Waspie_Dwarf Posted May 21, 2014 #1 Share Posted May 21, 2014 Skinny wormholes could send messages through time Like some bizarre form of optical fibre, a long, thin wormhole might let you send messages through time using pulses of light.Predicted by Einstein's general theory of relativity, wormholes are tunnels connecting two points in space-time. If something could traverse one, it would open up intriguing possibilities, such as time travel and instant communications. Read more... 1 Link to comment Share on other sites More sharing options...
Taun Posted May 21, 2014 #2 Share Posted May 21, 2014 (edited) So you send a fiber optic line back to a distant ancestor to get them to do (or not do) something... Someone else sees the end of the optic line just hanging in air, and blinking a light... "Demons!" "A Witch!"... Your ancestor is burned at the stake and/or hung, you cease to exist, and therefore never send the message, therefore your ancestor is never killed.... or alternatively: You send the line back to yourself, to give yourself some lottery numbers (or or do something else I suppose)... Your earlier self sees the line, manages to read/understand the message: Earlier Self: "You want me to what?" Later Self: "Buy a lottery ticket on May 22nd use these numbers......... Okay?" Earlier Self: "No really! Who is this? Bob is this you? Are you messin' with me?"... Later Self: "No No... This is me.. Uh... You.. .Uh.. Us... I'm just in your future!" Earlier Self (making a raspberry sound): "Yeah Right. Say this wire thingy might make a good fishing line." Yank... Actually Waspie, the article was pretty cool...

StarMountainKid Posted May 21, 2014 #3 Share Posted May 21, 2014 Taun's examples are great, but if the earlier self won the lottery he wouldn't need to send that message to his past self, he'd already have the money. 3 Link to comment Share on other sites More sharing options...

Hugh Posted May 21, 2014 #7 Share Posted May 21, 2014 Time travel paradoxes, don't you just love them. Perhaps wormholes can only be between alternate timelines, thus avoiding the paradoxes. 2 Link to comment Share on other sites More sharing options...
bison Posted May 22, 2014 #8 Share Posted May 22, 2014 In theory, there are both time-like, and space-like paths through a wormhole. Near-instantaneous communications in a single time domain might be possible. Since wormholes are thought to be ephemeral, perhaps a packet system, something like that used on the internet could be employed. A tiny piece of a message is sent through one wormhole, the next piece through another, and so one. The pieces are then reassembled at the receiving end.

Or would we not receive anything until we invented it. Perhaps. Mankind didnt invent worm holes or the speed of light so its possible that events in time are being broadcast by nature, so only natural that we might be recieving them. 1 Link to comment Share on other sites More sharing options...
Mikko-kun Posted May 25, 2014 #11 Share Posted May 25, 2014 Nice... what if it's sorta symbiosis between influences of the past and future? If both past and future are in a state of constant change and not static still in their "freezed time"? 1 Link to comment Share on other sites More sharing options...
highdesert50 Posted May 26, 2014 #12 Share Posted May 26, 2014 Transition from a linear to an exponential growth of human knowledge is believed to have occurred, and knowledge is currently doubling about every twelve months. Does this argue that solution to the complex issue of time travel will have occurred sometime in the distant future? If so, where are the artifacts? Or, were we smart enough in the future to not the tamper with the past? Or, do we even have a future? Paradoxes, indeed. Link to comment Share on other sites More sharing options...

CaptElnadi Posted May 27, 2014 #18 Share Posted May 27, 2014 I believe, the more interesting question to tackle is: how do we detect signals sent by our future selves or aliens through wormholes as part of e.g.the SETI project Link to comment Share on other sites More sharing options...

I doubt it's possible too, but that we haven't heard about it from future people could have any of a number of causes and the trick still be possible.

StarMountainKid Posted May 27, 2014 #22 Share Posted May 27, 2014 An elementary particle, say a photon, has a trajectory into the past and also a trajectory into the future. Another example would be a car traveling down a road. We know where the car has been a minute ago (trajectory into the past) and we know where the car will be a minute from now (trajectory into the future). In this sense, the future must already exist for the car to be where it's going to be in the next minute. This is is a way of looking at space-time. The future space must exist for the car to exist in it's future trajectory, and the time dimension must exist as well for this future position in space to exist. This is the concept of space-time. Space and time work together to produce reality. If we plot this car space-time event from past to future, we observe the whole of this space-time event. Only considering the car event as occurring in the present moment and in the past, we are only describing this event partially. We must include the future of the event to completely describe the car event. My point is, in this sense, the future must exist in reality, and if communication by wormhole is possible (sending messages through time), then this possibility is real. The only problem is do wormholes actually exist, and if they do, finding one. Link to comment Share on other sites More sharing options...

The only problem is do wormholes actually exist, and if they do, finding one. Or perhaps by 'moving forward in time' the car is actually stretching space/time to include it's current location and it's temporal trajectory... As all things would do just by exisiting... Sort of creating time by traveling in it... 2 Link to comment Share on other sites More sharing options...
bison Posted May 27, 2014 #24 Share Posted May 27, 2014 (edited) For a space-like path, the key to selecting the direction of the point at which the signal or space vessel re-enters normal space might lie in choosing the direction from which it enters the wormhole. We tend to visualize a wormhole as a three-dimensional tube attached at either end to a flat plane, which is supposed to represent normal space. In fact, space is bridged in all three dimensions. There are no fixed entry and exit points in 3-d space. If no other factors interfere, it seems reasonable that the direction opposite of the point of entry is the likely exit point. The distance between entry and exit points is another interesting problem. This closer the path passes to the singularity, the more space is warped, and presumably the greater the distance that is bridged.

We know where the car has been a minute ago (trajectory into the past) and we know where the car will be a minute from now (trajectory into the future). The Heisenberg Uncertainty Principle does not allow you to know this information for wave/particles. You can not precisely know the trajectory. 1 Link to comment Share on other sites More sharing options...
