Here the v= c asymptote vertical represents the fluidic spacetime membrane (which has a negligible but non-zero thickness).īy examining this graph, a number of things will become immediately and intuitively clear. With regard to the superluminal, substituting relativistic mass for proper mass allows superluminal mass and energy to become definable, non-imaginary properties. By combining several of the equations of special relativity, the underlying relativistic symmetry between subluminal, luminal, and superluminal particles becomes clear. However, nothing in special relativity prevents a massless particle from always traveling the speed of light (i.e., a photon), nor from always traveling faster than light (i.e., a tachyon). Not only would that require an infinite amount of energy, doing so would break causality, and as later, practical demonstrations have shown, the universe does not break causality on a non-quantum scale. Per Einstein’s formulations for special relativity (coupled with Lorentz trans- formations), no particle with real mass can accelerate to the speed of light. Prior to that, thinking was constrained by the limitations of general relativity. Markov’s brilliance was in recognizing the fluidic nature of spacetime and demonstrating the existence of the different luminal realms, as outlined in the earlier, purely theoretical work of Froning, Meholic, and Gauthier around the turn of the twenty-first century. Empirical confirmation followed soon afterward, and the first working prototype of an FTL drive was constructed in 2114. Even the most powerful fusion drives lack the delta-v to jet between the stars as we do now.Īlthough long theorized, superluminal travel did not become a practical reality until Ilya Markov codified the unified field theory (UFT) in 2107. Without it, expansion beyond the Solar System would be impossible, barring centuries-long trips on generational ships or automated seed ships that would grow colonists in situ upon arrival. Let this serve as a primer and quick reference guide for later, more serious studies.įTL travel is the defining technology of our modern era. necessary to outline a brief overview of the fundamentals.
