Fractal Space-Time: A Scale-Symmetric Path to Predictive Quantum Gravity
Physicist Astrid Eichhorn explains that gravity may be made predictive at all scales via asymptotic safety—a scale-symmetric, fractal-like space-time that reaches a fixed point around the Planck scale, linking microscopic physics to particle properties, constraining some dark-matter candidates, and potentially coexisting with other quantum-gravity approaches—while remaining testable through experiments.
