A new study suggests dark matter may not exist. Physicist Naman Kumar proposes gravity weakens differently across vast distances, following a 1/r rule. This modified gravity model reproduces galaxy rotation curves using only visible matter, challenging long-held assumptions about unseen mass in the universe, and reshaping theories of cosmic structure formation.

NASA’s GNEISS mission will launch from Alaska in early 2026 to probe the electric currents that drive auroras. Two rockets will fly through glowing auroral arcs, releasing sub-payloads whose radio signals act like a CT scan. By mapping electron density and direction, scientists aim to improve space weather forecasting and better protect satellites and communication ...
