GRAVITY

A simulation of the orbital motion of solar systems and the spiral dance of galaxies.

Series: PHENOMENA, Episode 7: GRAVITY, Runtime: 04:29

Synopsis:

Gravity and matter are inseparable. This connection is visualized through a practical simulation of solar system and galaxy formations. In this experiment, a piece of fabric representing spacetime is stretched over a large ring. A heavy ball is dropped into the fabric, distorting it like a star distorts the space around it. Smaller ball bearings are then propelled into the fabric. They spiral around the centre mass, replicating the orbital motions of solar systems and spiral dance of galaxies.

This experiment was filmed under ultraviolet light to enhance the orbital motions of the ball bearings. The high resolution camera was operated with a BOLT motion control robot, matching the rotating motions created by the galaxy simulation.
