Temporal Novice
hi,

for practical/theoretical reasons lets just say i am new to this forum but i have always been interested in things like time travel and teleportation. So i do truly believe that all of these things will someday be possible but was just hoping for some incite from people who have delved into this field more then me. I have heard plenty of claims as to why time travel is not possible and even read up on theories as to why. But i was hoping some people here can give incite on to why they believe it is possible. I am not a genius with a large background in physics or any theoretical sciences but plz do not hold back or simplify your answer for me i will figure out what u are saying. Also i never really thought about this seriously before i always loved tv shows and such like doctor who and anime like seints;gate but never thought much of dedicating my life to such fields. I had a strange dream last night and lets just say i woke up with a new outlook i really want to get into this and learn as much as i can learn so plz post your thought here and thx.

 
Welcome...as Daver says read on the threads and ask whatever you want to know. I am not a genius, as you state, but I might know a few who can lend me a hand with some of the most difficult questions. So once again. welcome.

 
Is Time Travel Possible?

The answer is a resounding…maybe. The idea of time travel as a science fiction idea goes back a long time. The idea as a matter of fundamental science only goes back about 90 years, shortly after Einstein published General Relativity (GR). There are an infinite number of solutions to GR that depend on how one valuates certain variables in the equations and some of those solutions indicate the ability to time travel to the past. That doesn’t mean, however, that the solutions describe the universe that we live in. An example is in 1949 Kurt Goedel showed a solution based on a rotating universe which allows time travel to the past. It’s a valid solution in that the math is a correct statement of GR. The problem is that it doesn’t describe our universe. Rotation is absolute, unlike linear motion which is relative. A system with net rotation (angular momentum) leaves evidence of such rotation. Astronomers, cosmologists and astro-physicists have looked for 50+ years – the universe shows no evidence of rotation.

To date, the evidence, based on both theory and experiment, indicates that time travel to the past is unlikely.

 
Greetings all.

I too, am new to the forums, but let me put down what research I have done so far as far as time travel is concerned. Note that I am no scientist, I just kind of find out these things as a hobby.

Time travel may or may not be possible, for the moment, I don't really care. It is theoretically possible to send an electron back in time and, if you want, space as well. If an electron is hit by a photon, then it can be sent back in time. Thus, if I have the idea of EM waves down somewhat correctly, it may be possible to send yourself a text message or an email in the past.

Let us say, for example, that I find out the winning numbers for the lottery. I then write a text message to myself from somebody else's phone (It wouldn't work from your own). If one could somehow isolate these EM waves that were sent and then hit them with a photon (Beam, I'm not sure if it's a particle, or a group of particles... anyway), then you could send this message back in time. How far back in time, I have no idea, but the concept still stands. Incredibly roughly, I'll admit, but it still stands.

The idea came to me from a book I read entitled "In Search of Schrodinger's Cat". It went into a bit of detail on time travel on page 177. If you can understand more than me (which you probably can), it would be a good idea to take a look at it. It certainly gave me some form of idea about a different form of time travel that is rarely thought about.

Cave Ab Veritas.

 
You don't have to believe me but it seems as if a message was sent back in time to my phone and told me not to move to LA. I kept on getting messages when I was thinking of moving to LA and then when I said I'm not moving to LA anymore then the messages stopped. The messages were from an LA number.

 
Omoshiroi datta na....

Let us assume that these messages were indeed from someone in the future, not necessarily yourself, I would wonder why they would not want you to go to L.A. It is possible that, in another "World Line" (As is the preferred theory by both John Titor and myself, along with many others) you were killed, and a person who knew you very well managed to send a text message to the past. However, for you to send a text message to the future is an interesting idea indeed, not to mention that the person who had sent the texts would be able to know when World Lines changed. The idea is that the memories of anyone involved in a World Line change would be changed, if they even remembered. This means that either:

a) our idea of World Lines is false

b) the text messages were not sent from the future,

c) the person never received your text, but the very decision to not move to L.A moved World Lines, and you never got a text back because the World Line changed such that they didn't need to send you the texts,

d) the person who sent you these texts has found a way around World Lines usable by anyone and/or everyone, or

e) the person who sent you the texts has some form of special ability that allows them to know when and how time lines have diverged.

Whilst b seems the most obvious, especially for those who are sceptical, a and d seem more probable for the idea of time travel. However, the person would not attempt to change a future so drastically if it happened a long time ago. Assume your father died in a car crash when you were 20. 20 years later, time travel is introduced. Would you go back in time and save your father? Perhaps, though you would probably work on more things first. This means that, in all probability, the person who sent you these texts either already had the ability to time travel via messaging or created the ability using scientific technology. Thus, one can come to the conclusion that whoever sent you these text messages either:

a) really wanted you alive, despite the amount of years that may have passed between your death and time travel being introduced,

b) is a scientist, and created the time machine text messaging themselves somehow to keep you alive, among various other possible reasons, or

c) already had the ability to text message to the past.

These are all theories just based off if you died. Imagine the countless other possibilities that may have happened if it weren't death. Time is so interesting.

It was actually not a text but a phone call. The same phone call over and over. I pick up the phone and it sounds like a ghost moaning and only for a few seconds and then the phone call ended eacch time. I'm not meant to be an actor. That was why I was moving to LA at the time. It may have been someone that may have known me or a ghost. I really don't know. I just know that I should not move to LA.

 
Time travel may or may not be possible, for the moment, I don't really care. It is theoretically possible to send an electron back in time and, if you want, space as well. If an electron is hit by a photon, then it can be sent back in time.

I think you're refering to Richard Feynman's PhD dissertation that was advised by John Wheeler. Feynman eventually abandoned the idea of advanced-retarded wave electron-photon interactions...about 40 years ago.

 
@Darby

Yes, it was indeed Feynman's idea, thank you for reminding me of the name. Anyway, even though that idea was abandoned, it still allows the idea of a different type of time travel to arise. I mean, I would have never thought about messaging myself in the past if it weren't for Steins;Gate and the theory brought up there. The science, in my opinion, does not matter for now. What matters is what kinds of ways we can change the past and influence and/or visit the future.

@Skarpz

The concept of calling someone in the past has always seemed odd and almost ridiculous to me. To call someone in the past, this means that 2 timelines though in completely different years (Eg. Someone from 12th August 2012 calling someone on the 25th May 1997) must be in sync with each other. I cannot talk to someone who is not there at that moment, but at the same time, our 2 timelines are moving parallel to each other, and this feels like it could screw over time travel a little bit. I may have not made my point clear, but the point is that 2 timelines on completely different dates should not be able to talk to each other with no time delay, because their times are happening exactly at the same time, but at the same time, in the past/future of each other.

Jikan Yugami why do you repeat the message 3 times?
Or do you remember you have only submit the post once?

It is a glitch in the forum.@Jikan

There is actually recorded evidence that no one believes that someone was calling from 2036 to I think 1998 with perfect conversation. I would just have to find the recording again. "Power to the People"

Are you referring to some of those ridiculous YouTube videos of time travel proof? I'd like to hear this "evidence". I'm not sure how anyone would be able to prove a phone call is from any other time or world line. It's a voice on a phone. Unless you're skyping and the person you're talking to is standing in front of a visual landmark unlike anything we have. Just sayin.

 
If you limit yourself you will never achieve much. Theory is all about imaginative possibilities becoming real. Just as Science Fiction becomes Science Fact. Star Ships are being made right now and Star Trek will happen very soon. BUt you limit yourself and will never achieve anything if you can't think with imagination.

 
True, but still, having 2 World Lines going at 2 different years talking to each other for an extended period of time seems impossible, even by science fiction standards. I mean, it's one of the main things I don't understand about Dr. Who. Why doesn't the Doctor show up 2 days before he got the phone call and save the world a whole lot of trouble? Anyway, phone talking time travel seems like a bit of a stretch, but I'm ready to give just about anything a go.
