*looks at the combustion chamber and its distinct somethingness*

2018-10-16 05:50:25 UTC  

nothing happens, rocket doesn't move

2018-10-16 05:51:09 UTC  

what causes thrust then

2018-10-16 05:51:17 UTC  

thrust is caused in atmosphere

2018-10-16 05:51:27 UTC  

GOD causes thrust

2018-10-16 05:51:27 UTC  

no thrust = no movement of the rocket

2018-10-16 05:52:07 UTC  

rocket works in atmosphere because it has stuff to push off of and its designed to work in this medium

2018-10-16 05:52:13 UTC  

it doesn't work in a vacuum

2018-10-16 05:52:15 UTC  

let me try to simplify everything, gas coming out of the chamber has to hit a medium to be propelled?

2018-10-16 05:52:51 UTC  

it has to push off of nitrogen gas and stuff it finds in the atmosphere

2018-10-16 05:52:58 UTC  

or the ground

2018-10-16 05:53:10 UTC  

hmm, you know propellers right?

2018-10-16 05:53:16 UTC  

with nothing to push off of, its not going to propel itself forward

2018-10-16 05:53:17 UTC  

how does the force from pushing off the air go to the rocket?

2018-10-16 05:53:18 UTC  

they push air

2018-10-16 05:53:58 UTC  

propellers are moving air around to create lift

2018-10-16 05:54:04 UTC  

yes

2018-10-16 05:54:06 UTC  

or propel a submarine in water

2018-10-16 05:54:10 UTC  

the usually pull the aircraft through the air

2018-10-16 05:54:15 UTC  

because it has a medium to push

2018-10-16 05:54:31 UTC  

they aren't going to work in a vacuum either

2018-10-16 05:54:45 UTC  

because there is no medium

2018-10-16 05:54:47 UTC  

a prollor on a ship pushes the water

2018-10-16 05:54:51 UTC  

exactly

2018-10-16 05:54:52 UTC  

yep

2018-10-16 05:54:54 UTC  

well, rockets use a different way to propel themselves

2018-10-16 05:55:20 UTC  

not significantly different enough to push itself in a vacuum

2018-10-16 05:55:24 UTC  

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

2018-10-16 05:55:37 UTC  

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

2018-10-16 05:55:49 UTC  

you know that flies cannot fly in a vacuum

2018-10-16 05:55:55 UTC  

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

2018-10-16 05:55:58 UTC  

someone put flies in a vacuum and tested it

2018-10-16 05:56:03 UTC  

it didnt fly

2018-10-16 05:56:04 UTC  

🍿

2018-10-16 05:56:24 UTC  

appearantly they can survive but they cannot fly without enough atmosphere

2018-10-16 05:56:31 UTC  

rockets dont use wings or propellors though

2018-10-16 05:56:52 UTC  

its a 3rd way to generate kinetic energy

2018-10-16 05:56:58 UTC  

rockets have some stabalizors

2018-10-16 05:57:17 UTC  

they aren't flapping wings though which would create lift

2018-10-16 05:57:40 UTC  

...

2018-10-16 05:58:00 UTC  

we can't survive in a vacuum too
