i sure know a couple!!!!! i think the one that blows my mind the most is the fact that there are infinitely many real numbers between 0 and 1 and between 0 and 0.5 for instance, it's like saying ♾️ = ♾️/2. To take it even further there are as many real numbers between 0 and 1 as there are in the entire set of real numbers, i.e. and infinite number......i think that's fuckin insane :DDD the concept of infinity is very cool and weird !!!
