No RoS is a bogus concept. It requires that M' moves wrt the light
fronts from the ends of the train and thus violates the isotropy of
the speed of light in the train.

It is meaningless because all you are saying is that if you stand
closer to a light source A than light source B then you will see A's
light before B's light. BTW PD and wormy are idiots.

Hey idiot there is no order of event in this case. There is only one
event....the bug dies at the instant when the tip of the rivet hits it
and both frame must agre to that. The paradox is: the rivet frame
claims that the bug dies before the head of the rivet hits the wall of
the hole and the hole frame claims that the bug dies after the rivet
head hits the wall of the hole. This means that one of these claim is
false....my money is on the hole frame's claim because there is no
phyiscal length contraction.

Hey idiot... my numbers on the SR effect from the ground clock point
of view and from the GPS point of view are correct.

Hey idiot it is not an assertion....they use the SR eqations to
calculate the SR effect and use the gravitational potential effect
equation to calculate the gravitational effect. The combination of
these two effect is the GR effect.

Sure there is contradiction as follows:
1. You agree that the bug dies in both frames at the same instant of
time when the tip of the rivet hits it.
2. You made the assertion that the bug dies beforew the head of the
rivet hit the wall of the hole and then made the contradictory
assertion that the bug dies after the head of the rivet hits the wall
of the hole....these are two different instants of time.
