Sleeping is a means of time travelling,
Time goes by real fast when you're kipping.

Yes, as we fall asleep, we briefly enter the hypnogogic state, which is a form of entrancement, where we are still conscious, but some of our mental faculties are not in use, such as our perception of time.

And also as we wake up, we pass through the hypnogogic state where, we might say, we are mildly awake, but not quite asleep.

And normally, just like sleep, we enter and leave entrancement all during the day, and we take it for granted, and it is something we are not immediately conscious of.

However it is possible to take entrancement into our creative hands and design our own entrancements for specific purposes.

To learn how to design our own entrancements a good place to start is The Way of Trance by Dennis Wier.

The ways of the INTP usually helps me enter this trance i.e. being lazy.
I'm quite unconscious of time i.e. feels like 10 minutes has past however in reality it's been 4 hours.

Yes, it is very likely you are in a trance. And indeed you may be susceptible to trance. This is like a kind of a gift and it can be used for good ends. On the other hand, it can become addictive and out of our control.

If you are introverted, it may be a way for you to avoid the stresses of the day. However you can take control of this by learning how to systematically relax. A good place to start is Relief Without Drugs by Ainslie Mears.

And once you have learnt to systematically relax, you can learn to create your own trances for your own purposes. A good place to start is The Way of Trance by Dennis Wier.

I think time travel is possible, but a good fictional novel to read about this is Three Days to Never by Tim Powers which is a book about how Albert Einstein invented time travel but the project was so confidential that not even the president knew. Yes, it's only fiction, but it's a whole world of possibility.

I voted 'yes' on the poll.

From the point of view of Relativity time and space form a manifold. So to speak of time travel we assume time and space are separate. This is an old idea made obsolete by Relativity.

So in this thread when we speak of time travel we are speaking about a fantasy.

This is no surprise as both mbti and astrology are based on fantasy. But relativity is based on fact.

Of course we prefer fantasy to fact because we want to titillate our desires.

In so much that time is a construct, the US government makes us go back an hour every winter. Always hated the concept of messing with Father Time though. The time zones are equally annoying. Apparently, the human brain cannot handle waking up at the usual hour and seeing it is still dark, so we have to mess with time as a whole country, so we can feel better. :huh:

And what about the leap year extra day! Where the hell did it come from? Again for expediency and so as to not have to think outside the box (can't be expected to handle the irregular 1/4th extra day the lazy earth takes to do its routine rounds around the sun), we have found a way to make time out of thin air every four years!

It does not fit into the corporate 9 to 5 scheme either. Would it be a holiday or would we get paid? This is more important that nature's our, well, rhythm. Never mind what exists, we will pretend it doesn't so we don't have to deal with something not standard issue. ;)

So I can totally see us traveling back in time in the future. If a giant international political fuck-up occurred that taxed our collective brains too much, we will all agree to go back a year and decide that it never happened!

Open your mind to view the evidence recorded and ask yourself; Ancient Aliens? or Time Travel from NASA?
Roswell's little space men? or Roswell's time machine?

Be open minded a bit and you'd realise time travel is indeed a thing.

To follow up on @<a href="http://www.typologycentral.com/forums/members/27162.html" target="_blank">Cloudpatrol</a>'s thread I felt I shoułd ask you all if you think that it's even possible to travel through time?

I time travel all the time, I get up in the morning and before I know its the evening.

We travel forward in time all the time, and the faster we move in space, the further we move forward in time, but quantum mechanics says we also can travel back in time momentarily because of the Uncertainty Principle. We travel back and forth in time but only on the quantum scale. And it is important to remember a quantum is the smallest anything can be.

Traveling backwards in time would be like hitting rewind on a movie. The characters, supposing they were conscious, wouldn't experience anything remarkable whatsoever. Only an outside observer would notice that time had been set to an earlier date. Since there is no observer outside the universe, this amounts to saying that traveling backwards in time is fiction (unless it happens on a strictly local scale and is observed by someone). The past is and always will be permanently what it is.

According to Einstein, history can be envisioned as a static, 4-dimensional structure. Past events are located in one place within time space and future events are located in another place within time space. Since all of these futures, pasts, and presents exist always and simultaneously, it can be deduced that it is owing to the observer's viewpoint that we're at this point in time space rather than in all of time space. Since it is purely a matter of one's viewpoint, traveling to the past should be possible. But to do so would, like hitting rewind, produce results that make no difference to the time traveler.

When people speak of time travel, they usually mean stepping into a situation that looks exactly like the past would have looked and either setting a new course of events into action or producing a history identical to the one in their past. That can be done, but it isn't really time travel; it's restructuring matter to look like it did in the past. It would require highly advanced technology to do such a thing on any appreciable scale, and due to the second law of thermodynamics, it would be impossible on a universal scale.

An outside observer of the time travel being someone that is not participating in the time travel themselves? Are you saying then, that the traveller themselves would be exactly as they were in that past event with no recollection of the future that they came from and thus would just act out the past the exact same way they did the first time?

But if the time traveller is inserting themselves into that point in space time, wouldn't their interactions with people that are in that past cause a different future to branch off. I'm not comprehending the concept of it "just like hitting rewind" because in this hypothetical scenario, the time traveller is travelling to a past that they aren't in. The past version of themselves is already there, and if they interacted with their past selves or anybody else in that past, then would that not propel them into a different future?

If one moves backwards in time and interacts with people that are in that part of the time-space, how could that not create a new future? You have hit the rewind button, but when things start moving forward again, the interactions with the time traveller and the people in the past are different because they should have never been there. These new events then, would create a slightly different present and a different timeline altogether.

To both questions: yes.

If they literally went to the past, then no. The time traveler would act in such a way during their stay in the past as to create a history that leads to the present in which they time traveled. Imagine someone who uses a time machine to carry the blueprint for the time machine into the past, and this blueprint is then used to build the same time machine that the person originally used. Eventually, if the person lived long enough, they would be able to witness their past act of traveling back in time performed by a younger twin of themselves or in other words the person that they were before they traveled back in time. This is the consistent histories version of time travel, and it simply means that the time travel has already occurred when the person travels back in time. What the person did in the past in the third person they will now do again in the first person. *spoilers for Harry Potter* This is what occurs in Harry Potter and the Prisoner of Azkaban, if you've ever read that book.

If it created a new future, it would mean that there are multiple universes and that the person had traveled between them (this is because time space is static and unalterable; the original timeline would consequently have to be somewhere within it), or that the person had simply traveled into a scenario that happens to resemble the past. That isn't truly the same thing as time travel.

Apparently, time travel, even backwards, is mathematically possible. Here's an abstract of a paper published in Classical and Quantum Gravity by Tippett and Tsang

Traversable acausal retrograde domains in spacetime - IOPscience

In this paper we present geometry which has been designed to fit a layperson's description of a 'time machine'. It is a box which allows those within it to travel backwards and forwards through time and space, as interpreted by an external observer. Timelike observers travel within the interior of a 'bubble' of geometry which moves along a circular, acausal trajectory through spacetime. If certain timelike observers inside the bubble maintain a persistent acceleration, their worldlines will close.

Our analysis includes a description of the causal structure of our spacetime, as well as a discussion of its physicality. The inclusion of such a bubble in a spacetime will render the background spacetime non-orientable, generating additional consistency constraints for formulations of the initial value problem. The spacetime geometry is geodesically incomplete, contains naked singularities, and requires exotic matter.

The problem seems to be that the exotic matter required to curve the space-time is hard to come by.
