# What are gravitational waves made out of?

Relevance

Gravitational waves are just oscillations in the curvature of spacetime. As a gravity wave passes you, it squeezes you from the sides and stretches you from head to foot. Then the opposite, it squeezes you head to foot and stretches you sideways. It alternates many times per second. This is the frequency of the wave.

Gravity waves are made by any accelerating mass. But they are much too weak to feel or measure.

It is when Gravity is stretched to breaking point

like an elastic band going Boinggggg !!

Before a so called gravitational wave be described it is necessary to Understand gravity and its causes as well as the cause of motion.

Basically a wave is a disturbance in a medium which causes a moving force.

It's the stretching and pulling of space-time.

Go ahead - make some: just by waving your arms, you're creating gravity waves... those are much too weak to be detected, but the idea is the same as when two black holes circle each other faster and faster until they finally merge; the movement of mass through space-time creates a disturbance that is propagated - until we finally detect it here on Earth.

This is the classic question -- what is actually waving when we are talking about "fields", rather than the kinetic motion of atoms and molecules involved when dealing with sound or water waves .

And here it's the more abstract, and mathematical, concept of (energy) field potentials disturbing the coordinates of spacetime

Gravitational waves are made out of gravity. Remember that gravity is defined as a metric tensor field, the components of which define how time and space behave in the presence of gravitating sources. A gravitational wave is simply a propagating change in that metric field that can carry energy/momentum at the speed of light.

So, if you are facing a gravitational wave, you will be alternately stretched and compressed as the wave passes. The stretching and compressing is just a change in the metric field as it passes.

What's a sound wave made of? Energetic compressions of gasses, right? Gravitational waves are energetic compressions of spacetime.
