TL;DR
This paper suggests that formal infinities in quantum field theories are meaningful indicators of new physics and should be explored further, challenging traditional views on divergences.
Contribution
It introduces a new perspective that interprets formal infinities as meaningful signals of new physics, emphasizing their importance in quantum field theories.
Findings
Formal infinities are markers of new physics.
Even simple quantum field theories contain more infinities than previously recognized.
Exploring these infinities can lead to new physical insights.
Abstract
High energy physics features many ingenious tools for extracting finite results from formally divergent expressions. This brief note argues from a new perspective that all such formal infinities are meaningful markers of new physics. As such, they deserve to be explored in detail -- and even the simplest quantum field theories have more of them than is commonly thought.
