Photographer's Note

as far as I'm concerned, one of the major events during the 20th century was understanding that not only Earth is not the center of the Universe, not only our solar system is not the center of the Universe, but that even our galaxy, Milky Way, is nothing to write home about, it is one of approximately 170 billion galaxies in the observable universe. and even if that was not enough, cosmologists have come to believe that on a large enough (200 million light years) scale the Universe is homogeneous, meaning it's the same at all locations. like water - to us it looks very even, although we know it is made of molecules and smaller particles. same with the Universe - if there was a giant looking at the Universe at the same scale we look at the water, it would look very even.

I am writing all this to come to what this cosmological principle means emotionally. very simple - no matter how far we travel, we'll find exactly the kind of Universe we find close to home; we find home everywhere, we are "at home in the Universe". I though this an appropriate message for my 200th post.
