- Gravitational waves can be derived from the non-linear Einstein field equations and since they are by definition waves they must obey the wave equation:
$u_{tt}=\frac{1}{c^{2}}u_{xx}$ but in General Relativity time and space are not fixed so how are $t$ and $x$ defined for a gravitational wave?

How are gravitational waves derived?
Gravitational waves can be derived from the non-linear Einstein field equations and since they are by definition waves they must obey the wave equation:
$u_{tt}=\frac{1}{c^{2}}u_{xx}$ but in General Relativity time and space are not fixed so how are $t$ and $x$ defined for a gravitational wave?
