Planck the scientist? The Planck length is 10 to the −20 times the diameter of a proton. Why are we using something so small to talk about galactic distances?
It turns out, as beings living in the 10^0m scale, we are much closer to the size of the universe 10^27, than to the smallest possible distance, 10^-35.
Which boggles my mind, I did not imagine the Planck length to be this small, if it even makes sense to use the word "imagine".
It has nothing to do with smallest possible length or something like that and it's just a common mistake in non-scientific physics articles that has sadly spread.
