hello. I'm working on a philosophical summary of general relativity. i have difficulty understanding tensor. i made the following characterization; can any expert minds here tell me if i said it correctly?

if anyone can take a peek to see if what i got so far is correct that'd be sooooooo appreciated too:

p.s. i also did a special relativity, but it's very long.

the Minkowski spacetime metric corresponds to the Kronecker delta (which marks the metric structure of ++++) only because of the use of the imaginary number in the time element, such that the positive d(\|-1(ct))^2 takes up the place of -c^2dt^2. If the negative sign of the time differential were kept, and the metric structure became +++- as it is in its original form, the metric tensor for the Minkowski metric would then be:

[tex]\left ( \begin {array} {cccc} -1 & 0 & 0 & 0 \\0 & 1 & 0 & 0 \\0 & 0 & 1 & 0 \\0 & 0 & 0 & 1 \end{array} \right )[/tex]
