Airplanes are turbines (a spinning blade) they push air, submarines are also turbines (a spinning blade) they push water. Rockets are NOT turbines, they do not push anything.

But... thrust occurs because rockets expel material out the back (gasses resultant from combustion)... It's not like they are pushing air or something. Vacuum or not has no bearing on whether or not thrust happens.

The above video is stupid.

Gasses resulting from combustion that can't happen without oxygen in space. But the photos we see from NASA clearly show flames in environments with no oxygen. Oops. I'm sure you'll have something to say about liquid oxygen, but I won't see it because I'm not interested in your insults or childlike mentality. Make sure you upload photos from all your journeys into space for future generations.

Rockets use chemical oxidizers rather then gaseous oxygen for the combustion. While liquid oxygen is an option, storing it is energy demanding and as such it's a bad option. That is circumvented by the use of ammonium perchlorate.

I didn't say YOU were dumb, just the video. I'm sure you are just confused like so many others in the modern world.
