The earth is rotating bro. It is not static. that’s literally why there are jets streams and prevailing wind patterns. If you could actually use a rotating body as a static reference frame, the stars in the sky would be spinning around your reference frame every 24 hours. Any star doesn’t have to be very far away before it needs to move faster than the speed of light to complete it’s rotation (which is not possible). Go spin a basketball. I promise you the 2 sides are moving in opposite directions from any reference frame that is not spinning (bc reference frames by definition are not spinning)
This is what gets me confused. If we’re at the top, I see the banister mount turning horizontal, not up. Up from that POV would be towards the viewer, but it’s angled away which would be horizontal. We have to be looking from the bottom for it to be turning up in this photo. I have no idea how hundreds of people look at that and say it’s turning up.E: nevermind, the question asked where the mattress is, not where I am looking from. 🤣
