When the first New Voyager Program probe swarm fired all of their collected energy into the face of the second probe swarm, their targets’ solar sails were at maximum extension. They soaked up the energy the forward probes had collected just like they had originally soaked up the energy from the massive laser arrays orbiting Earth. Those arrays accelerated them up to twenty percent of lightspeed, and the overloaded communications lasers of the forward swarm slowed the surviving probes back down to the speed of the Alpha Centauri Trinary star system. It was a simple plan. Expensive, but simple.
