OK not really but I've read the "rocket scientists" have been lying about how rockets work; I've learned that rocket engines don't actually work in a vacuum.

Of course you ask "but why would they lie, I don't understand". They lie because they're hiding the fact the Earth is flat and there is no space to travel to or in. We're inside a giant underwater terrarium and atmospheric life is an artificially created novelty.

Need proof? Differently shaped rocket nozzles produce varying degrees of thrust depending on atmospheric pressure.

To answer your question, I need to deeply research on rockets or else I should meet a scientist.

No, you don't need to do any deep research. You just need to do the experiment I proposed earlier in the thread (which has not yet been refuted):

There seems to be an issue with rockets exploding or falling into the ocean.

Rockets sometimes do that, turns out it's not as easy as you might think to shoot a rocket into orbit. It would be far more suspicious if rockets bound for orbit had a 100% success rate.

Back to your original assertion, which was that rockets don't work in a vacuum. You're wrong.
You don't even need a vacuum chamber to test this, here's a simple experiment that you can do at home to prove conservation of momentum.

Put yourself in a state of low friction, for example sit in a chair with wheels or stand on a skateboard. Now, pick up a heavy object, and throw it away from you. You will move in the opposite way to the object. This is primary school level physics.

In this analogy, you are the rocket and the object you threw is the rocket fuel. Now, you might think that this only works because the object is pushing off the air or some such bullshit. Well then, why not try it with a much lighter object of the same volume, such as a balloon. You will see that if you throw an gas filled balloon in the same way, you will barely move at all.

Congratulations, you just proved a fundamental law of physics, and subsequently that rockets certainly can work in a vacuum!
