Hidden Physics Challenges Feasibility of Interstellar Lightsails

New research reveals complex physical complications that threaten to derail ambitious plans for interstellar lightsail propulsion systems. These findings suggest that reaching another star via this method may be significantly more difficult than previously modeled, challenging the timeline for human expansion into the solar system. The study forces scientists to reconsider the viability of chemical propulsion alternatives and the fundamental engineering hurdles of deep space travel.
