universe is much smaller than a pen.

What if you started outside the observable universe and zoomed all the way down to a human... and then continued to the smallest meaningful scale in physics, the Planck length?
Surprisingly, the zoom required from a human to the Planck length is about 200 million times greater than the zoom from the observable universe to a human!
This mind-bending comparison reveals how incredibly deep the microscopic world is and why the Planck scale is one of the most fascinating concepts in modern physics.
