Bold by me.
So you say that the
light is converged by the convex lens and appears there instantaneously:
- How did the light get at the lens when it did not travel there? As you know, light needs time to get somewhere...
- When the light is a the lens, does the light touch the holder of the lens, and can I therefore see the holder?
- If not, how is it possible that the light reaches the lens, but not its holder?
- If the light reaches the holder of the lens at the same moment as it reaches the lens, why does the light around the holder takes 8 minutes to reach the paper?
Further, photosensitive paper reacts because of the
energy of the light. But you say the image of the sun is there immediate. But that is transport of energy, which we know, can never be faster than the speed of light. So you are again contradicting established physics.
