The Hyperbolic Time Chamber has an entrance at its center, located in a central building with two side wings with housing, food supplies, bathing quarters and sleeping quarters. There is no night or day in the Room, but the surroundings remain a constant bright iridescent white aurora. Its reflective floor is of undefined area, and the Room's boundaries are thought to stretch to infinity in all directions even though it appears to have a definite atmosphere, limiting its size. Goku explains to Gohan during their visit to the chamber that the air grows increasingly dense in the recesses beyond the plaza, which can be threatening as the Hyperbolic Time Chamber has no definite boundaries. The Hyperbolic Time Chamber represents a separate dimension from that of Earth.
