My explanations prove without doubt that I know what I'm talking about and you are merely duped into thinking that you know what really happens.
Your so-called "explanations" actually prove that you have not the faintest idea of what you're talking about
sceptimatic. And you also seem impervious to the fact that everybody else here—including even the flat earthers—are laughing at you behind your back.
A rocket engine can be regarded as "throwing" a mass opposite to its trajectory—in the form of a high-pressure gas (similar to firing a bullet from a gun). The engine "throws" this mass of gas out in one direction in order to get a reaction in the opposite direction. The mass comes from the weight of the fuel that the rocket engine burns.
The burning process accelerates this mass of fuel so that it comes out of the rocket nozzle at high speed. The fact that the fuel turns from a solid or liquid into a gas when it burns
does not change its mass. If you burn a kilogram of rocket fuel, a kilogram of exhaust comes out the nozzle—in the form of a high-temperature, high-velocity gas. The form changes, but the mass does not, and the burning process accelerates the mass.
And you really need to do some serious homework yourself if you don't even know the basics of how a rocket engine works. You still seem to be confused, in that you think rockets can't work in a vacuum. The atmosphere/air has
nothing at all to do with rocket theory.
