No, I want to hear your explanation. If you say rockets can't work in space, how was the ISS constructed?

How do I know the ISS isn’t simply a balloon or airplane?

Re: Rockets need an atmosphere to propel
Let me explain how a rocket engine works.

Consider a cylinder( or any shape) combustion cylinder of an appropriate size, without any escape port for expanding gases. Imagine letting kerosene or any other fuel into the cylinder, along with some liquid oxygen to quickly oxidize the fuel. If it ignites (explodes) without an escape, the pressure inside the combustion chambers rises to an equilibrium. For funsies, say 5000 lbs/sq in is generated.
The cylinder won't move in any direction, with 5000/lbs sq in against the walls. IF A MEANS OF ESCAPE IS PROVIDED (the exhaust nozzel) the pressure at that spot(of the nozzle) is immediately reduced as the explosion leaves the chamber. HOWEVER, at the opposite end of the chamber(opposite the escape nozzle , the pressure against the chamber bulkhead is still nominally 5000/lbs sq in. It is the higher pressure against the forward bulkhead that pushes the chamber in one direction. If there is no atmosphere outside of the chamber, the gas can escape even faster allowing the combustion to (maybe) provide MORE pressure against the forward bulkhead. The jet of the engine "pushing against the atmosphere" means nothing. That jet is just waste gas.

If gas is released from the container, the entire container reduces in pressure. From you analogy, the bottom of the pipe is the bulkhead pressure which should push on the scale.

Wrong.

The booster rockets completely null their horizontal velocity while in space and then come back to land at the launch site. Ergo, rockets do not need an atmosphere to propel themselves. Do not accuse this footage of being fake. I filmed it myself.

You're floating in a zero-g vacuum, holding a bowling ball. You push the bowling ball away from you as hard as you can. If you were correct, the bowling ball would move away from you, but your position in space would remain unchanged. You're clearly wrong and dumb.

I knew you were gonna say that.

They always try to use the premise of if I or you havent personally seen it then it must be fake! Its a international conspiracy and nothing thats been observed or validated by thousands of independent researchers, engineers, enthusiasts matters.

Have you or I ever personally seen a nuclear bomb detonated? No but im pretty sure that we can agree that its effects are most certainely real and well documented as complex as thier construction, and physics principles of operation are to understand.

Explain your expirement set up in more detail then you can really quantify its flaws.

Re: Rockets need an atmosphere to propel
You're mistake is in thinking that reaction mass must push against something, like we swim in the water. Actually propellant throws mass in the opposite direction of travel, using conservation of momentum to move ahead. (Please look this up.) The faster and heavier the propellant, the better.

 Quoting: TGus


This was disproven by the pipe experiment. Mass was expelled out of the pipe and therefore according to you there should be an opposite force, but this is not seen.

Perhaps you can think of a simple experiment showing that rockets do work in space.

finally someone with a right explanation of rockets.
but i still think this has nothing to do with newton and his 3rd law. its pressure driven and not action/reaction driven. if it is action/reaction driven, it would not work in a vacuum like OP said
sometimes the truth is easier to find in the reaction rather than the picture
