Time travel

[Erfan]

tehRonskie, I saw you writing about time travel.

Time travel is one of my favorite topics! I wrote some time travel stories in junior high school that used a machine of my own invention to travel backwards in time, and I have continued to study this fascinating concept as the years have gone by.

We all travel in time. During the last year, I've moved forward one year and so have you. Another way to say that is that we travel in time at the rate of 1 hour per hour.

But the question is, can we travel in time faster or slower than "1 hour per hour"? Or can we actually travel backward in time, going back, say 2 hours per hour, or 10 or 100 years per hour?

It is mind-boggling to think about time travel. What if you went back in time and prevented your father and mother from meeting? You would prevent yourself from ever having been born! But then if you hadn't been born, you could not have gone back in time to prevent them from meeting. You are in a sertant and uknown conciousness mindfucking yourself..

Perception is an amazing thing; everything depends on how you look at things. As you seem to be an avid learner of time travel, I am at no capacity to challenge these thoughts. It definitely has me thinking though. It's quite interesting to say the least.

I've never really researched time travel, but it may be interesting enough to look into in my spare time. I've never thought about time travel in this way. More or less, the media depicts time travel as this simple thing that puts you in a different time period on demand. On a more realistic scale, we are all always travelling through time.

Hopefully this thread gets a burst of replies so that I can read up on it later.

Interesting comments guys! Personally somewhat related to time-travel is the notion of teleportation. I had a teacher once tell me that it could be possible to do these things that manipulate time and space.

The most challenging thing that would have to be solved is mainly how to deconstruct our genes and atoms and then reconstruct them to be exactly the same when we teleport. In terms of time-travel--I assume the process would be similar but it's interesting to wonder how you would actually be able to travel time in itself. XD Like Yankiee mentioned though, we are traveling through time now as we speak, I don't know if it's really possible to go back or forward though. Hmm...

Here's the question you should be asking: If you were approached with a situation involving time travel and all the components.. would YOU personally put yourself through it? (Assuming that there wasn't much experience with it; but scientifically it all made sense)

Time travel as you guys seem to put it seems unlikely. You can do some sort of time travel-like experiments already with relative velocities but it seems unlikely that time travel within our universe is possible.

As for the OP I think the fundamental concept of how time travel would work is misunderstood. If we were somehow able to travel back in time as it were the whole deal would likely be an instantaneous process and the end location would likely be in a different universe. There is no reason to believe that anything you did in said universe would affect the world you had left. Actually it is fairly preposterous to think that things would just poof into a different existence. It is fun to think about it like a jerk reaction butterfly effect in which you could go to pre-WWII germany but in reality the universe you were born in would almost definitely still have the same history.

And I think the thing that would be harder to accomplish than actually traveling through time would be doing it accurately. If you consider how vast the universe is and how many different moments in time you could arrive the odds that you could accurately arrive and land safely on a habitable planet somewhere is astronomically low. And if you want to do the same and want a universe with an identical copy of earth in the midst of an important historical event you’re really optimistic.

I think that science fiction has made time travel look to be a very linear process and overly romanticized, which is fun, but it has as much grip on reality as your average superhero movie.

On a sort of opinionated tangent I don't think the human race will ever succeed in time travel or even exploration beyond our solar system. I think it is pretty obvious that without doing so the human race will die off in a very sad manner. If we don't wipe ourselves out with some sort of dangerous weapon we will just milk out the last of the resources on our planet and eventually our technology will devolve and we will be back to a very basic form of survival. After a massive loss of human life and slow deterioration of the world we know today we will reach an event horizon in which we will be no longer able to pursue such possibilities as to travel through space and try to find home elsewhere. If this happens our world would just exist until either our sun red giants or aliens salvage our planet.

It's kind of sad to think that we aren't funding space programs anymore and I think if more people realized all of this we could accomplish so much more. Anyway this doesn't have anything to do with time travel other than that we would almost positively need to utilize black/wormholes to do so.
