    Physicist suggest that some type of wormholes may stay open long enough to send a photon through.

    Of course if you read the article you would see they emphasized that this of course theoretical, but it's Interesting nonetheless. The fabric of space and time is far beyond my mind but I don't think it's too far fetched to believe in this stuff. One interesting theory my friend had when he was completely baked off his ass was that ufos are just us from the future. But if we are able to travel into the future or the past why haven't we seen anyone from the future yet? Time blows my mind sometimes
     
  2. What does the fabric of time consist of?
     
  3. What if we have seen them? Would people from the future look different from us? And if they introduced themselves to us, wouldn't that mess up time and space as we know it?

  4. It is impossible to travel in time, because time does not exist. Time measured in our own solar system movement. In other words, the human has invented a time. Only to facilitate better understanding. And these days it help us lot..

  5. Still is possible it just means we move past our definition of time faster then what it passes on earth.

    Could be.. who never know.. :)

    even if we have invented the concept of time, we should be able to travel along the path of time although it's not a physical object. 
    traveling in time may not mean relocating your body, rather rewinding or fast-forwarding reality around you.

    Interesting aspect. And quite complex  :lol:
     
  9. there is a lot of things we don't know for sure though yet.

  10. Its simple. We all exist in different places but in the same moment. Theres no such thing as moment travel.
     
  11. We can only imagine.

  12. This is a complex question. There are a couple theories out there and some allow it and others don't General relativity for example doesn't allow it in reverse but does going faster into the future. String theory allows time travel also as it's a theory of everything, including time.

    You're speaking as if it doesn't exist because we "made it up". We make up lots of things. Time is a very very well defined concept. It is a property, same as length. Length and time are two aspects of the same thing. geometry in a continuum.

    Nature doesn't allow it to go backwards....errr....logic doesn't allow it to go backwards. Time isn't something that acts on "things", it is a geometric property. Age (seperate from time) is just historic fact. It doesn't "un-do" lol it just....continues.
     
    No "backwards / forwards". It's the 4th dimension. i.e. impicilt in all other, or in other words in all directions. It sounds retarded to word it out but
     
    time "moves forward" infront of you just the same as it does behind you...infact it "moves forward" everywhere.....it's better said as it's a continuum.
     
    When you start a stopwatch, which way is the time going? Where is this time that you are measuring? in the clock? in space? hopefully you are begining to see it doesn't make sense to give time such a direction. entropy has a direction...time (spacetime) does not.
     
    The final word is time has a direction no more then length has a direction. It's funny, in that once you understand the concept of spacetime. Travelling "back in time" would require the Length equivelent to "backwards" time...whatever that maybe. But surely "backward" length sounds kinda fucking stoopid.
     
     
     
    A basket ball bouncing up and down is the exact same seen reversed. Time doesn't care if it's the floor pushing the ball up, or the hand pushing the ball down.
     
    The physics are all the same.
     
    What cannot happened this for the flow of energies to reverse (this is what you mean by "back in time") It is simply to much to ask all of the universe to reverse itself back to a certain entropic state just to appease your "backward" time travel ideas.  ahahahaha
     
    Now if you want to comparatively slow down your physical proccesses the universe couldn't care less. That's your issue to accomplish, but don't think you can go asking it to do everything that has every physically happened backwards until time xyz.
     
  15. Check this out:
     
    We're time traveling right now...
     
  16. If we invented a vehicle that can travel at the speed of light, and we would not disintegrate in it, then yes, time travel is possible.
     
  17. I think if we went back in time, the langoliers would get us

    I feel pretty confident to say actual time travel will never exist. The now is now and anything that has already happened has gone. The only way time travel would be possible is there was some sort of hard drive that stored our universe with all the information of our entire past. I think it would only be possibls if there was a god who designed some sort of recording device and has s record of everything weve ever done.

    That isn't to say we couldn't find a way to travel forwards in time. Like cryostasis* or some machine that would step out of time as we know it and pop back in whenever they feel like. But thatsbprobably what the extent of time travel woild do

    locally (look up physics definition if you don't know it), we can DEFINE a "now", however this is by definition only. There is no physical "now" just an approximate HERE & NOW. i.e. coordinates. 
     
    motion "skews" comparative measures of length/time. In other words "skews" comparing "now" moments. 
     
    "The only way time travel would be possible is there was some sort of hard drive that stored our universe with all the information of our entire past."
     
    Regarding your comment above, i've got one question; SSD or disk?  Joking aside, in what way is the universe itself not the most obvious "record" of everything that happened?  Of course me, my body is part of the sum of everything that has happened. From stars exploding to Earth cooling on and on through every event up to me here.
     
    Time is not itself linear, however the sequence of physical happenings is ABSOLUTELY and forever in a order everyone in the universe would agree on....when & where each event happened there would be much dispute. But not on the "Historical order" of the happenings.
     
  20. Technically it is already possible to time travel, space travel IS time travel.

    Depending on whether you're moving closer to or further away from the point where the universe began (one theory is the Big Bang), that's traveling backwards and forwards in time because you're traveling through spaces that have existed for longer or shorter than Earth.

    It would be very minute unless you travelled huge distances, but still, it technically would work.
