There's a Chinese idiom that goes

"Viewing the Sky from the Bottom of a Well".

It's meant to express when someone is ignorant of the world around them. All they see is a small patch of sky, but to them it's everything.

This picture reminded me of that, and the immensity of the world around us. What we see, and what we don't.
