Can someone explain loop capacitance and loop inductance IN AS MUCH DETAIL AS POSSIBLE.

Also what are the squiggly traces on most digital, microcontroller and computer pubs

Do you really expect an answer to that? Take a moment, step back, look at what you wrote, and ask yourself this: Does anyone else in the world know shat that means?

The squiggly lines, as you call them, are likely delay lines in very high speed circuits.

Way too small of an image.

Those serpentines are there because the speed of light is not infinite.

For improved noise immunity, very high frequency signals often are routed as a differential pair of traces instead of a single trace. It is critically important that the two traces be of equal length. Otherwise, the transitions of the two differential signals will arrive at the receiver chip pins at different times. This timing error is called skew, and it is very real.

Can a few millimeters of trace difference really matter? Yes. At these speeds, the numbers of vias in the two trace path must be equal, hard 90 degree corners are forbidden, etc.
