because there is no medium

a prollor on a ship pushes the water

exactly

yep

well, rockets use a different way to propel themselves

not significantly different enough to push itself in a vacuum

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)

a vacuum is one of the lightest things out there, so a helium balloon wouldn't float

and both are gas in nature

a drone wont fly because there is no medium

vacuum is basically nothing

yep

a rocket, generating its own thrust, would fly in the vacuum

don't think so

thrust needs something to push off of

here, tell me how rockets work

what they do to generate thrust

they are propelling gas out the back end to push it forward

thats all you need to say

in an atmosphere they have something to push off of

and something to push into

which slows down the rocket

in a vacuum they have nothing to push off of

rocket won't move

and nothing to push into

you have a guy with a master's degree in technical physics

telling you it won't move

lol

did you watch the videos I linked?

i saw your example already

i did for a bit

one guy with a MSc > 100% of rocket physicists

just showed a disturbing portrait of a man

this guy has a master's degree in technical physics

let me see

he's telling you it has nothign to push off of, it won't work

and hes wrong

because he apparently doesnt understand rockets

well, the link is up above

lets read newtons third law by quote shall we?

For every action, there is an equal and opposite reaction.

maybe we should watch this video and see if he address it

goopy

srry

so if I flap my arms in a vacuum, am I going anywhere?

nope

no medium to propel you up

if I take an oxygen tank in a vacuum and start releasing gas, am I going to move anywhere?

if you let the gas out at a very fast speed and a very high pressure, you're going to fall backwards from the force of the gas ejecting out the tank

if you let it drizzle out nope

nope, won't matter

have you tried it yourself or are you just saying so

you might get thrust but I don't think so, not significant amount

depending on how fast the oxygen comes out ya you might not get much, but you still get it

on the plus side any thrust would be better in a vacuum though

yes it would

because you don't need alot of thrust to move, unlike atmosphere

no air resistance

indeed

you still have the problem of pushing the amount of mass foward
