Once we thought heaven was just above the clouds, but the moment we got up there, we discovered space.
And as we look out into space we find it is more than we can imagine. It is so big and the speed of light is so slow, that the dream of space ships to other stars is just a dream like heaven.
But the moment we turned the cameras around and looked back at the Earth, we discovered The Environment.
And it is our environment and space is not.
