The same way compressing into the below stack by helicopter blades
So it can't.
Good job showing you don't understand how helicopters work either, and completely avoiding the issue yet again.
It was a rather simple question.
You have a book sitting on a pile of air. You then claim that compressing the air makes the book go higher.
But now you are appealing to a completely different situation where you are putting more air in, which would make the air compressed, which then allows the air to decompress and push the book upwards.
But that is still decompression pushing the book up, and it is still the gas pushing the book up.
Move the air out the way and push it behind you and use that as your leverage...and so on.
So the rocket, moving the air inside it and pushing it behind it to use as leverage means it can move, including through a vacuum.
So rockets do work in a vacuum.
It's a compressed gas expanding into a compressed gas to compress it further and that gas decompressing to resist that and push back.
Why doesn't the initial decompression push the rocket up?
But again, in your nonsense, how does the push get transferred to the rocket?
According to you, the gas leaves the rocket and is completely unable to push up on the rocket.
Then this gas which has already left the rocket, interacts with the air below, and somehow magically this pushes the rocket up.
It's like you jumping from a height onto a trampoline.
No, it is nothing like it.
As you jump on a trampoline, the trampoline stretches and applies a force upwards to you. This initially slows you down and then makes you move upwards.
The force on you comes from the trampoline in contact with you.
But in order for this to match your nonsense, you need to claim that that can't push you up, and instead by magic, something not in contact with you at all pushes you up.
Appealing to other situations easily explained by actual physics, but inexplicable by your nonsense doesn't help you.
Stop telling people to think and start thinking yourself.
If the sponges compress it means something is compressing them into a larger resistance due to pushing into them
Like a book sitting on top compressing it as it falls?
So the book goes down from the air compressing.
Perhaps I should have addressed the other side first.
How does it decompressing, where the gas gets bigger, make the book go down?
As above, with your nonsense, you appeal to the decompression pushing the book up.
So what you are really saying, is some crap happens before hand, then after that, the air decompresses, pushing the book up as it expands.
And as a bonus question, just what evidence at all do you have that gas works the way you claim rather than the way mainstream science has shown it does?
Simple experiments that show how a stack works and why expansion/contraction/vibrations work to create what we see happening.
And this is just more pathetic deflection.
Notice how you didn't provide any actual evidence and instead just appealed to it existing?
There is no evidence
You ignoring the evidence doesn't just magically make it go away.
You dismissing it as fake or CGI, just because it shows you are wrong doesn't magically make it go away.
There is plenty.
This includes all the documentation on rockets working in space.
It includes the very satellites in orbit around Earth, put there by rockets working in space which take pictures of Earth and send them back, or provide services such as satellite TV and GPS, which can't be faked by land based systems unless you pretty much cover the entire Earth in transmitters and even then you still have massive issues.
It includes all the experiments which shows Newton's laws of motion in operation.
This includes the thought experiments which show the insanity of rejecting Newton's laws of motion, where forces are magically generated from nothing, where for example, if you have some object and you push it from behind, cutting the object in half will magically double the acceleration while keeping the force applied constant, which makes no sense at all.
It includes all the examples provided to you in this thread, showing that gas must push outwards in all directions all the time. Things you have been completely incapable of rationally responding to to provide an alternative explanation other than by trying to completely redefine words and pretending that because a rate is negative the value must be as well.
And it includes the very simple questions you continue to avoid which among other things shows a very simple fact, either rockets do work in a vacuum, or gas can magically be held inside a tube exposed to a vacuum, without leaking out.
If you want to honestly say there is no evidence, then you need to deal with all that. You need to be able to explain how the gauge reads a value, rather than rapidly returning to 0, without any force being applied to it, noting that the gas "resisting" is still applying a force.
You also need to be able to answer the very simple questions asked of you, which you have ignored countless times, or just provided pathetic non-answers.
Again:
What is the gas pushing against to allow it to move (which isn't the rocket and which the rocket can't push against)?
How does the gas magically know to stop pushing outwards in all directions and instead only push towards the opening?
How does the gas move towards the opening if it is pushing towards it, meaning it would be pushed away?
If you wish to claim you have evidence for your fantasy, you need to actually provide the evidence.
Provide some situation which your fantasy can explain (without contradicting itself) which real physics can't.
If you push on someone against a spring and they move back as you keep pushing you can be said to be applying positive continuous building of pressure.
And there you go conflating rate and value yet again.
STOP TALKING ABOUT THE RATE!
START TALKING ABOUT THE VALUE!
Do you understand the difference?
Pressure is a VALUE!! Not a rate.
Yes, you can be said to apply a continuous building of pressure, but that is not what we are asking.
Instead we are asking about the ACTUAL PRESSURE!!! Do you understand that?
If you lessen the amount you are pushing, YOU ARE STILL PUSHING!!!
Do you understand that?
You even admitted that yourself.
Reducing the amount you are pushing doesn't mean you are no longer pushing.
Likewise, the pressure of the gas reducing doesn't mean it is no longer pushing.
If you resist the motion applying a force to slow it down, YOU ARE STILL PUSHING!!!
Do you understand that?
If you don't push, then the person or object moves as if you were not there.
Do you understand that?
What point are you trying to make?
It is quite clear, in order for the pressure gauge to not have its spring expand fully and return to the 0 point (and thus read 0), it needs to have a force acting upon it.
i.e. the gas is still acting on the gauge, unless the gauge reads 0.
This is the same with the gauge.
And because the gauge needle drops so does the pressure on it
This all nails it.
You are right that this nails it, but not in the way you think.
As the needle drops, the pressure drops. Notice that it doesn't magically become negative and stop pushing.
It is still pushing, it just drops.
So the gas, even while exiting the container still applies a force to the gauge.
The same happens with the rocket, with the gas inside pushing on the rocket, making it move.
i.e. rockets do work in a vacuum.
Again, if you wish to claim otherwise, and claims rocket can't work in a vacuum you need to deal with these very simple questions:
What is the gas pushing against to allow it to move (which isn't the rocket and which the rocket can't push against)?
How does the gas magically know to stop pushing outwards in all directions and instead only push towards the opening?
How does the gas move towards the opening if it is pushing towards it, meaning it would be pushed away?
For the first one, unless you can provide some magical entity there are only 2 options, either rockets work in a vacuum, or gas can remained trapped in a tube which is open to vacuum.
