Topical Science – Gravitational Waves

Physicists have confirmed the existence of gravitational waves, ripples in the fabric of spacetime that travel at the speed of light. Einstein’s Theory of General Relativity predicted the existence of these waves 100 years ago, but this is the first time that they have been detected directly.

They used highly sensitive equipment to measure two black holes, which collided many light years away. The detection proves gravity travels as a wave, but what is gravity?

For younger learners watch the Tigtag film Gravity in our Universe with your class to discover more.

For older learners, watch Black Holes to learn more about the mysterious phenomena that allowed scientists to collect this data.
