Comment on Hummingbird feet
HonoraryMancunian@lemmy.world 10 months agoFun fact: next time you see the moon in the day, study the angle of the sunlight hitting it — it doesn’t appear to line up with the sun. This is a perspective trick based on the fact the sun is way further away than the moon yet we perceive them the same distance. And no I cannot intuitively grasp this.

It has to do with apparent size of the sun and moon. The sun is 400 times wider than the moon and coincidentally 400 times further away, so they look the same size. With no other reference points as to how big each object thing is, we perceive them to be the same distance.

That bit I can at least fully comprehend. It’s the sunlight angle thing I can’t wrap my head around.
