correct.

That's not 0 + 0 = 0. I don't know why you're making ridiculous statements like the momentum of the spacecraft is zero. It's clearly moving so it's non-zero.


simply because in the earlier attempts to explain that reactionless propulsion is possible you and others on this forum were always saying that the pipe would either never move at all , or that it would just wobble back and forth and never really go anywhere , thats why.

if you want me to understand the way your thinking then you should answer the questions below yourself.

What do I mean by "system"

What does "total" mean in "total momentum"

What is the meaning of a negative momentum?

If object A has momentum pA and object B has momentum pB, what is the total momentum of the system comprising A and B?
a) pA + pB
b) pA - pB
b) |pA| + |pB|
c) 0
d) Requires more information to answer


then I will know.

but I do know that total momentum means all 3 stages in a 3 stage event.

not just a few hand picked stages to suit you.

like in the first 3 stages in the first event.

+1 pipe due to the -1 mass acceleration
-1 pipe due to the mass reverse in direction in the 1st turn
+1 pipe due to the mass reverse in direction in the 2nd turn

simple addition shows that the pipe would have momentum.

(+1) + (-1) + (+1) = +1 pipe momentum.

you have never agreed that the total momentum of the first three stage event would result in the pipe having momentum just like the spacecraft after it runs out of fuel.









3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
