Jan 15, 2021 at 3:54 comment added kaylimekay @G.Smith the metric shouldn’t have units. OP is writing vectors with inconsistent units and then putting c in the metric to “fix” that and make the norm of the gradient have units of inverse time. Yes, it’s unusual...

Jan 14, 2021 at 22:51 comment added G. Smith Why does your Minkowski metric have $c^2$ for the spatial components?
Jan 14, 2021 at 22:49 comment added G. Smith Your $\partial_t$ should be $\partial_t^2$. You can write a wave equation for any metric.

Jan 14, 2021 at 22:07 comment added Charlie What do you mean "the metric of the universe"? There are a lot of places in the universe where the spacetime metric deviates greatly from the Minkowski metric.
