Astronomers have uncovered two extraordinary cosmic structures that are challenging long-held assumptions about the nature of ...
The Einstein–Gauss–Bonnet framework extends Einstein’s theory of General Relativity by including a higher-order curvature term that gains dynamical relevance in dimensions beyond four. This approach ...
