sqrt(-det[g])? Why should it be necessary to first make the determinant negative? (we can all see the algebraic requirement of course).
Don't you have any suspicions about such a fictitious looking term?
I have pointed this out before: the metric tensor g is invalid. The term g00 = -1 is purely fraudulent, an arrangement calculated to avoid the product ict x ict and make it look like other real dimensions: e.g. ct x ct. This is gloatingly described in Gravitation by MTWheeler, "Farewell to ict". I think we can agree that it is invalid to make major changes in the coefficients of a matrix like g, just to make up for the defects in the vector field. g is Diagonal and is meant strictly for stretching, but at the same time With a negative determinant it is thereby inadvertently converting positive volumes into negative ones, which is clearly impermissible. It is regrettable that this duplicity has not been challenged anywhere, but it should be up for discussion. The time coordinate has to be retained as ict and it can never legally be promoted as an additional dimension that can be matched up with the real XYZ.
