Put a quarter down a couple of feet away. That's the distance to the next big spiral, the Great Galaxy in Andromeda. On that scale, more sprinklings of coins, little bits of lint, etc., would exend for miles in every direction. The universe is an extremely large place. This seems like such an astonishing and fundamental fact about our reality that I always wonder why it arouses so little curiosity.
City lights block out the night sky, so people forget they're living in space.
Not one person in a hundred thinks about it, ever. Humans were slow to uncover the enormous dimensions of Time, too, over which the universe and earth formed, life evolved, etc. It seems to me that the place to start is just by knowing the facts. There's a kind of serenity in that alone. A problem in writing about enormities is that they get numbing after a certain point.
