Discussion Overview

The discussion centers on the possibility of reversing time through faster-than-light (FTL) travel, exploring theoretical implications and the relationship between time and speed as described by special relativity. The scope includes conceptual reasoning and hypothetical scenarios.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions whether time can be reversed if one could hypothetically travel faster than light, referencing the effects of approaching light speed on time.
  • Several participants assert that traveling faster than light is not possible, suggesting that this limits the discussion on time reversal.
  • Another participant emphasizes that time is fundamentally different from space, arguing against the possibility of reversing time.
  • A hypothetical scenario is proposed regarding the reassembly of a broken object when traveling FTL, raising questions about causality and the nature of time.
  • One participant challenges the validity of hypothetical scenarios that deviate from established scientific principles, suggesting they fall outside the realm of science.
  • Another participant introduces a distinction between different types of light speed, referencing Cherenkov radiation, but does not directly address the time reversal question.

Areas of Agreement / Disagreement

Participants generally disagree on the feasibility of FTL travel and its implications for time reversal. While some engage in hypothetical reasoning, others firmly reject the premise, leading to an unresolved discussion.

Contextual Notes

Limitations include the reliance on hypothetical scenarios that may not adhere to established scientific understanding, as well as differing interpretations of the relationship between time and speed.

Is it possible to reverse time?
According to special relativity, time slows down as one approaches the speed of light and completely stops when one travels at the speed of light, which is exactly ##c##. Then if one travels faster than the speed of light, is it possible that time will reverse or rewind ?
 
Physics news on Phys.org
One cannot travel faster than light.
 
Nor can time be reversed. Time is not space like.
 
I just proposed that in a hypothetical scenario, if one could travel faster than light speed then is it possible for time to get reversed ?
 
If, in your FTL time-vessel, you had broken a tea cup, when precisely would it reassemble itself? The arrow of time is the arrow of cause and effect.

If you're just going to make stuff up, you can make up anything you like. What would happen if squares had five sides? What would happen if people had wings? Unfortunately, when you do so, you have left the realm of science.

On that note, it is time to close this thread.
