This comparative index measures how close real-world science and engineering are to the technologies imagined in Star Trek. We track technologies from the Star Trek universe against real-world scientific progress using NASA's Technology Readiness Level (TRL) scale, mapping each innovation from its fictional introduction to its current scientific status. By quantifying humanity's progress toward Star Trek's optimistic future, we demonstrate how science fiction can inspire and guide real-world innovation.
This resource is free and open-access, ensuring it reaches scientists, engineers, educators, students, and anyone curious about the intersection of science fiction and reality. The Subspace Index goes beyond simple comparison by applying rigorous scientific frameworks—NASA's TRL scale, prominence scoring based on episode appearances, and scientific basis classification—to each technology. This systematic approach demonstrates that understanding our technological trajectory requires more than speculation; it demands structured analysis that connects fictional visions to real-world research, helping distinguish between near-term achievable technologies and those requiring fundamental physics breakthroughs.
