Stunning video reveals NASA”s world biggest vacuum chamber that replicates space, where according to Laws of Gravity, bowling balls and feathers ‘weigh’ the same.
Brian Cox tested the laws of gravity at NASA Space Power Facility, used to test spacecraft in space-like conditions, near Cleveland, Ohio
Almost all of the air is removed from the chamber to make it a vacuum. The two objects are then dropped and hit the ground at the same time, because there is no air resistance.
