I once actually thought that when movies and shows were developing, I thought that they were being made within the year of their release date. I didn’t know that these projects were sometimes done in advance or took years to make.
That when ‘Commercial Breaks’ happened during shows, I thought they meant that the actors needed a break before resuming. Not realizing that episodes are already made and commercials just interrupt things to just sell you shit.
When I learned food and drinks were energy for your body, I actually thought that when I got sleepy or tired, I just needed to drink or eat something. Not realizing that it wouldn’t have mattered.
I mean, it’s kinda true. A rocket just makes fire which expands and pushes whatever it burns out to make it go fast. You got the fire, the fire pushes things away from whatever you’re burning and the rest is just optimisation.
If you manage to make a helium balloon that floats in the air, attach a burning log fire to the bottom of it and enclose it in a way that the air intake is on the top and outlet is on the bottom you’ve made an engine that you just need to aim with a ballast weight.
Still wrong, but you were onto something.
Its upside down you know. The rocket engine fires upwards and what you see is after it pushes back, Newton’s First Law and all that (equal and opposite reaction).
If it pushed down, it wouldn’t work in space cos there’s nothing for it to push against.
