Satellites Do Not Exist

Regarding the "rockets need atmosphere to push against" business. It seems to me that for modest expense, a garden shed scientist could set up an experiment to show that the entirety of the world's scientific community is lying and that the heroic truth seeker is correct.

One could get a vacuum pump/bell jar set up, like any school science department would have.
Place a Catherine wheel firework inside, along with some sort of r/c way of igniting it.

Remove the air from the bell jar using the vacuum pump and then ignite the firework.

The fibbers at Nasa, ESA et al would have you believe that the firework would spin regardless of nothing to push against.
Of course, this would be shown to be a lie and the entire "history" of space exploration would be exposed as a decades-long international con job.

I wonder why they don't try something like that.

Ha, the fireworks would push against the side of the bell jar.:eye-poppi


(I have seen this argument against that experiment)

Mythbusters already did that

I've just been out and had a look at that high-flying shiny plane.
It's incredible how they manage to fly it over at exactly the same time as the sheep are expecting the "Space Station".

Cool! Hadn't seen that one. The irony is that rockets actually work more efficiently in a vacuum. I can't wait to share that with someone who claims rockets don't work in a vacuum, then watch him make some excuse for why he still isn't wrong.

"That video PROVES they don't work in a vacuum! See all that smoke the fuse emits before the "rocket" ignites? It's pushing against the smoke!!!"
 
It has always made me wonder how these idiots who think that rockets won't work in space because there is no air to push against, can reconcile that with supersonic missiles, that obviously do exist.

If rocket motors required air to push against, then the reactive force would diminish as the rocket got faster because there would be less air pressure, since the rocket is travelling away from the air it is supposedly pushing on. Once the rocket got to mach 1, there would be nothing left to push against, so mach 1 would be the speed limit, and no additional thrust could make it go faster.

Correct me if I'm wrong, but I understand the International Space Station is visible with the naked eye, isn't it? How would these nuts explain that away?

"That's no space station, that's a second moon!" ~Star wars spoof... :D

I went searching for the Stundie thread that I was recalling and it appears that the idea that rockets fly by pushing against the atmosphere, and thus won't work in a vacuum, is distressingly widespread in some circles.
Rockets, propellers, they're pretty much the same thing, right?

There are plenty of people hating quantum mechanics.

There are quite a few who doesn't understand thermodynamics.

But the rejection of Newtonian mechanics, that was a new one for me!

So we could fart our way into orbit?

I did the math for my son once, just because we could.

Conservation of momentum is a bitch. Even if your gut could hold 25 bar and your rectum was a de Laval nozzle, you would not even get airborne.

We did not do the math for farting at relativistic velocities.....
