Amazing. Thanks giddy. Reminds me of an exercise that Larry Bird used to do to improve his concentration. He would picture, in his mind, being in outer space above the earth and then slowly visualize coming down to the room he was in in his house. He was able to do it for hours at a time. Much like meditation.
How in the world do we know what the Milky Way looks like from 10 million light years away from Earth when we have nothing out that far to see it?
