Can a Pocket Watch Keep Ticking at Light Speed?

Click For Summary
SUMMARY

The discussion centers on the theoretical implications of a pocket watch traveling at light speed and its ability to keep time. Participants assert that as an object approaches the speed of light (denoted as 'c'), time appears to slow down relative to a stationary observer, a principle rooted in Einstein's theory of relativity. It is established that photons, which travel at light speed, do not experience time, leading to the conclusion that they do not "tick" in the conventional sense. The conversation emphasizes the impossibility of such scenarios while exploring the nature of time and motion in the context of fundamental physics.

PREREQUISITES
  • Understanding of Einstein's theory of relativity
  • Basic knowledge of the speed of light (c)
  • Familiarity with the concept of time dilation
  • Knowledge of fundamental particles, specifically photons
NEXT STEPS
  • Research Einstein's theory of relativity and its implications on time and space
  • Study the concept of time dilation in high-velocity scenarios
  • Explore the properties of photons and their relationship with spacetime
  • Investigate the implications of traveling at light speed on physical objects
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the fundamental concepts of time, light, and relativity.

if you have, let's say, a pocket watch. and somehow using and infinite energy, it travel at a light speed and still working properly. now if relatively to us, is the clock ticking.

Questions involving physical impossibilities don't have any answers.

It is an impossibility to answer, but we can answer the next best thing, which is what happens as we approach that condition.

If the stopwatch is moving but you are not, you will observe its time slowing down. The nearer it approaches c, the slower it will go.

(Thus, if you wished to extrapolate that to the speed of light, you can probably deduce the result, though, as chroot says, it's physically impossible.)

This is relativity 101. Any primer will answer most of your questions.
 
There is no question mark. THIS IS NOT A QUESTION. It is another poem!@! The second in just a couple of days.

So much wonderful literature,
here in theory development.
 
sorry Locrian, just the punctuation and please also forgive my 'wonderful' spelling and grammar.

what i am actually thinkin is that if the clock stops ticking, it mean's that for a photon there is no 'time'. and when there is no 'time' then a photon cannot move. and are all about talking about C. can anyone explain that ?
 
"for a photon there is no 'time'". Ding!
"and when there is no 'time' then a photon cannot move." Bzzt!

Photons do not experience time. They do move - at the speed of light. You cannot think of them like normal particles that experience a change in position over a length of time. They are a fundamental particle and they are tied up with the fundamental speed of light and fundamental spacetime.
