Does a proton age differently when accelerated at high speeds?

Click For Summary

Discussion Overview

The discussion revolves around the effects of high-speed acceleration on the aging of a proton, specifically in the context of relativistic time dilation as experienced in particle accelerators like the LHC. Participants explore the implications of sending a proton at speeds close to the speed of light and how this affects its perceived age compared to a stationary reference frame.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions whether a proton accelerated to 0.999999991c would age differently after 5 seconds compared to when it was initially placed in the accelerator.
  • Another participant proposes that the proton would indeed be younger after the acceleration, though the difference may be minimal.
  • A subsequent reply clarifies that the proton would not be younger than its initial age but would be younger than the age it would have attained had it not been accelerated, suggesting a range of ages based on relativistic effects.
  • Further confirmation of this idea is expressed, emphasizing the distinction between the proton's age upon removal from the accelerator and the time it would have aged without acceleration.

Areas of Agreement / Disagreement

Participants generally agree on the concept of relativistic time dilation affecting the proton's aging, but there is some confusion regarding the specific comparison of ages before and after acceleration. The discussion remains somewhat unresolved as participants refine their understanding of the implications.

Contextual Notes

There are limitations in the discussion regarding the precise calculations of time dilation effects and the assumptions made about the proton's initial age and the exact nature of its aging during acceleration.

Very quick question here that's bugging me.

I go to the LHC and send a proton around at 0.999999991c. After 5 seconds of that speed I stop it and take it out. Has the proton become younger or older, by x years, than when it was put in?

Thanks!

After doing a little thought experiment I conclude that the proton sent around the accelerator would indeed be younger...not by much mind you, but still, younger...am I correct?

Yes!.. Wait.. No! Not younger than when it entered the accelerator! But younger than the 5 seconds it would have aged if you had not put it into the accelerator. For example if the proton was y years older when you put it in, then when you take out it will be younger than (y years + 5 seconds) old, but older than y years.

YES! Thats exactly what I was getting at! Thanks so much!
