either you must not know a lot of scientists or there are not many scientist that you would consider serious scientist. studying the skys, as well as almost every other science (i cant think of any that dont), leads to better understanding of earth. few sciences dont aid our understanding of our planet, or ourselfs. If nothing else, it helps us to understand why we have a drive to go there. why else would they study photos hours on end, knowing that few would ever know what they are doing, and even fewer would understand if they did.

as far as the rest, thank you for noticing how valueable it is.

of course since you did not write it, you dont believe it has any value at all. no one but you can write any truths, :rolleyes: can they?

the more man learns, the more he realises, he really does not know anything.
