Starfish are not a good example. They have no holes. Their mouth is their anus.
Comment on Just answer the question you fuckin' nerd
kryptonianCodeMonkey@lemmy.world 5 months agoThat’s not entirely true. We don’t have just one hole going through us. Our holes branch. We have 3 intakes (2 nostrils, 1 mouth) and 2 outputs (1 anus, 1 urethra)

You misread what I was describing.

So starfish are closer to a doughnut than humans.
Knock_Knock_Lemmy_In@lemmy.world 5 months ago
Yes, they are one hole away from a donut. If you include things like nostrils, ears and tear ducts then the internet says we have 7 holes.

Considérons that our lungs and intestines are porous on a molecular scale… And also our sweat pores… Plus are blood vessels (connected to previously mentioned holes)…
Humans have a changing topology depending on the size scale at which you’re working.

I mean that is true of basically all structures and materials. It’s just the coastline problem. How long is the coastline? Depends on the level of precision you apply and the exact time you measure. Theoretically it is infinite if you keep getting more and more granular with it. That’s not helpful or meaningful for general purposes though.
