Milky Way Resides on a Giant Dark Matter Sheet, Redrawing Local Cosmology
TL;DR
New simulations suggest the Milky Way sits within a flat, sheet-like dark matter structure spanning tens of millions of light-years, damping inbound galaxy motions and solving long-standing mass and velocity discrepancies that spherical models could not explain. The sheet aligns with the Supergalactic Plane and implies a higher Local Group mass (~3.3 ± 0.6 trillion solar masses) within a broader anisotropic dark matter geometry that shapes the nearby cosmos and possibly early-universe structure.
