Main Question or Discussion Point
I am sorry if this is a weird or stupid question, as I am currently in college and majoring in physics, but have not taken any physics classes yet. The weird thing I was thinking about was the impossibility of perpetual motion. Are not atoms a form of perpetual motion? What about solar systems? I am not asking this to be controversial or anything of the sort. Im just trying to learn a bit more. Thank you so much for any input.
