You are the center and the circumference. The center of you would presumably be some atom behind your navel. Somewhere in the center of that atom is a whole mess of subatomic particles and so on and so forth. It works the other way as well because you are also the circumference. You don’t end at your skin, you extend infinitely outward with your sphere of influence. Across great distances and between the smallest of spaces, you exist. You are both of the earth and on it. Same subatomic particles at the center of you are also at the center of the earth. Just as you extend beyond your skin, the earth extends beyond the crust. It includes the wind and the sky. Beyond the edge of the sky, earth’s gravity influences spheres across the universe. You are both the center of the universe and the reason the universe exists. This is a heavy burden.
