‘Spacetime’ is a way of describing how gravity works in 3D space. You can think of it like the fabric of the universe.
Massive objects, like stars and black holes, can even create wobbles and waves in spacetime when they interact. Scientists at OzGrav study these waves at Gravitational Wave Detectors such as LIGO and VIRGO and use their findings to discover more about our universe.
In this activity, you will work in teams to create your own model of spacetime out of stretchy fabric. Use your model to explore gravity in action and predict how objects in space might behave!
You will need:
- Hula Hoop
- Stretchy Fabric
- Bulldog clips or small clamps
- Golf balls, marbles, or other small, weighted objects.
10 Years of Gravitational Wave Science
This is the story of how Australia helped pave the way to that discovery, how we’ve shaped gravitational wave science since, and where we’re heading next.
