The determinant of the metric is negative. So, sqrt(-det[g]) is a real number. <shrug>

That is because nothing can travel beyond the speed of light. <shrug>

Yes, of course. <shrug>

[g]_00 (your g00) is not -1. It is +1 --- (1 ? 2 U) thing. <shrug>

If nothing can travel beyond the speed of light, the signature of the metric ought to be (+1, -1, -1, -1). <shrug>

The fault of GR starts way before the construction of spacetime. <shrug>

[g] (your g) does not have to be diagonal. It is made diagonal to simplify the already complex math. If [g] is not diagonal, it would be relatively impossible to solve for the field equations. <shrug>

There is no ict thing if the signature is (+1, -1, -1, -1). <shrug>
