Rockets do not work in the vacuum of space. You will believe anything "expert" scientists say.

so lets say you wanted to move 5kg of air from one room to another. Can you simply push it into the other room like you can with a 5kg boulder? Solids are not fluids. Fluids act according to fluid dynamics.

Phage the punting stick was the example given , not the paddle .

Roadgravel your video contains an open admission that rockets do not work in space , that they need at least some atmosphere to be effectual at all .


It did not. You must not be able to understand words. Now you have started lying.

I pointed out that there is no difference when it comes to the physics involved. The stick, or the paddle, will push water backwards to differing degrees.

Yes, yes you can.

really? are you sure? Can you show me how you did it? If you used a leaf blower, then you are using pressure gradient force (propeller creates an area of low pressure). So again how did you push the air like you did with the boulder?

And you know full well what the degrees of difference mean .

It is not about pushing against something.

Turbine, actually.
But for the umpteenth time, pressure gradient force causes the air to move, yes. It is the momentum of the moving air which causes the kid to move. Newton's third law.

Notice that the blower intakes are on the sides?



Btw, what's the shape of the world?

Yes, a paddle will move more water backward than the stick will. And the forward force depends upon how much water is moved backward and how fast it does so. How much force, not whether or not force.

Newton's third law.

Uhm... maybe you should listen more carefully. They're talking about control surfaces, like ailerons and flaps. That's why he mentions the shuttle having to get deeper into the atmosphere for them to work.

so it's not the same as pushing a boulder then? Do you move boulders using leaf blowers? Can you use a leaf blower to move a boulder in space?

Same effect. Newton's third law.


Can you use a leaf blower to move a boulder in space?
No. But you can use a rocket.

now instead of having propeller on the intake. Suppose you put vacuum on the end of the leaf blower. Air comes in thru the intake and out the blower. But no opposite force? why?

You said :

You know you're over the target when you start taking flak . That's Bill Nye The Lies Guy is it not . Anyhow his nasa bud just told you and I , and anyone else with ears, that gas thrusters need atmosphere to work otherwise they'd be pushing against nothing . They only used those thrusters on the shuttle to steer it on the way down , because they don;t work without some atmospheric pressure to push against . And that's the topic of the thread and what he just confirmed , on video , provided by you .

Same goes for Phage we've been here before , you both (and nasa themselves and onthat video) are providing confirmatory evidence on topic but in a consistently veiled format . Newtons 3rd law - cheers for that .

Suppose you describe how you are going to do that?

So your leaf blower example in null then. Since you can't use it to push a boulder in space.

low pressure caused by vacuum will cause air from the leafblower to move into the vacuum.

You asked how to move 5kg of air from one room to another. A leaf blower would do the job nicely.

Read my question again and then try to answer it.

It wasn't Bill Nye that said it. He mentioned the thrusters, and then the other person in the video said that control surfaces don't work in space because there's nothing for them to push against. Control surfaces work by changing airflow over them. No air, no working control surfaces. I've listened to it twice, with another person listening, and he clearly says "control surfaces don't work".
