Hi there

  1. Sep 4, 2016 #1
    I am a Brazilian Mechanical Engineer working in the Supply Chain area. Also, very enthusiastic about physics. Hope I can contribute to the discussions in this forum.

    My very first question is "What is the present time". I read a lot that time is a human perception, so, if this is the case, how are all of us synchronized in the same moment, or we are not????

    It we are all synchronized, then, there would be no time travel at all, because the only existence would be in the present.

    Best regards,

    Hi Olaerte, welcome to the forum!

    Please note that this is introductions only, questions need to be posted in the appropriate forums. Please be sure that you read the global guidelines first, https://www.physicsforums.com/threads/physics-forums-global-guidelines.414380/ then any additional rules that might be posted in the forum your question would go in. We have a niche in only discussing known mainstream science here, speculation that falls outside of this is not allowed here. :smile:
