![The study demonstrates that for a rapidly spinning black hole with [latex] a_{\*} = 0.99 [/latex] and maximal deformation [latex] \ell_{\textrm{NP}} = 0.1137 [/latex], the horizon radius [latex] r_H(\theta) [/latex] deviates from that of a Kerr black hole, and the innermost stable circular orbit (ISCO) radius [latex] r_{\textrm{ISCO}} [/latex] is significantly altered as a function of spin and deformation-with parameter combinations leading to naked singularities excluded from the analysis.](https://arxiv.org/html/2602.16562v1/x2.png)
New research details a method for testing the predictions of Einstein’s theory of gravity using X-ray reflections from material swirling around black holes.

A new analysis reveals the fundamental precision limits for measuring neutrino properties and uncovering the origins of matter-antimatter asymmetry.
![The study reveals that asymmetry following a spin flip evolves predictably over time, with the rate of change-quantified as [latex]\delta\mathcal{S}(\rho\_{A},Z\_{A})=(\Delta S(\rho\_{A},Z\_{A})-\Delta S\_{0})/\log t[/latex]-scaling consistently across varying subsystem sizes, suggesting a universal characteristic of this dynamic process.](https://arxiv.org/html/2602.15969v1/x10.png)

A new framework proposes that consciousness isn’t a unique biological quirk, but an inherent property of systems driven to reduce uncertainty and predict the future.
![The study demonstrates that birefringence induced by hypothetical axion-like particles (ALPs) within protoplanetary disks causes a time-varying rotation χ of the polarization plane of scattered light, measurable through oscillations in local Stokes parameters [latex]Q_{\phi}[/latex] and [latex]U_{\phi}[/latex], and thus providing a potential signature for these elusive particles.](https://arxiv.org/html/2602.15611v1/x1.png)
