Please can you explain the concept of precession. Why do protons in a magnetic field that are 'off balance' start to precess?

Are the protons in my body precessing right now?

or avoid them, slow them, etc.
We can (somewhat) predict them, see them coming, see them destroying and then weep, but will our technology be able to suppress or control climate to this extent?? Or does it already?

I like science fiction movies involving space travel. Almost every space movie however has sound in the vacuum of space. But you need an atmosphere or air for sound. Is it possible for there to be sound in space if for example a rocket fires in space? The rocket is introducing gases into the vacuum allowing sound to travel through the medium. Is this the case? Would a spacesuited astronaut near a vector jet firing 'hear' the jet?

Also in a part of space with a lot of nebular or intersteller gas would there be some sound?

Can anyone explain this? I know that their mother wouldn't have the missing vertebrae hanging around in her womb for 5 years, because that's impossible, but this seems more than just a coincidence...

(In case you're curious; my aunt, 5 years older than my mom, with her one missing vertebrae, is short and always has neck & spine problems. My mom, with her extra vertebrae, is tall, and deals with scoliosis...)
