comment Can an observer on Earth only see half of the sky?
"At the Equator, you see pretty much all the sky, if you wait as the Earth keeps spinning around, revealing all the sky to you eventually." by this way the Equator is the only place that observers see the sky in a panorama ? just may you tell me how much the height is effective here too ?
