You can't compare 2^-160 with a number with a unit attached- it's meaningless. 2^-160 meters is smaller than the planck length, but 2^-160 isn't.

If your unit is "the volume of the observable universe" you get a pretty large volume (on a human scale, anyway): https://www.wolframalpha.com/input/?i=%282^-160%29+*+%28the+...

edit: oh, the units came from the grand-parent post to yours, but wouldn't the correct conversion be "2^-160 earth's surface-areas"? That's actually bigger than the planck area- but still stupid small.

Good catch, I just mentally assigned meter unit to 2^-160.
