A groundbreaking new theory may finally crack the code Einstein spent decades searching for—a unified field theory! Scientists have proposed a geometric model linking electromagnetism and Einstein’s dream, potentially reshaping our understanding of the universe. Science continues to push boundaries, fulfilling century-old dreams.

Fresh from the @j824h_arXiv_astro_ph : calculating (numerically) the impact of a wave hitting a spherical overdensity in the cosmos, the wave suffers from a Shapiro delay and thus shows interference patterns. So do we really need fuzzy dark matter to observe interference?! arxiv.org/abs/2504.08286

arXiv.orgNumerical evolution of Maxwell's equations for wavefronts propagating through a spherical gravitational potentialWe present a scheme for numerically solving Maxwell's equations in a weakly perturbed spacetime without introducing the usual geometric optics approximation. Using this scheme, we study light propagation through a spherical perturbation of a stationary metric in the linear limit. Going beyond geometric approximation allows us to explore the wave optics effects that occur when the wavefront propagates through the gravitational potential. We find that the wavefront breaks on the gravitational potential due to the Shapiro time delay, i.e. due to the slowing down of light when propagating in an inhomogeneous spacetime. This again leads to constructive interference, resulting in a persistent frequency dependent amplification of parts of the wave amplitude. When the wave length is shorter than a certain threshold set by the induced gravitational mass, the waves are reflected on the curvature gradient.
