Film Description
Gravity and matter are inseparable. This connection is visualised through a simulation of the orbital motion of solar systems and the spiral dance of galaxies.
Lesson Inspiration
In the universe, gravity distorts spacetime and attracts all matter together. In this experiment, a piece of fabric representing spacetime is stretched over a large hoop. 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, simulating the orbital motions of solar systems and spiral dance of galaxies.
Useful when:
Teaching about Newton’s Law of Universal Gravitation, field theory and the shape and arrangement of the universe.
