Where wast thou when I laid the foundations of the earth? declare, if thou hast understanding.
Job 38:4
"...until you realize that if the entire universe were made symmetric, 
then
all of the good features (e.g., you) are decidedly asymmetric lumps that
ruin the otherwise perfect beauty of the cosmos.
.....The laws of physics seem to act equally in all directions. This is one
of the great symmetries of nature. It gives rise to the inverse square
law of gravity—the pull of gravity decreases proportionally to the
square of the distance between two objects. Lights seem to drop off in
brightness as the inverse square as well, which means that distant stars
and galaxies naturally appear quite a bit dimmer than those nearby.
On the other hand, the farther away we look, the more galaxies we can
conceivably encounter in our field of view. Add the two effects
together, and the farther you look in any given direction, the more
galaxies you see, even though each more distant one is individually
dimmer. The cumulative brightness will appear greater and greater the
farther you look. Taken to the logical extreme—the infinite recesses of
space—in every direction you look you should eventually see a star, and
the entire sky should appear as bright as the surface of the sun.
Q: So why
is the sky dark at night?
A: If you suppose that astronomers are just playing math games, go to the
middle of a forest. Nearby trees will look big. More distant trees will
look small, but there are so many of them that if you’re far enough
into the woods, you won’t be able to see out in any direction. Now
suppose that those trees were on fire and were as bright as the sun.
The symmetry of the universe would bake us in no time at all, but an
asymmetry rescues us." DaveGoldberg
