> We take the sun being the center of the universe for granted today, but it was an extremely non-obvious fact for the smartest people in the world for millenia When did the sun become the center of the universe? I thought it wasn't even near the center of our galaxy, much less the universe, though I seem to recall that expansion makes it look that way because all the other galaxies we can see are moving away from us. |
