Re: Time Travel - should we?
iron25 if someone had the capability of it then they would know how to rule the entire world, or start wars and conflicts and win them, becuase if things were pre-determined then he or she could travel back make changes, fast forward to see what happened and so forth.

Atoms age, right? So, if you travel back in time the atoms that make up you (the time traveller) will be older (and therefore different) to those atoms currently making up the you in the past. |
Re: Time Travel - should we?
Okay Earth and our entire galaxy is moving through the universe at some unknown high speed, if we went back in time how would we know we are gonna land in the correct space on Earth if its moved.
However if we are going back in time are we going back in time through the universe as we shall see the universe as it was say 40years ago? Going on them lines the power required to create such a rift would likely be enough to make man able to travel to the stars, as if you can rip the space/time continuem apart to go back in time then likely you can rip it to move through it forward to a distance keeping the time/space similar, because as Einstien said so I believe ( need to research this bit ) That at the speed of light time stands still so it would bring a new era of space travel and time travel. Sorry for mindless drivel space travel is something I am getting big on :) |

I have a headache :dozey:

Re: Time Travel - should we?
*laughs*
It gets a headache with the discussion of energy drives for a space ship to be propelled at speed of light year after year. Long running thread on another forum to end all threads where I visit. |
Re: Time Travel - should we?
Apparently, some scientists now think that time travel is possible, but you would not be able to do anything to change the future:

Simply trying to make it easier for you to understand.
They relate the switch to the peaks and troughs of quatum waves back and forth through time - which do you think is easier to get your head round. |
Re: Time Travel - should we?
I think time travel might be possible through time manipulation, where by you cheat time in some way making it move faster in some way. For example putting yourself in a deep freeze where a computer takes you out the coma after specified time and you wake up the moment you goto sleep gives you feeling you skipped time, on this theory only going forward would be possible.
If someone went back in time to change something, eg. to stop hitler make the mistakes that lost him WW2, then I believe we would see something like whats explained in back to the future 2, multiple time lines. People in the current would carry on living their lives as normal in their timeline, the person changing history then changes the timeline hes in, so effectively going back creates a new timeline. However I would say that only works when going forward in time and not backwards, reffering to back to the future 2 again, when marty goes back in time he sees himself from when he first went back in time and he sees the grandpa guy from when he went back in time, when really he should be going back in time on his current timeline, when the grandpa guy went back in time he would have created an alternate timeline on my thoery so marty would never have seen him and only his other self so when going to the future again things would still be normal. So my thoery to summarise if going back in time was possible, people would never see anything change in the current as the result because when going back in time a new time line is created, and the results of a new time line will only be seen from then onwards going forwards not back. Also a weird question to ask, if the universe is infinite wouldnt the concept of a wormhole be impossible as you cannot fold a infinite peice of paper. |

Re: Time Travel - should we?
Like all things, time-travel has its positive side and its negative side.Here are some examples, not in any paticular order.
Some of the positives are:- a) printing of a list of the UK lottery draw results and going back a week at a time to buy a winning ticket...ditto for horse-racing/shares/other forms of gambling b) rescuing species that have become extinct and getting their DNA samples c) helping to prevent personal & public disasters of the past and the future d) getting copies of all the freeware that's disappeared off the net e) recording copies of rare or popular TV programmes for DVD issue today f) saving public records and famous artefacts which were lost or destroyed in the past g) saving people's lives by taking modern medical techniques, equipment, knowledge, drugs back into the past h) helping the people of Africa to develop an infrastructure which keeps them from poverty,famine, disease and ignorance i) recording the lifestyles of the past for historical preservation j) becoming a time-travel agent organising trips to the past And on the negative side:- a) repairing one incident which has a negative knock-on effect on others b) generating new timelines worse than the one you have "repaired" c) erasing people in the present and future by altering a fact in the past d) altering the past in such a way that the future technology which helped you to get there isn't invented, effectively trapping yourself in the past No doubt, other forum members can up with lots of other positive and negative uses of time travel. |
