Do rockets work in space?

I nasa asked you to take a trip to space in their rocket, would you go?

Op, would you grant that if you fired a rail gun in space, the craft on which the rails are situated would be displaced in the opposite direction to the direction of the projectile.
Further, would you acknowledge that the faster and heavier the projectile, the more force translated into motion of the craft. Does this help you understand propulsion systems in space?

You can also think about this from a statistical thermodynamics standpoint. Consider the following thought experiment: You have two containers, one with high pressure gas and another with lower pressure gas. The high pressure container contains a lot of particles per unit volume (that is, it's relatively "full"), and the lower pressure gas contains few particles per unit volume (it's relatively "empty"). When the two containers are put side to side and gas is allowed to flow, the "full," high pressure container will lose particles to the "empty," low pressure one, causing particles to move from high to low pressure again. Note that this effect is purely due to random movement of the particles. The equilibrium position, of equal particle densities everywhere, is simply the one that has the largest chance of happening (and an overwhelmingly large chance at that) in the long run.

Imagine a line in the middle of a field (both side have equal volume), with 10 people on the left side, and 1000 people on the right side. Every minute, every person rolls a dice and if it lands on one, moves to the other side of the field.

So let's see how the distribution changes, purely driven by randomness:

Seconds; # on left side, # on right side

0 10 1000

1 175 835

2 285 725

3 358 652

4 407 603

5 440 570

6 548 652

∞ 505 505

Of course if you conduct this experiment, there will be some noise because of the small number of participants; with trillions and trillions of particles it will be a perfect equilibrium.
Pressure always goes to equilibrium.

P1V1=P2V2

So in space, the left field has no people (vacuum). Since space is a large volume of nothing, the left side of the field is infinitely larger than the right side of the field. People move to the left side from the right side after rolling 1 on the dice. In order for people to move back to the right side of the field, statistically the person has to win the powerball lottery twice instead of just rolling 1 on the dice.

This is why there is no push back onto the right side of the field.

pv=nrt (pressure times volume=n (number of moles) times r (a constant) times t ( temp).

As molecules (people) move from the right side to the left side of the field, only the n (number of moles) changes and assuming the volume of the fields and temperature stay the same, pressure has to change

and

W=-extpdv (Work= negative external pressure time the change in volume.)

If you want to calculate the work done when people (molecules) move from the right field into the left field, external pressure is pressure of left field, change in volume is the volume of people moving from the right field into the left field.

You didn't even start to answer my question.
There are molecules of gas. What force makes molecules to go from "full" container to "empty" one?

The analogy in this example was people are gas molecules. If you don't understand that is fine with me. Maybe that is why you are not an engineer like your parents. Don't be disappointed, you have a great job as a Russian patriot.

Won't happen, as there is nothing to "thrust" off of, as space is a vacuum according to science...

People are (relatively) intelligent individuals that base their decisions (including in which queue or room to be) on some objective and subjective factors by analyzing them in their brains.
Molecules of gas are chunks of mass with no intelligence: for them to change location there must be some force making them to do it.
It's your fault your analogy is as far as being physically correct as it's possible.

I did not say that gas molecules were intelligent. I clearly said it was statistical movement based on molecule movement. Either you didn't read my post or you are just trolling. If you deny the fact gas moves from high pressure to low pressure then you have lost all credibility. This is almost common knowledge.

I didn't ask you about statistics. I've asked about forces affecting each individual molecule and its behavior. You are just saying that molecules go there because they should do so - not explaining why. And exactly in the fact that you don't understand this why, you are also having problems with comprehend rocket mechanics.

Rockets don't work in a vacuum. NASA-national association of scam artists

Yes molecules have kinetic energy and they bounce of each other and the random movement are statistical like I explained to you earlier. Just like molecules bounce around in the balloon. But you don't see the balloon moving do you. So it is you that doesn't know how a rocket works.

While balloon - or any other container is hermetically closed, all the random bouncing on the inside compensate each other. According to the same statistic you've been talking about.

And now - another thought experiment.
Let's say, you have two containers with air: one have air pressure of 1.5 atm, another - 0.5 atm. Containers are of the same volume. Between them there are a pipe with a closed valve. Also in the pipe a small feather is laying - not blocking anything. Will the feather move the moment valve is opened? What will move it?

Clearly the feather will move because it's the same concept as wind. However the feather is in the path of the flow of air. The rocket is not in the path of air flow.

We'll come to this. I'm trying to explain step by step.

Ok. Next thought experiment.
This time we have container with 0.5 atm air, pipe, valve and feather with no second container - but all this construction is situated in seemingly infinite vacuum (not in space - we still need gravitation - just in a very big volume devoid of air).
After valve is opened, will feather move? If yes, will be the path made by the feather be the same?

Well if the pipe has no air originally, technically it can be considered a second container as the 0.5 atm has flow to the empty pipe when the valve is open. However, if the pipe was already the same pressure as the container, there would be no movement of the feather when the valve is open.

Go to next step.

I'm doing it this way for a reason. Step-by-step makes it clear where we don't understand each other. And, it seem to me, we already stumbled on it.

For the next step we - to be sure - repeat both experiments, but with two feathers in each. One feather is in the pipe "before" the valve, and another one "after" the valve. I.e. in second experiment one of the feathers will be in vacuum and another one is in air.
What happens with each feather in each case?

Both feathers move in each case due the air flow.

Ok. So far we are on the same road.

Next. The same system as the second experiment, but it's vacuum in it. In the container instead of gas there is a gunpowder mixed with solid-state oxidizer. We detonate it (assuming that container is durable enough) and have a lot of CO2 and whatever other gases filling the container up to the same 0.5 atm - and then open the valves.
Feathers?

Both feathers still move because the container is no longer a vacuum because it is now at 0.5atm. The system becomes the exact same as the previous step. Both feathers move due the air flow.

Ok. Next.
The same experiment, but the valve is opened from the start.

There is no movement but if there is combustion then bot feathers move again just like before

Ok. Now we are in the vacuum chamber. on the floor of it is a circle of feathers. In the center of circle the same explosion device are before.
Will feathers move when the explosion occurs?

yes because the combustion gases will fill the chamber so there is air movement. If the valve is open and the other container is also under vac, the feathers will land in the pipe or the second container as this is the area the air will fill last.

Good thing reality is not defined by your lack of comprehension.

If rockets don't work in a vacuum, then how did the satellites which are provably up there, get there? What about STEREO?

No, you didn't understand me. In this case I'm talking about the "big" vacuum chamber - that is on outside of the containers.
