In other words, space, and the universe, might not be entirely definite—locations of things might not be completely definite and might be transmitted in quantum bits that vary ever so slightly. He likens it to the idea of "pixels" in a photo. From afar, you see one picture, but if you zoom in far enough, you see tiny points that make up the larger whole.
reality has a limited amount of information, like a Netflix movie when Comcast is not giving you enough bandwidth. So things are a little blurry and jittery
So, if the team detects movement, it's possible that the movement is being caused by space not being a completely set thing, in which case, we could be living in the Matrix.
Now operating at full power, the Holometer uses a pair of interferometers placed close to one another. Each one sends a one-kilowatt laser beam (the equivalent of 200,000 laser pointers) at a beam splitter and down two perpendicular 40-meter arms. The light is then reflected back to the beam splitter where the two beams recombine, creating fluctuations in brightness if there is motion. Researchers analyze these fluctuations in the returning light to see if the beam splitter is moving in a certain way—being carried along on a jitter of space itself.
