How do rockets fly in the vacuum of space!?

I just figured this out.

"How does Superman slow down in space?"

He exhales. Really hard.

And that offers a theory, of how he starts moving forward in space if he has nothing to push off from?
This may be the reason he wears a long cape.
Because it can help direct the "thrust"?
 
Hi kind sires,

Just fund a video on youtube that was quickly deleted a few days ago about how all the space programs and rockets are a hoax. It explained how rockets can't fly in space by today's technology, like reaction engines, solid fuel, or thermonuclear technology.

I told my father whom is a chemical-biological engineer, and never saw the man with that expression on his face... just went blank for 5 seconds and then tried to figure out how it is possible for the fuel driven technology to produce and induce movement in perfect vacuum and total lack of gravity or other type of electromagnetic field....

The video is no more on youtube, but fund out some other material.


La la la la lie...
Actually rockets work better in vacuum than in an atmosphere because there is no pressure outside the nozzle to push against the exhaust lowering it as a result. For upper stage engines the nozzles are generally longer to get more thrust and efficiency than in an atmosphere. They can continue to obtain thrust down the extended length since there is no external pressure to fight against. Here's a pic of the aft end of starship with 3 vacuum Raptors and 3 sea level Raptors. The nozzle difference is massive. 1741892124084.png
 
Ok, so did we really land on the moon?
There are many valid, accurate and incontrovertible technical explanations that cite all types of objective physical, photographic and technical explanations to "prove" that the Apollo landings really took place.
But my Go To piece of evidence that I like to cite for the conspiracy theory skeptics is to "Ask the Russians".

The Soviet Union at the time had the technical means to monitor the Apollo missions with radio, radar and optical technologies and their own intelligence gathering efforts.
If the US Apollo missions DIDN'T land on the moon, the Soviets would surely have detected this and made quite a propaganda stink about it.
The Russian's silence on the the subject provides sufficient proof involving a "conspiracy theory-like" explanation to silence most conspiracy theorists.

So use this explanation the next time a conspiracy theorist asks "The Question".
It will also save you time and effort in trying to explain technology and science clearly over the head of the person asking.
