What this work contributes
Lubin develops a directed-energy route to accelerating small probes using an external laser and a sail, transferring the heavy power system away from the spacecraft. It supplies a useful systems comparison for onboard-power limits, beam infrastructure, and the distinction between a projected architecture and demonstrated hardware.
Where the evidence stops
The relativistic-flight roadmap is a proposal, not a demonstrated interstellar flight system; beam power, aperture, pointing, sail survivability, and communications remain system constraints.
