'Emit' is the wrong word, maybe you mean obscure or omit...?

There are eclipses where the shadow of the moon passes across the Earth and also where the shadow of the Earth passes across the moon. I suggest you google 'Eclipse'

hmmmm.........there are infinite stars>>>>>>>>>infinite light sources>>>>>>>why isn't it always 'daylight' ? I'm sure google would come up with an answer..........

OK, this is complicated math but here goes.

If there are infinite stars, that means that for every star, there's another star in front of it. So, the one in front shines, but it now makes a shadow of the one behind. So, if we call shines +1 and shadow -1, and we add them together, whatta we get?

OK, that doesn't seem to work. Try this. Look at Van Gogh's Starry Night. He doesn't show infinite stars; he shows big ones. Now, is that clear?

It's as clear as the sun streaming out of my **** ! I know this little conundram has a good answer, but I just can't recall it, honest.

Shadows are there but not as perceivable as shadows on earth. They do not strike any objects so they are not as visible. Since matter between celestial objects is so sparse there is nothing to show the absence of light being omitted by the object.

Shine a flashlight on a crisp winter night and you can not see the beam of light very well but you can see the light striking the object it is aimed at. Conversely, shine the light on a hot humid foggy night and the beam is extremely visible.

Being that there is not much matter in space surrounding our earth we do not see the shadows very well. But if you are in a mountain range you will see the shadows from one mountain strike another mountain as the sun sets or rises.

Hello Guest,

Here is a picture of an earlier English General - General Ligonier, chosen especially with your Topic in mind.

Note the careful interplay between the light and shadow.

Kind Regards....
