This isn't real life. It's the Internet and I'm a rude admin. Deal.

The thrust or force applied by a propeller to a ship or air plane is what drives the ship or air plane, while the water or air tries to stop the action by friction force. The thrust of a jet engine is just a force applied to the vehicle of the jet engine.sceppy wrote:
The thrust is the key, obviously, because that's what pushes the dense water at the atmosphere, so fast, that the atmosphere tries to counteract it faster...creating what you see as a spread out fast jet of water, as opposed to a dense pour if you were to have a bottle full of water as it will simply just fall through the air with little resistance and no air inside the rocket for the atmosphere to bother to try and equalize with, so no propulsion.
So here is more video of thrusters firing in a vacuum, just for the Rockettes.closet astronaut
Besides all this, there's PLENTY of video footage of thrusters working in space, according to this theory, they shouldn't work either, and how could we get the Hubble into orbit.

The above holds true as long as we are in the atmosphere.Heiwa wrote: The thrust or force of a rocket engine fitted to a rocket in vacuum space is provided by the displacement of the mass of hot exhaust gases at high velocity through a nozzle of the rocket engine - as per Newton.

Here's where you rocketry guys lose me. Any Rocketry Forum specialist feel free to pipe in here:As we are in space, there is no friction and little gravity applied to the rocket, and the rocket engine thrust/force will change the velocity of the rocket.
Now this we agree on. Every object with mass moving around in space is doing so because it was pushed on by some unknown initial force (Big Bang, Hand of God, Breath of the Dragon, etc...). These objects only change speed or path because of gravitational field interaction or collision with another solid object.When you switch off the rocket engine (no exhaust or pollution), the rocket will continue at constant speed only subject to gravity forces of distant planets or the Sun.
And I thought you didn't believe in NASA. Why did your views change? To say you are against NASA and believe in space rockets does not compute. You are either confused or misrepresenting one or some of your beliefs.Anyone believing that a rocket engine does not work in space is simply wrong.

It's the Wizard of Oz effect. Just trust in NASA and do not look behind the curtain. Do not investigate their claims with respect to the laws of physics and chemistry. Investigation of NASA science is heresy. That's why the people on those forums are running after us with burning torches and pitchforks.Flabbergasted wrote:I think it is safe to assume that the ideas seeded by this debate on NASA/Disney rocket propulsion and vacuum physics are germinating fast in the minds of those rank-and-file Rocketry Forum members who follow the debate in silence, the non-watch dogs and non-larryds who are sincere enough to digest a new input before thoughtlessly joining in the jeering and sneering.
Or am I being naïve?
The thing about ideas is that once they are out of the box, they won´t go back to sleep! Happy assimilation!

No, replacing the outside atmosphere with vacuum doesn't change anything. The displacement of the mass of hot exhaust gases at high velocity through a nozzle of the rocket engine - as per Newton (into the vacuum) - will displace the rocket in the opposite direction (in the vacuum).Boethius wrote:The above holds true as long as we are in the atmosphere.Heiwa wrote: The thrust or force of a rocket engine fitted to a rocket in vacuum space is provided by the displacement of the mass of hot exhaust gases at high velocity through a nozzle of the rocket engine - as per Newton.

What is so secret about NASA apart from the fact that they hide that rockets don't work in space?It is not possible to fly to the Moon and back (inspite of Wikipedia/NASA shills suggesting otherwise) because you need plenty of fuel/energy to do it using the best rocket engines available by the military very secret industry, but you cannot carry all the fuel with you, because you get too heavy.
