@ligasser@social.epfl.ch Could start a Knuth-padded scale of SI prefixes:
kilometer = 10↑3 m
kiloknuthmeter = 10↑↑↑3 m
megaknuthmeter = 10↑↑↑↑↑↑3 m
gigaknuthmeter = 10↑↑↑↑↑↑↑↑↑3 m
etc...
One kiloknuthmeter would be about 333,333,333 quettas stacked in front of a -meter.

@paul@m.pcgt.link OK, you nerd-sniped me. After spending a long time on https://en.wikipedia.org/wiki/Knuth%27s_up-arrow_notation#Computing_10_%E2%86%91n_b and my mind exploding, I asked Claude to give me the number of digits, and its prediction was: > The digit count is not just astronomically large — it can't be written down in any normal sense. So I suppose that even a kiloknuthmeter is larger than our universe. Or did you mean "stacked" in the sense of H_3?
