  • The universe is expanding - so does that mean there's a center from which everything is

  • stretching?

  • I mean, it LOOKS like the center is here, because this point didn't move when we scaled.

  • But we could just as easily have watched the scaling from this star, or this one, and they

  • each "look" like the center.

  • In fact, ANY time you scale anything up or down, there's no real center to the scaling.

  • I mean, this square was clearly scaled up from its center...

  • I mean, its corner.

  • I mean, that point over there.

  • The point... is, sure there may be points that stay in the same place because of your

  • frame of reference, which is why it appears to us as if the earth is the center of the

  • expansion of the universe, but to someone in the Andromeda Galaxy it would appear that

  • THEY were the center of the expansion.

  • In short, if you're too close-minded to view the universe from different perspectives,

  • it's easy to think you're at the center of the universe.

  • Maybe that's the universe's way of making us all feel special?

  • But really, we're not.
