if a object is moving at or near the speed of light, not saying it can, but let's treat it as a thought experiment, then...

note that i dont know much about physics. if an object is near speed of light, is the object moving itself or, are the atoms bonded together that make the object moving?, if the object is moving, then the atoms should be not at rest and moving with the object as well, reaching the speed of light? (example, if a ball is moving near c, then are its atoms themselves moving a group or at rest since they are bounded together and not flying together)
