That does not change the fact that gas expelled into a vacuum does 0 work.
OK.
And now all you have to do is show a link from a credible scientist who agrees with you that this means that rockets don't work in space.
Can you just post it when you find it so I can have a look. Thanks.
If you read my posts, I have written that rockets don't work in a vacuum.
All scientists agree with this.
Great. All I've asked for is a link to an article by a credible scientist saying that rockets don't work in a vacuum.
If they all agree with it then that shouldn't be too hard to find.
All I have posted here is the sheer science of the matter.
You have posted a video of a guy who is tapping on a malfunctioning gauge (with no real rocket in sight, by the way) as evidence rockets do work in a vacuum. When asked for a scientific paper concerning proper protocol for the amount of force to be applied to each tap and the number of taps to be administered to a malfunctioning gauge, the answer is...
Nothing in response.
In addition, you posted a video of a guy who had mounted two model rocket engines inside what is purported to be a vacuum chamber and then fires them off.
I write purported to be, because the same guy WILLINGLY ADMITS the chamber isn't... A VACUUM!!!
Just a couple of minutes in, he looks at the inside of it and states in the video, "Hopefully, this water isn't going to cause to much trouble...it will limit the amount of vacuum I can achieve..."
He tries to get the rocket motor to ignite...fails twice...
Finally, places the rocket motor inside a SEALED AND PRESSURIZED CONTAINER to get it to work inside a container (not a vacuum, but pressure lowered to 15 on the gauge)...
Jeez Louise...
No scientist would ever publish a paper admitting they know rockets cannot work in a vacuum.
But, they all know that free expansion is real and proven...
But, they all know that rockets are real and just containers of gas...
And finally, they all know that rockets cannot work in a vacuum.
