Current space probe speeds are fundamentally limited by propulsion technology
Current space probe speeds are fundamentally limited by conventional propulsion technologies, prompting ongoing research into advanced methods such as directed-energy, laser-sails, and field propulsion.
The claim is specific and testable regarding aerospace engineering and physics. Multiple retrieved papers explicitly discuss how conventional chemical and electrical propulsion technologies impose fundamental speed limits on spacecraft, and outline alternative propulsion concepts required to overcome these barriers.
