a propeller requires a medium to push in order to create lift

you need to be traveling by some other method, like light sails or something that works in that medium

you know that flies cannot fly in a vacuum

when you eject alot of stuff very quickly through a small area is creates thrust

someone put flies in a vacuum and tested it

it didnt fly

🍿

appearantly they can survive but they cannot fly without enough atmosphere

rockets dont use wings or propellors though

its a 3rd way to generate kinetic energy

rockets have some stabalizors

they aren't flapping wings though which would create lift

...

we can't survive in a vacuum too

mind if i do a quick run through on rockets and you tell me what you find wrong kevin?

go ahead

alright

we know how propellers work, by pushing air or another medium

but rockets use a different method to generate thrust

they do this by ejecting extremely hot pressurized gasses through a small opening

the reason it goes through the small opening is so it has a higher pressure inside the fuel tank

which in turn ejects the material extremely fast outward

now, newtons's 3rd law states any reaction has an equal and opposite reaction, meaning when the gasses are ejected backward, the rocket is ejected forward. once the gas leaves the nozzle its useless and serves no other purpose.

welcome to reality

air only slows rockets down because of air resistance, in a vacuum the gasses would eject faster and there would be no air resistance, only helping the rocket

any problems you've thought of?

yes, rockets need something to push off of

its a propellant

i explained that yes

it propels something forward by pushing off something

yep

there isn't enough surface area to propel the rocket forward with nothing to push off of

it pushes off of the fuel coming out of the nozzle

just like in this latest video the air balloon will not move the car in a vacuum

propellant of the air won't push it forward just like a rocket won't

are you comparing blowing air to push a car to a rocket?

look at latest video

I'm comparing stuff that works in atmosphere that doesn't work in a vacuum

both throwing stuff out the back end to push it forward

(propellant)
