So with the tuning fork. It could be cold but if you gave it kinetic energy it would warm up so to speak?

Yeah, it would get hotter as the vibrations turn into heat, then the heat would radiate out into spcae

And if this happens on Earth it wouldn’t do it that much since molecules aren’t no where near as spread as in space correct?

Interesting… in fiction like Star Wars and Metal Gear Solid there exist “Vibro Blades” that vibrate so fast they glow white hot. So I know vibration creates heat but I didn’t know how it differs in space.
