## In brief

- A ScienceAlert article reports that physicists have found a mathematical limit to making time run backward.
- The article's headline frames the work as identifying a constraint on reversing the direction of time.
- The source text provided is only a headline and teaser, so the study's details are not available here.

## Why it matters

The result concerns why time appears to flow in one direction, a foundational question in physics that bears on how theorists model time-reversal scenarios.
