There is some irony in the fact that the Hubble Space Telescope has shown that Edwin Hubble's classification scheme for galaxy shapes only works in the later stages of the universe. What have really deep pictures (going way back in time) taken with the Hubble Telescope shown about galaxies long ago (in the first few billion years after the Big Bang) ?
A) long ago, all the galaxies were spiral shaped; there were no other shapes at all
B) long ago, galaxy shapes were not (for the most part) regular and organized; galaxies looks chaotic and lumpy
C) long ago, there were no galaxies at all; stars were evenly distributed through space and had not yet formed galaxies
D) long ago, galaxies were much larger than galaxies are today; those very large galaxies broke apart and made the galaxies we know
E) you can't fool me; the Hubble Space Telescope has a smaller mirror than the largest telescopes on the ground. We can't use it to see galaxies that long ago.
