Given infinity that doesn’t make sense.

Ironically it is actually infinite.

The example doesn't claim that infinity is a number

A real life and relatable example to illustrate what infinity (if it exists) really means. The repercussions are huge.

Yea, but what's infinite about it?

Koshkin β€’ Jul 24, 2018 β€’ View on HN

Sure there is an infinity without a sign.

I've always gone with "for really small values of infinite"

∞ is not a number. Using it as a number is a hack invented by mathematicians.

Infinity is not a number, it's the absence of a limit.

Yes, with Natural numbersCurious what is possible in Integer numbers> That's what happens when you try to reason with infinity ;)Ah yes! Fascinating subject
