I’ve been shooting and posting on YouTube, my footage of the multiple celestial objects, what I’m calling suns for now. I have been frustrated by the clouds frequently.
This past week, I found myself asking the question…
Why are clouds illuminated from below during sunrise and sunset?
I think it didn’t occur to me before that this was strange because it seems that the sun is below the clouds. Seems. Assuming a spheroid shaped Earth, the sun is actually never below the clouds.
Even when it is appearing to set, the rays should strike the clouds from above, right?
Think about it this way, if I had a superstrong light beam, and I situated myself just above the clouds, I would be able to shine the beam of light on the underside of some clouds that are distant from me from an oblique angle. They’d have to be farther away because I would be exploiting the curvature of the Earth.
Now, if I move higher still, the number of clouds I could illuminate from below decreases. And if I move higher still, there would be a position from which I could illuminate perhaps the side but not the bottom of any clouds.
This would be consistent with why a satellite can only take a picture from directly above (or nearly directly above) the subject. Can a satellite take a picture of the underside of the cloud? No. The satellite requires direct line of sight, light travels the same way. (Edit: this may help explain that concept… https://www.youtube.com/watch?v=v3YpiFCGZRY)
Is there anyway to photograph the underside of a cloud from the moon? How about from the distance of the sun? Even if it were possible, wouldn’t we see the shadows of interposed objects between the sun and the bottom of the clouds?
Something is strange here… because even if you dismiss the points mentioned above, we have to remember that it isn’t just that the clouds are lit from the bottom, During sunrise and sunset the rays of the sun point upward through cloud cover.
How can this be?
