The anatomy of size

The actual size of the Universe is unknown, we haven’t seen its “edges” — the parts that are observable make up a vast territory, but it’s known size is less than a googol in kilometers.

A googol is a very, very large number. The cool thing about the galaxy, North America, and 25 cent coin comparison or analogy below is that you can probably conceptualize it in your head. Not even a computer can process a quarter of all the data a healthy googol of units represents, whatever that may be!
