plus
the atmosphere isn't a constant pressure
it gradually decreases in pressure with altitude
which proves that it is possible to go into space
Via rocket
so there's no huge pressure difference between the edge of our atmosphere and the beginning of a near-vacuum that is space
Oh yeah well my unicorn knows how to use a time machine
?
Rockets don't thrust in vacuums unless you can create a medium to push off
They thrust off themselves
And then it wouldn't be a vacuum
it's not a perfect vacuum
You simply cannot demonstrate it
rockets work
by seperating matter from the craft
this creates kinetic energy
Even if you COULD demonstrate it, your medium doesn't exist
that applies thrust to the craft
no medium is required
think about it like this
let's say
you are in space, floating, right
no gravity, for all practical purposes a vacuum
now imagine
If you think that small tube is a vacuum you are not being honest with yourself
in front of you, is a large block
if you push off the block
you and the rock will both move in opposite directions
the same is happening with a rocket engine
the fuel mixes with oxidizer and is ignited to expand in a chemical reactipno
reaction*
It cannot maintain its differential
therefore you are pushing off pressure
this moves the fuel out of the rocket chamber, essentially "pushing" against the rocket
^^
the rocket moves because of the force applied to it
not because it applies force to a medium
Good explanation
