can detect the object, but the eyes cannot, they don't, in fact, work the same way...correct?
