Normal Matter Holds Up: Hadronic Physics Explains Neutron Stars
![The study establishes a relationship between pressure and density in symmetric nuclear matter, constrained by heavy-ion collision data-specifically [latex]Au+Au[/latex]-and informed by chiral nuclear force calculations at [latex]N^{2}LO[/latex] and [latex]N^{3}LO[/latex] orders, alongside constraints derived from kaon production.](https://arxiv.org/html/2603.01933v1/2603.01933v1/figure/Prho.png)
New research demonstrates that standard nuclear physics, using a robust theoretical framework and Bayesian analysis, can fully account for both terrestrial nuclear experiments and observations of neutron stars.
