"The relativistic analogy can be carried to its logical end. Since time begins to slow down with higher speeds, it can be shown that at the speed of light it stops totally and beyond that begins to run backwards!"
-- Albert Einstein
Is Time Travel Possible?
In one of the wildest developments in serious science for decades, researchers from California to Moscow have recently been investigating the possibility of time travel. They have realized that according to the equations of Albert Einstein's general theory of relativity (the best theory of time and space we have), there is nothing in the laws of physics to prevent time travel. It may be extremely difficult to put into practice; but it is not impossible.
-- John and Mary Gribbon
it would be possible to dive into such a black hole and through the ring, to emerge in another place and another time. This "Kerr solution" was the first mathematical example of a time machine, but at the time nobody took it seriously.
..... but physicists have always scoffed at the idea of time travel, considering it to be the realm of cranks, mystics, and charlatans, and with good reason. However, rather remarkable advances in quantum gravity are reviving the theory; time travel has now become fair game for theoretical physicists writing in the pages of PHYSICAL REVIEW magazine.
--Dr. Michio Kaku, Professor of Theoretical Physics at the City University of New York, is the author of VISIONS: HOW SCIENCE WILL REVOLUTIONIZE THE 21ST CENTURY and the best-seller HYPERSPACE
Various researchers have proposed ways in which backward and forward time machines can be built that do not seem to violate any know laws of physics. Remember that the laws of physics tell us what is possible, not what is practical for humans at this point in time. The physics of time travel is still in its infancy. While all physicists today admit that time travel to the future is possible, many still believe time travel to the past will never be easily attainable. Don't believe anyone who tells you that humans will never have efficient technology for backward and forward time travel. Accurately predicting future technology is nearly impossible, and history is filled with underestimates of technology.
On the other hand time travel into the future is absolutely possible... only problem is you can't come back.

You’re right, many do think it could it could be theoretically (mathematically) possible, but so far there appears to be no way to resolve the various problems it creates which include, in addition to violating the 2nd Law Of Thermodynamics, several parodoxes.
No paradox for time travellers
THE laws of physics seem to permit time travel, and with it, paradoxical situations such as the possibility that people could go back in time to prevent their own birth. But it turns out that such paradoxes may be ruled out by the weirdness inherent in laws of quantum physics.
Some solutions to the equations of Einstein's general theory of relativity lead to situations in which space-time curves back on itself, theoretically allowing travellers to loop back in time and meet younger versions of themselves. Because such time travel sets up paradoxes, many researchers suspect that some physical constraints must make time travel impossible. Now, physicists Daniel Greenberger of the City University of New York and Karl Svozil of the Vienna University of Technology in Austria have shown that the most basic features of quantum theory may ensure that time travellers could never alter the past, even if they are able to go back in time.

Both theories and experiments agree Time Travel is possible. It was suspected not predicted from Relativity that paradoxes would be given opportunity to arise , but Physicists have shown that Quantum Theory wouldn't allow any paradoxes to even arise.
In order to nessecitate the TOE here there would need to be a conflict between the two theories for instance if Relativity predicted that a paradox would happen and Quantum Theory predicts that they wouldn't. That would be a conflict that would require the TOE to resolve. However, paradoxes are not predicted by relativity so there is no conflict.
Relativity only predicts Time travel is possible which opened up speculation about paradoxes and Quantum Theory goes further to show that paradoxes would not even arise.

Your habit of stating conjecture as fact never ceases to amaze me and it appears you don't even realize you're doing it. You're grasping at straws. Go back and read the article you posted. Note it uses words like "may" and "could"... does that sound like fact to you? It's a just theory. Also, if you had actually bothered to read the actual paper you would have noticed this quote…
arxiv.org...
(Of course, there is an equally likely explanation, namely that going backward in time is impossible. This also solves the paradox by avoiding it.)
Now if we could somehow instantaneously break ourselves down into individual “bits” of information that describe the current state in space and time of every particle within us and somehow had a way to work with each of those “bits” to transform them and then used that modified data to somehow reconstruct ourselves them we might be able to do some cool stuff… I think
It was not my intention to prove or disprove the possibility of time travel into the past, or future for that matter. Since we seemingly as of yet do not know for sure. It was my intention to have ourselves analyze what possible results of the intentionality of the collective consciousnesses of the universe/multiverse, and the how cosmic politics would be effected, whether we were aware of such cosmic politics or not.
This thread may not reach the potential i was hoping for if all we do is debate the as of yet unprovable. I see and recognize the possibilities of the paradoxes. I have also seen theories that if you were to go back in time and kill the younger you, it would be the you of the future that would replace the you of the past, and you would simply be stuck in an earlier time. I don't know if i buy into that idea, but i thought it may be worth mentioning. I'm going to re-read the thread, and look into some of the ideas you guys present.

If I understand your question correctly, the answer to your first question is obviously yes. According to theory of relativity, time travel into the future is possible at or near the speed of light.

I'm sorry. I just don't think you are right. I mean, i am not travelling at the speed of light right now, and i am moving forward in time, am i not? Einstein and others such as Hawking state the exact opposite in fact. The closer you approach the speed of light, the slower time is.

I think we would strongly consider going back to witness the big bang, or aspects of it, going as far back as we could.
