But how do you get into the house?

That plate looks like it’s viewed from the bottom (like it’s glued to the ceiling). Trippy.

Just searched a bit, looking into how the length came to be and found this from wikipedia. https://simple.m.wikipedia.org/wiki/Planck_length “The Planck length does not have any precise physical significance, and it is a common misconception that it is the inherent pixel size of the universe.” What I found elsewhere was that it’s the only length one can get out of the universal constans of G, c and h. So as far as I know with my limited know how is that the planck length is useful or more convenient than other lengths in quantum physics.
