Last month, Caltech scientists made a historic announcement: For the first time, they directly detected gravitational waves, confirming an important piece of Einstein’s theory of relativity, which he published more than 100 years ago. The discovery was made possible by the twin Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors located in Livingston, Louisiana, and Hanford, Washington, which can detect the minuscule movement created when a gravitational wave passes by them.
In our latest Teachable Moment, JPL education specialist Lyle Tavernier, shows how you can use simple materials, such as gelatin, marbles, a mirror and a laser pointer, to turn this exciting news into a lesson in modeling that meets Next Generation Science Standards.
