To be fair, mathematics are not really concerned with the real, physical world. What’s interesting is that we can built axiomatic rules allowing us to properly define infinite sets and these constructions display surprising properties. It’s all purely abstract but it’s a fun thought exercise if you enjoy that kind of things. Plus it has practical applications sometimes which is good I guess.
