"If you think you know quantum mechanics, you don't know quantum mechanics" -- Richard Feynman.

But this is an astronomy subject, involving classical physics, not quantum physics. When we tend to see the night sky as unchanging, forever constant, because nothing really does change. The stars are in the exact same positions they were a thousand years ago. The plants move with precise, clock-like regularity. But upon closer examination, we notice subtle changes. Supernovas, for example, occurring once every few dozen lifetimes. Last week's solar eclipse. A comet here, a particularly large meteor there. But upon even closer examination, the universe is full of change. Changes so violent they could vaporize our tiny planet with the merest exposure. But given the vastness of space, they are still few and far between.

Does the sun rotate? I dont mind asking stupid questions? :)

Do all stars rotate. All stars are made of the same stuff i would guess.

And that’s a complete guess :)
