Actually , you got it wrong, Harry.
And it is such a simple problem. "G" is indeed correct, how would the
light go diagonally in the track frame? Moreover, why would the light
ray get inclined forward in the direction of the train motion?

Its very simple .. it HAS to be inclined forward in the track frame in
order
to be vertical in the train frame.

Well, you may be in for a surprise, it is inclined backwards, not
forwards in the track frame. Harry here will be more than happy to
explain that to you (once he understands my explanation to him)

Nonsense.

2. Downward light trip as viewed from the track

Have fun! Hope you learned something new.

No .. I already knew you had no idea what you're talking about.

Its perfectly simple .. if the light is travelling vertically in the train,
then from the frame of the track it is inclined in the direction of the
travel of the train .. it has to be. There is no other possibility- Hide quoted text -

"It has to be" has no room in science.Bye.


Light emitted in my frame of reference is glued to my frame of
reference in terms of velocity
Just because the source of light is on the train and "inside" the
train does it mean it is in a different frame
of reference? What if it was an open train? what if it was a light
source moving along the tracks ( commonly called an UFO)
My frame ( frame of the tracks) behaves as if it was filled with
stationary ether ( relative to me and the tracks)

What if it was a laser pointer travelling over the tracks ? what if it
was horizontal? Would we find the laser travelling a greater
distance because it is moving? Will the ray of light emitted from the
laser travel a greater distance ?

Is it starting to unravel yet, folks?

""If I had a world of my own, everything would be nonsense. Nothing

contrary wise, what is, it wouldn't be. And what it wouldn't be, it
