Looking on Lightyears by Rob Rey - robreyfineart.com
The deeper we look into space, the deeper we are looking back in time! Light travels an astonishing 9.461 trillion kilometers in one Earth year. Yet the depths of visible space are so vast that we can see light arriving at earth now that left it's source 13.8 billion years ago, near the beginning of time (red shifted as it may be). All the light arriving from in between there and here is a history of the universe, waiting for us to learn from. We may not be able to change the past, but we can peer deep into it's chronology.
