I have this theory about time travel that the reason no one has figured it out is that once a person gets an idea about it in their head they get stuck on that idea and can't move off.
So I've decided to collect everyone's ideas on the way time travel would be done if it could be done and just try to keep an open mind.
That's why I'm here. Hoping to pick your brains, any thoughts you have are welcome...
Thank you. |

Regarding the past - what has happened in the past is determined and can't be changed. If someone were to travel back five years into their past, all they could possibly find is themselves exactly as they were five years ago. In particular, they wouldn't be aware that they had done it. This sort of consideration apparently led Roger Penrose* to wonder in his childhood years about the possibility of living the same ten minutes over and over again. If we did do that, we wouldn't know that we had done it.

Sorry I should have clarified. I'm not debating whether time travel is possible or not. That would take forever and lend little to the imagination.
The question is if time travel were possible how would it be done?
It's a test of your creativity to see if one can look past the realm of how things are to find the possibilities beneath. |

These appear to be two sides of the same coin. The how is wholly contingent upon the mechanism (is the mechanism) which relates directly to whether or not it is possible.

Time travel is possible! Yeah, we're doing it right now, we are progressing through time.
You have to rephrase your request as to how we think we can travel through time FASTER.

Universal Scientists had this pretty well covered a long time ago. The Universal Scientist took a lot of things for granted. So when individuals would ask could you time travel. They often left out the most important thing that was so well known to them. It is the spiritual factor.
A moment in time although measured and divided by the movement of objects in the solar system, relative to one another. Only on a gritty scientific level a mechanical level. But time is something more.
Could by the hand of God, the universe be resorted or rearranged so that everything was put back into place as it was at a certain moment? Sure.
However there is more then just the mechanics. There is the spirit in the individual. The individual was at any moment in time, in a certain place compared or relative to everyone else in the Universe.
His position, his frame of mind reflecting the happening just before that unique moment in question are unique. Everyone else at that precise moment also had a unique frame of mind different then everyone else in the universe. These moments cannot be duplicated. They cannot be postponed, they cannot be changed.
Not even God could alter this, by all that is known and taught of God.
I am sure God could erase all the evidence of our existence. However whom would wish this? Only someone with a very shallow existence. Time travel would be a very evil thing, making actions worthless, meaningless. Leave making your life worthless and meaningless up to law makers, they are true experts.
Sincerely,
William McCormick

There is only one form of 'time travel' which really isn't time travel at all. One can slow down their biological functions relative to the rest of the universe and "time travel" into the future.

Well, travel into the future is "easy." Just ask cosmonaut Sergei Avdeyev who has traveled 0.02 seconds into the future. Any decent space trip or simply surrounding yourself with lots of matter will hasten your journey into the future relative to outsiders.
Autonomous travel into the past, say a timeship, is looking grim for now. Via a continuously running time machine? Maybe. But Dr. Ronald Mallett doesn't have all the answers, and the community is still banging on that problem.[/url]

Time travel in both directions, perhaps in multiple directions, is theoretically possible, even by Einsteins' primitive explanations.
Future travel: Travel a distance enough distance at close to the speed of light and reutrn to your original start.
Past travel: Travel close to the speed of light near a black hole. The motion of spacetime + your relative speed of light speed will see others seeing you going apparently going faster than the speed of light.
So here's an idea for you to travel back in time:
Create a device that lets you move the spacetime you are hovering on, and in that spacetime go near the speed of light. I don't think spacetime has a critical velocity (aka the speed of light). To get spacetime to move though would be quite requiring a lot of energy. Perhaps you could harness the power of a black hole to do such a thing. They're already starting that soon at CERN, at least to make one. So why not.

Time is time. You cannot travel it or move through it. It has no dimension to pass through or escape.
You are part of a time recording machine. Your existence records time. You cannot undo what has been done.
You cannot even travel into the future. Those claims that someone has traveled into the future, are just very poor scientists misunderstanding the universe.
You can sit still while time passes or you can travel through space as time passes. It is really amazingly simple.
Sincerely,
William McCormick

The phenomena of time travel exists, and it has been proven many times. Even if there is something even bigger that we haven't noticed yet. Einstein was a very intelligent, fully logical viable scientist. Your statement basically placed him into your category, which I believe is not true, at least by recorded accounts.
My point:
Time exists and it is moveable within, at least forwards in time because we are moving in it right now, currently at 1 second per second. As CelticMadScientist said:
| Quote: |
| ...Sergei Avdeyev who has traveled 0.02 seconds into the future... |
This is stated by Wikipedia:
http://en.wikipedia.org/wiki/Sergei_Avdeyev
...which gathers it's information from various sources, as you can see as numbers 1 to 3 after it says 'reputable sources'.
| Quote: |

Yes, and I can also travel at 0.99c while time passes, but at a different rate to everybody else. And to travel through space is to travel through time, as they are both interchangeable. That is simple because it has been proven.
But your statement that you can travel through space as time passes is a more common day occurance isn't it? But I'm not fully sure what you are getting at here; please elaborate.
Faithfully (because I do not personally know you),
John Smith.

Plus, the GPS satellites have to take this relativity phenomenon into account just to function accurately. Just like with Sergei, take an accurate enough timepiece on a plane trip or into orbit and it will be slow compared to the ground clock on return.
I hadn't heard of the black hole past one; I'll have to look that up. That would be great.

Although much has been written about time from a strictly scientific viewpoint, such treatments never adequately deal with the more puzzling aspects of the time that confront everyone - what exactly is the "present"?, do events and objects cease to exist when they slip into the "past"?. As notions such as "past" and "present" have no definition within Physics, Physics can't be expected to provide an answer. (The view of time that I am attributing to Physics is what philosophers often refer to as "block time" and that is central to Relativity. According to this, time is a dimension which, along with three spatial dimensions, makes up space-time within which events can be assigned a position. There is no place in this description for notions such as "past", "present", "future" or the "flow" of time.)
These concepts appear to arise from the nature of human consciousness - the "present" is the moment when I am conscious and aware of things around me. It seems to be subjective. The "past" is made up of things I remember and the "future" is yet to come. Again, these are relative to what I regard as the present - there is nothing objective about such designations.
Regarding speculation about time-travel - if someone time-travelled from 2008 to 2020, they would regard 2020 as the "present" as that is the time when they would be conscious. They could not travel to a time beyond their own death as they wouldn't be conscious at that time. If the transition from 2008 to 2020 was made "in an instant", they could not have any recollection of events that occurred between those two dates. However, they should recall 2008. So, to get back to the original question, one way of achieving this would be put someone in a coma in 2008, keep them alive for twelve years and then, if possible, reawaken them in 2020. From the subject's point of view, they would have time-travelled through twelve years. What this ridiculous scenario is getting round to is that the way to accomplish time-travel is not to project the subject into space at speeds approaching the speed of light, but to tamper with their state of consciousness in an appropriate way. |
