Is there *any actual example* of infinity in physics? I’m reading about Ramanujan’s summation method to assign a value to a divergent series (eg, 1 + 2 + 3 + 4 + … = -1/12), and it seems to me that *every time* infinity shows up in equations, it’s nature’s way of telling physicists that their model is wrong

No there is not. Actually there’s a school of mathematians who don’t believe in things like infinity and real numbers: en.wikipedia.org/wiki/Finitism

Yeah I was going to say, this isn't exactly "physics". It's that the associative property doesn't work with infinities. Most physicists work with infinite series that are convergent anyways so the space tends to work with series that focus on a finite set of terms, like Taylor series expansions.
