Moon Hoax - Rockets CANNOT work in space

one of the biggest hoaxes of all time!

rocket propulsion cannot work in space.

you get tricked by being told about newtons third law and how the propellant pushes against the body so therefore (equal opposite) has to push the rocket.

but newtons third law ironically proves this to be false if viewed from the other way round, the propellant cannot push against a vacuum (zero force) so in turn (equal and opposite) applies zero force to the rocket/vehicle itself.

can anyone find me a video of a rocket, firecracker or something similar creating force in a vacuum?

The propellant is pushing against the weight of the rocket. Duh.

Look up 'mass' in a dictionary.

Someone doesn't understand how thrust works... or motion in general

Physics fail. Stay in school.

So, if you were in a space suit, and you were a few feet from a bottle full of nitroglycerin/oxidizer mixture you'd feel nothing when the bottle exploded.

Because Rocket fuel is oxygenated and fucking volatile.

Yes, but what's the point? You'll just call it fake.

How do rockets work in a vacuum?
Quite well, actually.

Complete physics fail.

Also, a vacuum is not "zero force," or a lack of all force. Gravity, ffs, is a force FOUND IN THE VACUUM OF SPACE.
Criminy, someone get this guy a high-school textbook!
