And number 3 hahah
I know you think you're right, but you don't have to be a dick.
"The only barrier to truth is the presumption that you already have it."
If a solar eclipse causes the moon's umbra to be about 100mi wide on earth, why doesn't the same thing happen to earth's shadow on the moon in a lunar eclipse? The earth's shadow completely covers the moon - and then some - meaning it doesn't even shrink to 25% of it's original size whereas the moon's shadow is about 5% of it's original size. How do you explain that when the light source and distance are basically the same?
