Dr. Richardson theorizes that some unknown force lowered the temperatures of the objects so as to lower the Earth's gravitational pull, thus making the objects easier to lift, regardless of their size and weight. Katsumiya determines that such an action could only be accomplished by a force beyond the Earth.
Dr. Richardson suggests that an unknown force altered the temperature of objects to reduce Earth’s gravitational pull, making them more manageable to lift irrespective of their dimensions and mass. Katsumiya infers that such an operation would require a force surpassing Earth's own capabilities.
