Many people say the 1st images shown look like totally fake CGI. It looks like that to me, also.

I have a love of history and really like seeing it, if you don't learn from it, you are likely to do wrong things all over again. This history is out of our hands, yet interesting to see. If it doesn't show people how really small we are in the real view it shows then we just don't really comprehend ourselves as people. I'm glad the "center of the universe" outlook has been dispelled from our beliefs but, I feel sorry for the people that have dedicated their lives to show something we all know to be true if you have a mind to yourself and understand the true way of our life through just faith alone. It only proves that focusing on a grain of sand in the sky is much deeper than we already know. The marvels are not worth the expenditure of money that takes away from things we should be doing. Not socialism, just setting up world that all can prosper in without overpowering old way thinking dictators wanting to rule. You know the answer in your soul, try turning that way, but know that Love rules above all else and don't give into thinking you can correct something all encompassing, because you can't on your own.

No avia que hacer un telescope que cuesta million dollars, con tan solo mirar una gota de agua en una hoja en una noche obscura puedes descubrir el universo.
