AI Thread Summary
The discussion centers on the visibility of Skylab's shadow on Earth as captured in a video. It highlights that Skylab orbits at 235 miles above the Earth, while clouds are approximately 5 miles above the surface. The question arises about the size of the shadow observed in the video. Some participants initially interpret the shadow as camera artifacts, while others clarify that the shadow's visibility is affected by the brightness of surrounding clouds and the darker ocean areas, which make the shadow more pronounced. The conversation emphasizes the interplay between light conditions and the visibility of objects in space imagery.

Please ignore the UFO reference and watch for 5 seconds in the below link. One can see the shadow of Skylab on the Earth. Skylab is in a 235 mile orbit above the surface of the Earth. Clouds are about 5 miles above the surface of the Earth. So the camera capturing the images is at least 230 miles from the shadow. Why is the shadow so large?

Camera artifacts? Please explain how that relates to the "shadow" image on the left side of the video.
 
OK, I see it now - some schmaltz on the camera lens. More light from bright clouds drowns it out. Less light from the dark blue oceans make it more visible.
 

Thread 'Could an external cosmic body have influenced Earth’s geology?'

Hello, I’m currently writing a series of essays on Pangaea, continental drift, and Earth’s geological cycles. While working on my research, I’ve come across some inconsistencies in the existing theories — for example, why the main pressure seems to have been concentrated in the northern polar regions. So I’m curious: is there any data or evidence suggesting that an external cosmic body (an asteroid, comet, or another massive object) could have influenced Earth’s geology in the distant...

On August 10, 2025, there was a massive landslide on the eastern side of Tracy Arm fjord. Although some sources mention 1000 ft tsunami, that height represents the run-up on the sides of the fjord. Technically it was a seiche.
