Vacuums are, depending on how one looks at them, either very lonely or suicidal. They are constantly trying to pull things in to end their existence as a vacuum. And, there is always something trying to force it's way in to oblige.
My thoughts on that have always been that, if outer space is, indeed, a vacuum, then that would mean that there is something REEEEALLY BIG trying to get in. :(

the light of the star inside the atmosphere is differ outside of it


maybe there are another planets in eath,s solar system but we cannot see it because its to big
