The problems with time travel: Was Einstein right?
We have moved to new forum software and posting here is closed!
PLEASE BOOKMARK THE NEW FORUMS
All speculation...hence Speculative Vision...
Why am I posting here...? @_@

So how do we travel backward through time? For the moment, I don't believe in that. And I'll say it again: I hope there is no such thing as backwards time travel.
Posted By:  Hyperion Aug 16, 2004 - 03:13 pm |       | Eventually I think man will create a computer or AI capable of at least computing a possible outcome of any one event to an almost 99.9% probability.
Quantum computing, once hit, will set us of in that direction for sure.
I am not saying however, that, that entity or machine, whatever, will process the computation of that event to a mathematical certainty, but rather to within a 99.9% probability rating. So that a person could take a judgment based on the computations made, and be more or less certain of the outcome.
IMHO I think that we, man, will get that far in the science of prediction, which is in a way related to forward time travel.

| Posted By: Kevin Sep 19, 2004 - 07:36 pm | | What I know about time travel:
In order to travel through time, you must create a rip in time's fabric. You create a wurmwhole by positioning a most effective pattern of lasers strong enough to create a wurmhole, and then you can enter, but there is no telling where you will exit. Of course, there is no proof that wurmholes exist, but it is more than possible, and it would explain a lot of phenomena that occurs in the universe.
In order to stop time, you must accelerate to the speed of light. Why? Because your biological clock only has so many ticks, and in order for it to tick, it must move from point A to point B. So if you travel fast enough, point A and B will be a longer distance to make, as it's always moving farther away. Your biological clock moves at exactly the speed of light, so if you were to travel at the speed of light, then your biological clock wouldn't be able to tick, thus you will not age, and it will seem like you are travelling into the future because you will remain exacly the way you are, while the universe changes around you.
Our biological clock moves at exactly the speed of light? Now that's something I didn't know. I finally got into physics because I decided to read this book... unfortunately, the book is 20 years old. It says that the internal clock slows down, but it doesn't say that the clock stops entirely. Based on what I know, it seems unlikely that the clock stops completely, so could you enlighten me?
This is what I think based on this book: space-time is relative... The farther a galaxy is away from another, the faster they move away from each other... Therefore there must be galaxies that we could never see because they move faster than light away from us. But that also means that our galaxy is itself moving faster than the speech of light away from other galaxies... We are moving at the speed of light - but only relative to something so far away. So I don't think that the internal clock actually stops, but it is relative. And I also get the impression that a black hole moves at an infinitely slow speed compared to us, but that it doesn't mean its internal clock stops. I could very well be wrong.....
Now that I understand exactly what the fabric of space-time is... a wurmhole makes some sense to me. I believe it's proven that we can warp, bend, space-time to get to a different place... It seems that there would have to be a 5th dimension if we would be able to warp into the past. But warping a 3D object into a 4D place seems like trying to warp a 2D shadow into a 3D star - not a good analogy, but I mean it just doesn't belong there. If we could bend space-time to get to a place in the past, that is still going forward.
Okay, this is getting weird, so I give up for tonight.

Thats were we get all relevant info on things like our body clock and so on.
At the quantum level everything moves, nothing is certain, that one fact has thrown lots of spanners into the works of more popular theories, such as speed of light, time travel and the laws of physics.
Just thought I would a little bit of info

There once was a young man from Bright
Who could travel much faster than light
He departed one day in the relative way
And returned on the previous night!
Not to further complicate an already very confusing and speculative topic, but it seems as though some of the latest developments in string theory (a.k.a. 'matrix theory'; a.k.a. 'membrane theory') may have implications for the questions surrounding the practicality of time travel. I haven't yet familiarized myself enough with this field of research to be able to comment further. I am aware that there are detractors to this whole approach at attempting to develop a new cosmology
The likes of Sir Isaac Newton, Sir Rutherford and Albert Einstein stride like gods among the men and women of our race who throughout time and from all corners of the world have sought to advance our understanding of this universe, this world, this realm within which we find ourselves to be residents. Whether some of the individuals today who are working in the new physics of string theory will tomorrow take their place in the Pantheon of Science remains a big question mark.
Over time the vast accumulation of scientific facts and figures is daunting. However as Einstein himself stated, the one faculty that is of primary importance in discovering Nature's truth's is also that which is indispensable for an understanding of her larger purpose and design. Thus the human imagination is the ultimate doorway whose threshold, once traversed, becomes the portal to a new reality of greater scope and dimension than that which is circumscribed by the limitations of an exclusively objective and reductive science.

Well, now... I didn't understand what Kevin was saying last time I was here... Now I do. I've been thinking about "parallel universes" lately and have come to truly understand them.
Based on my new understanding, this entire thread makes sense. So backward time travel would be an entirely different thing from going forward. It would not affect our own universe as it does not seem possible for a roundtrip, which has already been pointed out. ••••, I'm slow! 
Okay, one more thing I thought I'd bring up while on the subject of universes... I wonder if there could be a universe that works at faster than our speed of light... But this would be a fundamentally different universe that would probably be far beyond our imaginations.
