From Nat's blog ...

It takes sunlight eight minutes to reach the earth. We never actually see the sunlight of the present, only that of the past.
Staring into the evening skies, we can gaze upon a star that scientists will tell you no longer exists, a star that went extinct ten million years ago.
Both are points made by Thich Nhat Hanh. Both cause one to stop and think for a moment what our perception is and how subject to influence it is. The observer and the observed are essentially one and the same because we inter-are. We are a part of what we are observing: If we do not exist, then nothing exists, the subject and the object are part of each other.
