Einstein's theory is wrong on many counts. One of them is the very basic fact that the speed of light in a vacuum is the highest and is constant. The fact is, it is not constant but varies within some range even in a vacuum free of any major gravity (well light carries electricity and magnetism as it travels and photons should carry gravity too, albeit small) . Why should it be constant when everything else changes? I think one aspect of spending money and resources on space and astronomy is the economics itself -- it creates a chain reaction of job creations on the basis of a little hoho and haha with echoes of wa wa and ga ga. Now one of the real reasons is the abstraction of findings in space for use on the Earth. Another minor reason is , as you know, because it is there and you cannot always sit back and masterbate if you do not have a girlfriend or keep on measuring the width of the ole vagina if you have one, but not a new one, all the time. On the side note, no matter how much money you give to certain beggars and lazy asses, it would not make them live better; they'd better keep the money under the ground till they die and not use them rather than move their ass and think high. To sum up, jhan bujyo jhan gaaro ... so that younger round asses get excited over overlooks left by the predecessors. Chill out
