Discussion Overview

The discussion explores the hypothetical scenario of stopping time and its implications for inertia and the behavior of objects, particularly focusing on whether inertia would be conserved or forgotten in such a situation. The conversation touches on theoretical concepts from physics, particularly relating to time, inertia, and the laws governing motion.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions whether inertia would be "forgotten" or "remembered" if time were stopped, and whether objects like bullets would fall from mid-air upon resuming time.
  • Another participant argues that stopping time is not possible and relates the concept to the principles of relativity, stating that all inertial frames have their own time and that massless particles cannot conserve inertia.
  • A different viewpoint suggests that if time stopped, light would not travel, leading to a lack of visual perception, although the participant expresses uncertainty about this reasoning.
  • One participant points out that inertia is defined as resistance to acceleration and questions its relevance to the scenario of bullets falling, implying a disconnect between time and inertia.
  • Another participant asserts that the premise of stopping time violates the laws of physics, suggesting that such a question is nonsensical within the framework of established natural laws.
  • A further contribution elaborates on the relationship between time and ordered events, suggesting that stopping time would prevent any motion or change, thereby limiting the concept of inertia to a standstill.

Areas of Agreement / Disagreement

Participants express differing views on the implications of stopping time, with no consensus reached on whether inertia would be conserved or how the laws of physics would apply in such a scenario. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

Participants highlight the limitations of the thought experiment, including the dependence on the definitions of time and inertia, and the inherent contradictions in the premise of stopping time.

Ok, if I stopped time, and started it again. Would all the inertia of everything be "forgotten?" Or "remembered?" Would bullets suddenly fall to the ground from mid-air? Do you understand me?

As much as I hate to admit it, I do understand you. :-p
Unfortunately, we can't stop time. If we could, I'd still be 25 years old. By relativity, all inertial frames have their own time. The only way to stop it is to travel at light speed. Since only massless particles can do that, there is no inertia to conserve. Time is more or less measured by the change of state of some system or other, so stopping it would by definition prevent any change at all from occurring. The closest that you can get is to take a picture of something. That's one instant of time frozen in place.
 
If you think about it, when you 'see' something, it's all about light hitting your eyes. So if time stopped, light would no longer travel and you would (of course, this can't happen as time's stopped for you as well) see nothing. I'm probably horrible wrong, but oh well.
 
Inertia is resistance to acceleration and its units do not include time - so what does that have to do with bullets falling to the ground?
 
Yes, if time stopped, laws of physics would indeed be violated. But this sentence is devoid of any meaning. Time not stopping IS one of the laws of nature, so it's like asking "If the Earth were flat, what would it be resting on?".
 
Falling of bullets back to the ground from mid-air is again an order of events ... whihc is titled 'time' again! ... STopping time would simply limit increase/decrease the fourth coordinate of the proposed space-time structure.Gained inertia maybe from a force or a collision , because the result of inertia is another 'set of ordered events appropriately responding to the action as per the laws of physics' , all these ordered events can perform each step of the order ONLY when the fourth coordinate time moves forward . Thus stopping time would simply restrict motion , bringing the object to a standstill.
