Sometimes it feels like you are the center of the universe, and in some sense you are, and so is everyone else. Which actually means there is no center. Not everyone can be the center of the universe. So your feeling of being and holding the center is an illusion. And maybe an ego stroke too.
The center can't hold, because it is a fiction, a figment of your imagination. Still, you are important. At least to you. And you play a part in the universe, but it's not exactly of universal, earth-shaking importance, except to you. It's kind of hard to tell what and who is really all that important with so much matter and anti-matter, and people and things. Maybe importance isn't so important.
So below, so above. The cosmologists know that there is no center in the universe, there is just a great expanding. And we are in it, of it, expanding too...
