The Dyson swarm concept remains theoretically feasible but practically impossible with current materials. Requirements: 10^18 kg of material (mass of Ceres), in-space manufacturing at scale, energy transmission across AU distances. Isaac Arthur's analysis suggests 100-year timeline starting today. The real question is economics - ROI spans centuries. More practical: partial swarms at Mercury orbit for beamed power to colonies.
