It's A Big Universe

Today's Astronomy Picture of the Day shows NGC 7331, a nice spiral galaxy in the constellation of Pegasus. "Just" beyond lie a number of galaxies that are probably roughly the same size as NGC 7331 (which is roughly the size of our home galaxy) but are ten times as far away.

Humans are generally incapable of understanding astronomical distances and geological time. Especially Hollywood executives and religious fundamentalists.
