Rockets need an atmosphere to propel

you are a stunning example of the dunning kruger effect in action

I guess that’s why glpers cannot prove rockets working in a vacuum with simple experiment

...explain the satellites we see in the sky, they are way too distant for jetliners. (as in, they are visible to viewers 200 miles apart)

swamp gas and weather balloons



regardless.....

sats aren't in 'space'

LEO

Low earth orbit

Low earth orbit is still well above the internationally accepted line of space and not all satellites are in low earth orbits.

But still not in a vacuum even higher than LEO... is it?

Oh for the Apollo days again!

Well if you my initial post before assuming, you would realize I am not refuting the lack of oxygen for combustion.

When you assume, you make an “ass” out of “u” and “me”

Even low earth orbit is a harder vacuum than any vacuum chamber on earth, so yes, it is. There is no "absolute" vacuum anywhere in the solar system, there are always a few particles everywhere you go, but for all intents and purposes, yes it's a vacuum. Are you really this ignorant?

What is your definition of "space"? There is actually a "boundary" for it, as define by the experts. What is your definition of LEO?

If I was as fucking stupid as you I'd shoot myself right in he kisser.

Moron.

Thanks OP, we now have two NASA theories that admittedly cannot be demonstrated with a simple experiment:

- gas pressure without containment
- rocket propulsion in a vacuum
- next?

Wrong.


Also wrong.

When it comes to space... yes. My physics teacher was a sadistic bastard that used to hit us with rulers! Biology was ma thang...

Still want to see a bottle rocket in a huge vacuum

Low earth orbit IS space. So is geosynchronous orbit.

Done.

And done.

Exosphere!

Is still thinner than any vacuum chamber on earth. It's still space.

Again practical experiment that an average person can do would be adequate

Well then it's a good thing that we already have a massive experiment being done with a huge ass rocket actually in space right before our eyes.

Indeed I agree. There is no force in space working against the rocket so obviously it would be propelled by the rocket engine. What does it even matter? Why not conduct an experiment to disprove something useful?

The rocket goes horizontal and it is not evidence that the rocket was thrusting in space. Your other video is a simulation, which is not evidence of reality. The only evidence you have is full of Controversy and questions

I just proved that there is no opposite force resulting from movement due to pressure differential with the pipe experiment. Now you have to prove that there is, otherwise rockets don’t work in space.

....And Jet engines really run on compressed air......

That's how you get to orbit. The fact it turns around, nulls its horizontal velocity and then comes back to land next to where it started proves very much that it did indeed have thrust in space.


The other video is an open source simulation, an in silico experiment based on very simple physics. The source code is right there, so if there's something wrong with it, it's up to you to show where.

What if it never went to space and just came back down?

Wow, thanks for proving you didn't even watch the damn video. You're willfully ignorant, you're not even looking at what I'm showing. You really don't get it.

yup...

i gotta say after reading whole thread imho everyone is kinda right, and wrong, including OP on both counts.

Iff rockets were ever to go to 'space' (as space is defined by NASHA and other space agencies), who knows what would happen? Nobody does, because nobody is able to do so or conceive of it, because it simply DOES NOT EXIST. Nature DOES abhor a vacuum. So do imaginations, it is inconceivable. People are very creative though for sure, clap clap all around, and the rest are... well...




sorry, not trying to offend anyone, conversation here has been great, except the senseless and meaningless insults tossed around here and there. it's a small world after all...
