Okay so when there is time-translation symmetry because the metric components do not have any time- dependence, ##\partial_x^0## is a Killing vector.
I'm just confused what this means explicitly, since a derivative doesn't make sense without acting on anything really?
But by 'spotting the pattern' for example I know that for Minkowski space it is ##(1,0,0,0)## and for Schwarzschild space-time it is## ((1-\frac{2GM}{r}),0,0,0) ##, i.e the component multiplying ##dt^{2}## when the metric takes diagonal form anyway,
How is this explicitly?
Many thanks
