THE OBSERVABLE UNIVERSE The universe is big. Even scientists don't know how big, but current estimates are 400,000,000,000 (400 billion) stars in our galaxy alone. Total number of galaxies? 100 billion just in the currently observable universe, roughly, give or take a few billion. Think about that, next time you are walking the dog and doing the grocery shopping. If that doesn't blow your mind, nothing will. |
