When we look out into space, we’re looking back in time; the light from a galaxy a billion light-years away, for instance, will take a billion years to reach us. It’s an amazing thing. The history is there for us to see. It’s not mushed up like the geologic record of Earth. You can just see it exactly as it was. — Margaret Geller
