What do you think and/or believe about Time Travel?

Question

To the past. To the future. What are your stances and justifications/defenses? Closed causal loops? What about the Grandfather paradox. What about branched timelines (like in Back to the Future...and how would you get back to the one from which you came?) Are they plausible and/or possible?

What does it mean (in all aspects) in the theoretical situation of a book being written, then being 'destroyed' over time, but then someone re-interprets it and sends it back to the past-from which the 'original' is written. Where did the information come from? What else is involved?

Do time travellers to the past have 100% free will; what about ones into the future?

Do you believe/think that the future is both unchangeable and has already 'happened'? Perhaps we are just waiting to enter into the next predetermined moment/event.

I am no hard determinist though...however I believe it slighty changes during time travel.

Answer 1

It is nice to imagine that you can travel back into past and future too.

Answer 2

It may be possible,,,

Someday...

Answer 3

Time travel is possible because of time differences, but it is limited untill the certain range of time ( 1 day = 24 hours ).

For example :  to travel into time ahead (future) we fly from Germany to Perth ( 00:00 Germany = 07:00 Perth ). to travel into time backward (past) we fly from germany to New York City ( 06:00 Germany =  00:00 NYC )

Is that what you meant? Isn't it cool?

Answer 4

I think that it is possible but at this evolutionary state in our technology (and as a species) we aren't capable of understanding how to manipulate the dimensional planes.

Go to www.johntitor.com for some REALLY neat time travel stuff. He explains how we have multiple timelines due to the 4th dimension being the realm in which linear time is fragmented into basically nanoseconds and you can hop around in each of those tiny moments with a powerful enough Celsium clock mounted with magnetic generators that fold the third dimensional space into a pocket. Then you can then punch a hole through the aether and move around in the 4th dimension as you hop from timeline to timeline (with some degradation of percentages, depending on how far back in time you go, that the timeline you come out in can be different from the one you came from - I.e. solving the "problem" of the Grandfather Paradox). He spoke about CERN back when it wasn't even a penstroke on a blueprint and said the technoloy and information CERN gives up will help us harnass enough magnetic energy to propel someone through time. He speaks a lot about dual singularity black holes because that's the best comparison and possibly explaination he has to the force it would take to go aether-skipping. This is before anyone even found evidence of the existence of dual singularities. There's a lot of interesting things he discussed in terms of physics that have only recently been discovered. Go to the site and all of the questions you asked will be answered...and they actually make sense from a logical and seemingly intelligent perspective! I've been a Titor-ite for years!

Answer 5

Travel to the future is possible, Einstein proved this.

Travel to the past is impossible, thermodynamics proves this.  There are irreversible processes.  The energy involved to reverse time would have to be greater than the energy available.  Not only would the energy EXPENDED suring the process of time have to be replaced in order to reverse the energy loss, but additional energy must also be supplied in order to reverse that process.  Similar to activation energy in a chemical process.  However, since the time traveler is included in the system, that additional energy is not available.

Think of it this way:  Suppose you and your time machine wanted to travel back in time, let's say 1 day.  In order to restore your surroundings to the original state as it existed one day ago, you would have to have sufficient enrgy to reverse the motions of every subatomic particle.  You would need to reverse the motion of the earth, the sun, moon, stars....  You would have to reverse the flow of every photon which struck you or your machichine in the past day.  You would have to reverse the flow of every memory in every individual EXCEPT yourself.  And so on.

However, IF you accept teh possibility of parallel universes, where there exists a separate timeline in each universe for each and every possible outcome at each and every moment in time, then "time travel" may be possible by tunnelling to a parallel universe which, by one set of possibilities, just happens to be exactly one day behind us with exactly everything else being the same.  However, that would not actually be time travel because you LEFT this universe and became a part of another.  The universe you LEFT would continue on from that point on, without you until you managed, somehow, to return.

The future is mostly unknown.  The past is unchangeable.

Oh, I am also Christian.  God will not allow it. ;-)  

Answer 6

I think time is a concept that humans don't fully understand. It's artificial.. in that we use clocks and calendars to monitor the passing of time. We try to make it absolute, however, time is relative. There is no single absolute point for time.. it's a continuum that has no bounds. I think time travel, in the sense of our perception of time, can only exist when we build a vessel that can go faster than a million times the speed of light. This would allow humans to essentially "stop" time, and virtually live in a timeless environment.

Additionally, I believe the equation for time is equal to a million times the speed of light divided by space, where space is a physical object measured in any unit.

Answer 7

Time traveling probably doesnt exist for a reason.

It would be amazing to go back and fix mistakes,

but we'd never learn anything if we didnt make mistakes.

Who needs to go to the future?

Thats no fun if you dont experience things in between.

Answer 8

I think time travel is plausible if it's short units of time like a day or so, but decades I don't think it's possible. No proof has ever been revealed to make me think otherwise.
