Summary
The article profiles physicist Astrid Eichhorn and her work on asymptotic safety, a theoretical framework that suggests the laws of physics don't break down at the smallest scales but instead reach a fixed point where quantum gravity becomes predictable. Eichhorn's research explores how space-time might be fundamentally fractal at quantum scales, challenging conventional string theory approaches. The article explains how asymptotic safety provides an alternative to string theory for unifying quantum mechanics and general relativity, potentially offering testable predictions about the nature of reality at the Planck scale.

· 4 pulledAstrid Eichhorn spends her days thinking about how the laws of physics change at the tiniest scales.
Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called asymptotic safety, thinks we just need to push a little further.
Imagine zooming in closer and closer to the device on which you're reading this article. Its apparently smooth screen quickly dissolves into a jiggling lattice of molecules...
You dive into a nucleus, and atoms disappear as you enter the domain of quarks.
