I would appreciate some numbers

Big thrust now, the cloud clearly touching the rocket

yeah

Because the chamber ceases to be a vacuum

the rocket now has a cloud of gas to push off

Notice it's not movign

not significantly at least

no

it is moving

in a vacuum

dosent matter that its not significant

@halla555 Well it's what they are shown to do in a vacuum in an observable testable repeatable experiment

I.e. not move much

When the chamber ceases to be a vacuum, oh yes then you get lots of thrust

So we can say the thrust is directly proportional to the density of the medium

@halla555 Please explain why the rocket isn't producing meaninful thrust in a vacuum

@halla555 Please explain why the car didn't move forwards when a vacuum cleaner was used to suck out the air?

@halla555 how long does it take for momentum to be transferred?

Is there like a lag or a delay or something?

in a vacuum, what are they reaction off?

how do you get momentum off a medium with effectively zero mass?

```The medium has nothing to do with momentum```

REALLY?

@halla555 So what happened did the rocket just decide to increase thrust 10 fold coincidentally the moment the gas cloud touched the rocket?

Because I put it to you the thrust is not generated by the jet of hot gas, rather the reaction off the walls of the CONTAINER

Tell me what CONTAINER is there in the infinite vacuum of space to generate thrust off?

Not a lot of thrust, so why isn't this hot jet of rocket isn't making the spring+rocket motor moving forwards significantly at all?

Where's the momentum in the opposite direction please?

@halla555 Stop dodging, are you telling me there's a coincidence that the rocket increases thrust ten fold the second the cloud hits the engine yes?

it's irrelevent that rockets are seen not producing significant thrust in a vacuum but yet when pressure comes into proximity of a rocket suddenly for no reason at all the thrust massively increases?

Show me please meaningful thrust in a vacuum of pressures of 10^-4 torr or lower

in a vacuum test chamber

Oh and you know you you live on a spinning water ball how,
