similar question. when it is night for one side of the planet, how come we do not see like a tunnel of light when we look in the sky? the earth blocks a section of light from the sun, but how come we cant see that light passing around the earth?

I am not a physicist or something but still interested to know things which are not clear. Learned people’s efforts to give knowledge to the mankind is very much appreciated. Some Answers to Oblers’ paradox , to me , is very complicated to understand….. My argument is … from the surface of the moon, which is far from earth only 380,000 km, why sky is always dark – day and night ? and they say it is due to lack of atmosphere, as I understand. And also why the side of earth which is facing the sun its sky is fully bright and other side ( night time ) the sky is fully dark? why we can not see glow or brightness at night of other side of the earth’s sky facing the sun ? which is only 12,000 km away from us while we can see light from stars which are away from earth trillion of kilometers? please could somebody explain this to me if my question is making sense to you. Thank you.

we live in south africa do we see the same galaxies every night and what would our daylight galaxy look like (say for eg we could switch of the light during our daylight what would we see)
