alright

2018-10-16 05:58:41 UTC  

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

2018-10-16 05:58:51 UTC  

but rockets use a different method to generate thrust

2018-10-16 05:59:34 UTC  

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

2018-10-16 06:00:13 UTC  

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

2018-10-16 06:00:30 UTC  

which in turn ejects the material extremely fast outward

2018-10-16 06:02:07 UTC  

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

2018-10-16 06:03:24 UTC  

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

2018-10-16 06:04:14 UTC  

any problems you've thought of?

2018-10-16 06:04:30 UTC  

yes, rockets need something to push off of

2018-10-16 06:04:35 UTC  

its a propellant

2018-10-16 06:04:36 UTC  

i explained that yes

2018-10-16 06:05:09 UTC  

it propels something forward by pushing off something

2018-10-16 06:05:17 UTC  

yep

2018-10-16 06:05:24 UTC  

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

2018-10-16 06:05:35 UTC  

it pushes off of the fuel coming out of the nozzle

2018-10-16 06:05:52 UTC  

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

2018-10-16 06:06:07 UTC  

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

2018-10-16 06:06:33 UTC  

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

2018-10-16 06:06:33 UTC  

look at latest video

2018-10-16 06:07:09 UTC  

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

2018-10-16 06:07:22 UTC  

both throwing stuff out the back end to push it forward

2018-10-16 06:07:54 UTC  

(propellant)

2018-10-16 06:08:03 UTC  

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

2018-10-16 06:08:04 UTC  

and both are gas in nature

2018-10-16 06:08:16 UTC  

a drone wont fly because there is no medium

2018-10-16 06:08:18 UTC  

vacuum is basically nothing

2018-10-16 06:08:21 UTC  

yep

2018-10-16 06:08:36 UTC  

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

2018-10-16 06:08:54 UTC  

don't think so

2018-10-16 06:09:07 UTC  

thrust needs something to push off of

2018-10-16 06:09:09 UTC  

here, tell me how rockets work

2018-10-16 06:09:19 UTC  

what they do to generate thrust

2018-10-16 06:09:42 UTC  

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

2018-10-16 06:09:50 UTC  

thats all you need to say

2018-10-16 06:09:51 UTC  

in an atmosphere they have something to push off of

2018-10-16 06:09:59 UTC  

and something to push into

2018-10-16 06:10:06 UTC  

which slows down the rocket

2018-10-16 06:10:15 UTC  

in a vacuum they have nothing to push off of
