Possibility of time traveling

  1. Jun 29, 2011 #1
    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.

    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)


    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? :tongue:

    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;
