Gravitational waves are disturbances in the curvature of spacetime. They are generated by accelerated masses that propagate as waves, moving at the speed of light, outward from their source.
The Kinect sensor will detect visitors standing anywhere in the grid and create a gravity well at that location. When visitors move around the space, the gravity well follows with them and affects nearby objects.
This exhibit is one of the most popular as it is accessible to all ages and demographics.
