Can a Pocket Watch Keep Ticking at Light Speed?

Click For Summary

Discussion Overview

The discussion revolves around the hypothetical scenario of a pocket watch traveling at the speed of light and whether it would continue to tick from the perspective of an observer. The conversation touches on concepts from relativity, the nature of time for photons, and the implications of approaching light speed.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant posits a scenario where a pocket watch travels at light speed and questions if it would still tick from our perspective.
  • Another participant asserts that questions involving physical impossibilities do not have answers, implying that the scenario itself is flawed.
  • A different participant explains that as an object approaches the speed of light, time appears to slow down from the perspective of a stationary observer, referencing principles of relativity.
  • One participant interprets the scenario as a poetic expression rather than a scientific inquiry, suggesting a focus on theory development.
  • Another participant reflects on the implications of time for photons, suggesting that if a photon experiences no time, it cannot be said to move in the conventional sense.
  • A subsequent reply corrects the previous statement about photons, clarifying that while photons do not experience time, they do move at the speed of light and should not be thought of like normal particles.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the question posed, with some treating it as a legitimate inquiry into relativity while others dismiss it as physically impossible. There is no consensus on the implications of time for photons or the validity of the original scenario.

Contextual Notes

The discussion highlights limitations in understanding the relationship between speed, time, and the behavior of fundamental particles like photons. The assumptions about time and movement at light speed remain unresolved.

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.
