If you understood as you claim you will not have any trouble
explaining (with math) the following :
1. Why can light be aberrated towards the rear of the car in
Einstein's experimen.

Which experiement? We were talking about a light beam that was pointing
vertically in the frame of the train .. and you said it would be pointing
backward in the opposite direction to the way the train is moving from
the
frame of the track .. that is clearly nonsense.

1. Upward light trip as viewed from the track

Train Motion --->

^ Off-Center Strike on Ceiling Mirror

^Light Emittor on the Train Floor

2. Downward light trip as viewed from the track

Train Motion --->

Totally wrong

Here is what you see from the track (where the '^' represents the light and
the "===" the floor and roof of the train

Note the when seen from the track, the light is moving diagonally in the
direction of the train.

Relativistic aberration would actually make what is observed from the track
ACTUALLY more like

ie further inclined in the direction of the train than classical physics
would tell us. This is sometimes called the headlight effect.



I give up, you are not "fixable".
