NASA's official stance on faster-than-light (FTL) travel is that it is currently considered purely speculative and not supported by any scientific evidence or theories. According to our current understanding of physics, particularly Einstein's theory of relativity, the speed of light in a vacuum is considered an absolute speed limit.
NASA's research and exploration efforts primarily focus on the development of space missions and technologies that align with our current scientific understanding. This includes robotic exploration, crewed missions to nearby celestial bodies, and the study of our own solar system and beyond. While NASA remains open to new ideas and innovative concepts, the current consensus in the scientific community is that FTL travel is highly unlikely based on our current understanding of physics.
It's worth noting that scientific knowledge is always evolving, and breakthroughs in the future could potentially challenge our current understanding. However, as of now, NASA's stance is grounded in the principles of known physics and does not support the feasibility of faster-than-light travel.
