@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?

@ligasser@social.epfl.ch Oh my b. I meant only two up arrows. So would that be a hectoknuthmeter (10↑↑3 m)?
