He and other NASA engineers have been designing and redesigning these instruments, with the goal of using them to slightly warp the trajectory of a photon, changing the distance it travels in a certain area, and then observing the change with a device called an interferometer. So sensitive is their measuring equipment that it was picking up myriad earthly vibrations, including people walking nearby. So they recently moved into this lab, which floats atop a system of underground pneumatic piers, freeing it from seismic disturbances.
The team is trying to determine whether faster-than-light travel — warp drive — might someday be possible. …
“Space has been expanding since the Big Bang 13.7 billion years ago,” said Dr. White, 43, who runs the research project. “And we know that when you look at some of the cosmology models, there were early periods of the universe where there was explosive inflation, where two points would’ve went receding away from each other at very rapid speeds.”
“Nature can do it,” he said. “So the question is, can we do it?”
