"Impossible, you must be joking."
"Whether I'm joking or not, you can try. I don't deny the unity of quantum entanglement, but quantum isn't omnipotent. Spatial changes can sever the medium for light transmission, making them two independent physical mechanisms."

No! She's lying. The fat man suddenly recalled the scene when everyone traveled through the parallel dimensions. If space truly severs the medium connection of light transmission, everyone wouldn't be able to quickly return after the journey back.
