Thank you! This was a mind-opener. I knew I was missing something and you gave an excellent explanation!

Can you explain what makes the problem chaotic in nature? I'm a software developer and I understand that a physics simulation might not be deterministic due to floating point math etc, but I also know that if I take a bit of special care I can program fully deterministic physics simulation in a sense that it will repeatedly give me same results.
So I can't wrap my head around why a 2-body problem is not chaotic and will always run the same thing at, but 3-body is not? What am I missing?

In space the theoretic best performance would with a nozzle of an infinite size/length, so the real size comes from a tradeoff between performance and mass.
In atmosphere the size is heavily limited by the atmosphere itself as pressure differences between inside and outside of the nozzle would destroy the nozzle structure.
For example the planned Starship upper stage by SpaceX will have two kinds of engines and nozzles.

You must be mixing up 96 kHz and 96 bit? A 24bit audio would already give you dynamic range of 144 dB, so "96 bit" audio must be a mistake. If I'm wrong I'd be really happy to know a use case for 96bit audio! :)
