Scientists Watch Collision That Created Gravitational Waves

Scientists Watch Collision That Created Gravitational Waves

In August 2017 the whole Earth shook. Gravitational waves from a merger of two neutron stars billions of years ago in the distant Universe finally reached the Earth. This caused the Earth to stretch and squash as the wave passed by. This stretching and squashing was detected by LIGO as a gravitational wave. Almost instantly telescopes all around the world pointed at the possible position of the gravitational wave signal and for the first time managed to detect the event at many different wavelengths of light. This revolutionary discovery has changed our understanding of the Universe in many ways.

In this video I describe what happened in this amazing discovery. If you want to find out more, read the awesome article from ICRAR student David Gozzard here.
