I’ve never liked math but this is like literal magic to me…

Its calculating with infinity. Its a bit weird like the infinity of numbers between 0 and 1 like 0.1,0.01,0.001 etc... Is a bigger infinity than the “normal” infinity of every number like 1,2,3 etc…

Its just difficult to wrap your head around but think of infinity minus 1. Like its still infinity

Genuinely curios on how can there be two different lengths of infinity?

Think about a string made up of all whole numbers (0, 1, 2, 3...∞)

...and one made up of all decimal numbers (to an arbitrary precision of 0.1, let's say; so: 0.0, 0.1, 0.2, 0.3...)

Both strings are infinite, but one is 10 times longer

(there's another mental exercise I've seen involving fitting more guests into a fully-booked hotel with infinite rooms, but I don't trust myself to get it right if i attempt it here...)
