We are not at the center of the Solar System. We are also not at the center of the Milky Way Galaxy. Since our galaxy does not appear special among the billions of galaxies in the visible universe, what reason would we have to believe we are at the center of the Universe? It is therefore a compelling assumption that we are not at the center of the universe.

How then do we explain the observed fact that distance galaxies are all racing away from us, no matter what direction in the sky we look? This would make sense if we were at the center of a giant explosion. But it is harder to explain if we are not at the center of a giant explosion.

Cosmologists have suggested that space is expanding. They invoke Dark Energy, a violation of the 1st Law of Thermodynamics, imagining that space itself is inflating like a balloon, everywhere, and galaxies are merely being carried along for the ride. Maybe they are right... but it doesn't fail to leave the impression that space itself is composed of some sort of increasingly magical substance, not only able to deform/curve to accommodate General Relativity, but also able to accelerate billions of galaxies away from each other at speeds exceeding the speed of light, without any apparent source of energy!

Maybe there is a simpler explanation... Exhibit A: A timelapse of a star shedding a somewhat spherical shell of gas & dust. It is analogous to the expanding balloon metaphor already used by cosmologists to explain Inflation of the cosmos. Now imagine our visible universe is a small section of that expanding cloud... Would we not see all the other galaxies accelerating away?

We have no idea how big the universe is. Does this not conform to observable phenomena? Prove me wrong.
