Discussion Overview

The discussion revolves around the possibility of time travel as inferred from particle motion observed in the CERN particle collider. Participants explore concepts related to time dilation, the behavior of particles at high speeds, and the implications of these phenomena for time travel theories.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants suggest that particles in the CERN collider exhibit motion in time, questioning whether this could lead to practical time travel.
  • Others clarify that while particles experience time dilation, this is distinct from the concept of time travel.
  • It is noted that charged particles like electrons and protons can be accelerated to speeds close to the speed of light, but achieving light speed is deemed impossible for massive objects.
  • One participant raises a hypothetical scenario about time travel involving a time machine and questions the implications of such a scenario on causality.
  • There is a discussion about the challenges of accelerating large bodies to near-light speeds, with some participants emphasizing the difference between approaching light speed and reaching it.
  • A later reply humorously compares time dilation to homeopathy, indicating a mix of seriousness and skepticism regarding the concepts discussed.

Areas of Agreement / Disagreement

Participants express differing views on the implications of particle behavior for time travel, with some focusing on time dilation and others questioning the feasibility of time travel itself. The discussion remains unresolved with multiple competing perspectives on the topic.

Contextual Notes

There are limitations in the discussion regarding the definitions of time travel and time dilation, as well as the assumptions made about particle behavior at high speeds. The mathematical and physical principles underlying these concepts are not fully explored.

Who May Find This Useful

This discussion may be of interest to those exploring theoretical physics, particularly in the context of time travel, particle physics, and the implications of relativistic effects.

hi,


in the CERN particle collider they have found out that the particles are moving in time.can this concept be put to reality after studying the motion of the particles in the CERN collider

all answers are welcome

We are all moving in time.

Can you be more specific? Perhaps you should start by linking to an article that describes this 'moving in time' you speak of.

Well the particles suffer time dilation but that is a different concept from time travel. Are you talking about time dilation?
 
particle can be accelerated like electrons protons they are charged particles easy to accelerate so they can travel or suffer Time dilution
it's very hard for large bodies or impossible to reach speed of light

It is impossible for anything with mass to reach the speed of light.

electrons have mass and protons i know that they are in cern could accelerate protons
to reach 99 speed of light
can you Explain please

None of those particles actually got to the speed of light. So I'm not sure what further explanation that you want. Getting "close" isn't exactly reaching it.

Zz.
 
Just out of curiosity - If I built a time machine in 20 years, and then went back in time and gave it to myself 20 years earlier, wouldn't I have always had it? Meaning I wouldn't of had to invent it in the first place?

I don't think he's saying otherwise.
It's convoluted but read what he said again.

It's hard to accelerate large bodies to near the speed of light. (True) It's impossible to get bodies to reach the speed of light. (True)

particle can be accelerated like electrons protons they are charged particles easy to accelerate so they can travel or suffer Time dilution
it's very hard for large bodies or impossible to reach speed of light


Besides, he's talking about time dilution, which is a completely different question. :biggrin:

It was the "hard or impossible" that threw me. As for time dilution, is that like homeopathy for physics? :-p

Considering it is currently understood that time travel is most likely not possible this question cannot be answered. It's essentially asking "assuming impossible thing X is possible thanks to unexplained phenomenon Y how would X work?". However for your own interest here are some interesting links regarding aspects of time travel;
