@FrogTheCat Please show me a rocket in a vacuum chamber of pressures of 10^-4 torr or below producing meaningful thrust whilst the vacuum chamber pressure remains below 10^-4 torr.
@FrogTheCat Care to explain this please?
Vacuum my ass
i see some pixels
and somethng vibrating
Notice the bit of string flapping up and down
vibrating due to rocket firing? yes
Classic dodge
oh i see, the part you gifed is after the rocket fires , when it blows back
probably some cool down cycle
*"I see pixels"* is going to be my response to anyone sending me images from the ISS or the like.
Clearly, it works, here.
he gifed a part that was after the rocket firing
Where?
*I see pixels*
it's really pixelated isnt' it
the original video is high res
here's a paper about that test : https://pdfs.semanticscholar.org/8747/a34532c0b95567218de8abf1dcc2a2e19519.pdf
Here's a discussion about the facility : https://www1.grc.nasa.gov/facilities/isp/
2. CHANGING THE DENSITY OF THE MEDIUM: https://imgur.com/i0Cww6Y
so why do objects of different densities fall at exactly the same rate
and objects of the same density can fall at different rates depending on orientation?
1 vs 6
the sulfur hexaflouride would go down in air, it is more dense, the more dense gasses are lower than the less dense ones
not if there was some springyness on parts of the feather
feather isn't a rigid body
Bibleman do you believe in the Bible
drop a slinky, it doesn't all fall at the same time
