rocks don't move under their own power

you might throw a rock, but that is you causing it to move

well, there is a 1000 page book on the history of liquid fuel rockets

kinetic force applied to the rock

yes, i understand how a rock is thrown

that won't work with a rocket

you can't throw a rocket in space

kevin, how does a rocket move forward on earth

it propels stuff out the back from an ignition that propels it forward

propellant

its pushing off the the ground or atmosphere to create that propellant

so, the force of the propellant leaving the rocket pushes it forward?

its like a swimmer in water

you put a swimmer in air or vacuum, they can't swim

you put a rocket in water or vacuum, it doesn't work

a rocket can work in water

um, not very well

ummm, why do you think subs carry ballistic missiles

well, they are designed to work in water

i mean torpedo's are usually used for a reason

torpedo's usually aren't rockets, they are designed to work in water

Subs carry ICBMs goopy

you dont launch an ICBM underwater, but at the surface

those don't fly under water, ICBM's are fired by a sub going topside and firing them from the surface of the water

Jinx

no, subs dont surface to lanch anymore

https://www.youtube.com/watch?v=1aPvGGvnAGQ , 3 stage rocket

the rocket turns on outside of the water tho

its ejected from the water

the 2nd staage

anyhows, we are missing the point

rockets don't work in vacuum

how do you think it gets above the water goopy

kevvvvv long time no see

yo

are yall talking about missiles?

you have someone with a master's degree in technical physics telling you rockets don't work in a vacuum

then he shows you an example

I show you a fan that doesn't move toilet paper in a vacuum

how do you think propellant is going to propel the rocket anywhere with nothing to push off of?
