The walls onboard appear mostly smooth and seamless. chaotic managed to take a possible look behind the scenes: "We were standing in one of the rooms at the far end of the ship. Smaller workers, barely three feet tall, approached and removed a panel from the wall. Behind it, two pipes were revealed. He [my "guide"] explained to me that these pipes would extend in a ring, going along the rim [oft he ship]. He also told me the purpose of the rings. Each ring creates a variable, oscillating field that interferes with the field of the other ring. The variation in oscillation leads to local differences in the interference, allowing the ship to travel through space in a controlled manner. It wasn't electromagnetism. In the same context, I remember a display with complicated formulas in our mathematics and sine curves. Of which I understood nothing at that time. I was no longer afraid at that point. I only felt curiosity."
