you can also make educated guesses like that from elements found and things like the magnetic field

@Human Sheeple where does that exist on the globe model

@Human Sheeple it isnt a complete vacuum that is almost impossible but its the gravity holding the gases to earth

@tripolarbear what's gravity?

@Human Sheeple that is not the vacum crushing that its the atmosphere

there wasn't 1 atmosphere on teh outside of the lunar module

@tripolarbear atmo-WHAT?

if you dont have something in the barrel pushing out from inside it will get crushed from the pressure from outwards

so why doesn't the ball earth explode then?

what do you mean

what pressure is trying to spread it apart

diffusion

Pressure is force divided by area, so there is more pressure (meaning more force) being applied to the outer surface of the tin can, but there is no pressure/force inside it cause its a vacuum

Hence its crushed

@noah please look up the definition of pressure for me

what CAUSES pressure?

gravity

@Human Sheeple Force

well in the case of the atmosphere

thats a video that has been disproven

rockets work fine in a vacuum

Real vide @tripolarbear

Pressure is force divided by area. That isnt exclusive to atmospheric pressure that's just a general definition of pressure.

yeah real video

Rocket's clearly not showing thrust in a vacuum

same guy disproved it

Care to give me your definition then?

https://www.nasa.gov/multimedia/imagegallery/image_feature_1281.html

The really real rocket in the really real vacuum really did not produce meaningful thrust really.

@Human Sheeple that's not true

depends on the type of rocket

it's tested all the time here's an example

i dont get what you are aluding to
