That may be but you're objectively wrong.My opinion is worth a lot to me. What it's worth to you is not my issue.
There can never ever be a constant.Momentum conservation is not limited to atmosphere, it's a constant in physics.
What do you mean by free floating?The escaping rocket gas has momentum. The rocket is part of the same momentum system, is freefloating and is therefore affected by the thrust of the engine.
@Nukehasslefan does not like thisIf a spacecraft is travelling at a rapid speed between 2 objects in space, and a smaller vehicle exits the spacecraft without being connected, how does the small vehicle stay at the same speed as its ‘parent’ spacecraft?
I’m reading 2001: A Space Odyssey and a pod has exited Discovery while it travels between Jupiter and Saturn.
The pod would have to travel as fast as Discovery? But according to the book it only has enough acceleration to “hover on the moon”.
As in not a static wall.There can never ever be a constant.
What do you mean by free floating?
It keeps us on the ground, yes.So atmospheric resistance is the force that stops us all floating off into space? Well I never
I mean if you want to simplify it right down, the rocket is pushing against its own exhaust.It keeps us on the ground, yes.
We are simply under pressure but it doesn't stop us from floating off into space because I don't believe in the space we're told. It just keeps us on the ground by our very own dense mass that displaces that atmospheric set of layers we are stood in.
No need for any wall as long as there's a resistance to action which atmosphere caters well to as does water.As in not a static wall.
You've got it in your head that propulsion needs resistance. That's not how it works.No need for any wall as long as there's a resistance to action which atmosphere caters well to as does water.
Exhaust as in what?I mean if you want to simplify it right down, the rocket is pushing against its own exhaust.
It's exactly how it works.You've got it in your head that propulsion needs resistance. That's not how it works.
Each to their own.Where did you learn this unknown knowledge @Nukehasslefan? It must be a super secret organisation, as it contradicts everything I've ever read or learnt
Wrong.The rocket does not operate based on exhaust gases, it operates on expelled burning gases against the atmosphere, not burned gases.
It's not man. Propulsion is part of Newton's Law. It works like that on Earth maybe because it's used to OVERCOME resistances.Exhaust as in what?
Are we talking about the thrusting burn or the burned-off gases?
You see there are two systems in operation. One follows the other.
The burn creates the thrust...the work and the burned fuel from that work is the exhaust.
The rocket does not operate based on exhaust gases, it operates on expelled burning gases against the atmosphere, not burned gases.

If there is no air friction to slow a vehicle then there's equally no air friction to aid propulsion, meaning nothing moves in what we're told is a vacuum.
Ayyyyyyyye.Here we go. Flat earther science denier to the rescue.
If there's o leverage to create resistance to action then you cannot get a reaction and it means you cannot be propelled in the opposite direction to what you eject.It's not man. Propulsion is part of Newton's Law. It works like that on Earth maybe because it's used to OVERCOME resistances.
In a vacuum without any resitances then even if you chuck something out of the back of a car in space, the car will move forward at the same rate as what you chucked out the back.
You're still imagining this from an earthbound perspective.If there's o leverage to create resistance to action then you cannot get a reaction and it means you cannot be propelled in the opposite direction to what you eject.
Imagine this.
If you can somehow float in a space vacuum then there is no up-down or side-to-side for you.
So what keeps you still and how do you push yourself away from where you are?
Let's assume you are inside a cardboard box that is equally taped shut in all directions.
You need to push one end open to release your hands or feet.
Can you tell me what would happen?

Well first of all you will have had to be moving to get into that position, then use some force acting in the opposite direction to your motion (if we're talking spacecraft, then gas propulsion will be it) to slow you and then stop you- otherwise you would just keep going forever until you hit something. Once you are in equilibrium, you have no forces acting upon you, and have stopped completely, you do not need to do anything to stay there- you will stay there forever unless something comes along and hits you. To carry on moving, you need to provide a force to overcome your net zero of acting forces, which would be more rocket propulsionIf there's o leverage to create resistance to action then you cannot get a reaction and it means you cannot be propelled in the opposite direction to what you eject.

I don't believe that, do people really think this??You're wasting your time, marra. Check out the "Send a flat earthier into space" (sic) thread. In amongst his MANY statements of utter bullshittery, he claimed that "not all right-angles are equal".
He believes we live on a lemon squeezer-shaped world with a projector in the middle projecting the sun and stars onto the dome above it, gravity doesn't exist, the moon is a reflection of the sun... it goes on and on.
