Scale
"Planck length is about E-35 m; a human is about E0 m, a ratio of 35 orders of magnitude. The size of the observable universe is E27 m, or 27 orders of magnitude difference. That means the difference between a human and the Planck size is 100 millions times larger than the difference a person and the entire universe!" William Stoertz
Was thinking about this today, and the scope of how much space is "inside" us, versus how much space is "outside" us. I did not realize the scale of difference between the two. Obligatory link to Kurzgesagt's video on this.
