Spacetime from Quantum Fluctuations
![The evolving abundance of dark matter halos exceeding [latex]10^8\,M_{\odot}[/latex] demonstrates a redshift-dependent density, calculated via the Sheth-Tormen mass function and a standard transfer function, and subject to modulation by a power boost parameter-a relationship sensitive to underlying cosmological parameters and the scale-dependent behavior of that boost.](https://arxiv.org/html/2603.14533v1/fig_hmf_boost.png)

Collision Course: How Molecular Impacts Drive Magnetism in Radical Fluids
![Molecular dynamics within fluids are governed by stochastic exchange interactions-[latex]J_{ij}[/latex]-arising from discrete, pairwise collisions, where each encounter generates a random variable fluctuating in both magnitude and sign with a zero mean, fundamentally reflecting the unpredictable nature of molecular encounters.](https://arxiv.org/html/2603.14677v1/Fig1.png)
New research reveals that magnetic properties in concentrated radical solutions aren’t determined by static interactions, but by the constant jostling of molecules.
