Just get on with it,, or don't. Either way is fine by me.
Imagine that there is a piston in space that function like I told you earlier. Now, if we extend this piston, both the piston base and the piston rod will move apart from each other, right?
I don't know what you mean by piston base.
Fully describe what you're saying so it becomes clear.
I posted a fucking picture. Look at it.

Ok, so the electric motors push the piston and the housing apart from each other.
Ok fair enough, now what?
Now, imagine that on this housing we had an automated piece of machinery that, after the piston has extended, could weld an extra piece to the piston so it could extend further. This would also push the housing further, although as it is more massive it won't be pushed as much. Doesn't sound impossible, right? Then, imagine that we also had a piece of machinery that could melt down material from a reserve and mold it into new pieces, that could be welded onto the piston. So we can extend the piston really far now, but the housing is pretty heavy when it is fully loaded so it won't get pushed far. But, as it get's emptied and the piston gets more massive, it will start being pushed more, right?
I honestly have no clue what you're getting at. I've already explained what would happen so welding bits on to whatever isn't going to change anything.
I am not done yet, so please stop evading. Do you agree with what I have written so far, and can you imagine it?
No I can't. It makes no real sense.
It's like me telling to imagine that I've pushed some spaghetti through a tube and then added another strand to the back of it, then another, etc. It makes no rational sense to do what you're saying.
You need to go for another analogy.
Yup, it's exactly like the spaghetti thing you brought up. Obviously you could imagine that spaghetti thing, so you definitely can imagine it. We have a machinery like the one I am describing. Now, does it work as I have told you? If not, explain why.
Regardless of what you've said, you are not moving anywhere except against each object.
You still do not have any leverage but you can't seem to see that.
Think about it really carefully and clearly.
Down on the ground, in atmosphere, every push has leverage and your body has useful mass to use in moving an object due to that mass having leverage with either, the ground by use of feet or by atmospheric pressure upon that body's mass, also creating a leverage.
Now think carefully about what I'm about to explain.
If you were to run at a sumo wrestler, you would be using the ground and your feet, plus body muscles aided by atmosphere to charge at that wrestler.
Once you hit that wrestler, you will maybe slightly move him but you will probably be absorbed by his bulk/mass and then catapulted back because his feet and mass that is clamped to the ground by atmospheric pressure upon his mass, is his leverage against your mass thrown at him.
If you were standing in front of each other and used your arms to push each other away, then you would be the one that was pushed away.
Now take that into your vacuum of space, or near vacuum as we are told.
In that space, assuming you could live happily floating, or how the silly scientists depict it, you have body mass each but it means nothing.
You are no different than the sumo in what you can do against him or he can do against you. Only the look is different.
So take a run at the sumo now and what happens?
The sensible thought is: you can run. You can't move , except to move your arms and feet; flapping them about with no movement in any direction gained.
Same goes for sumo man.
So what about if you were both face to face with bent elbows, palm to palm with each other.
Ok, you can now push off each other, right?
Wrong.
Remember, nobody's mass has any gain because there are no leverage points in your space for either person to create a resistant force against the other.
All you both have, are bent arms ready to push against each other, but as I've explained, your mass and his are meaningless in the nothingness of your space.
So you push against him and he pushes against you. What you see are both of your arms outstretching and that's your lot.
You end up fingertip to fingertip with no more movement because the only leverage you both has was counteracting both your bodies.
Now you can sit and argue that mass is relevant in your space and give out all kinds of magical reasons, but you common sense should really kick in and realise how silly it all is and how silly space actually is.
You should come to the conclusion that rockets to space are not feasible, so something else must be happening. Make your own mind up ... or, you stick to your space rockets and such. It means nothing to me because what I'm typing here is for the benefit of those who can actually think for themselves.
