My understanding is that every clock mechanism we have depends on motion of something w.r.t the observer. From atomic transitions to clockwork gears. So, does this property/constraint makes every clock available to use inherently susceptible to effects of relativistic motion?
For example, if you travel at 99% of speed of light with a clock, then there'd be some particle in the clock whose motion, w.r.t you, is also in the same direction, and when added up, it'll surpass 100%.
For above situation to be avoided, every particle that makes up the clock will have to be:
- Stationary w.r.t observer, but if this happens, the (frozen) clock can't tell time to the observer.
- Move in a direction other than that of observer's motion, If this happens, clock can't travel with observer.
Please help me out of this confusion.
