Poll: Time travel - will it ever be possible?

[FelixDeCat]

I think it might. But time travel will be so tightly regulated by government, it will never be generally available to the public and any private attempt to do so will be severely punished.

People always like to say "If there was such a thing as time travel we would see people from the future here all the time."

I look at it differently in few ways:

1) Time travel hasnt seemingly been invented yet because a future reality doesnt exist yet. In other words, to make make time travel possible you must have portals which exist within your reality and a future to travel from. Once a stable portal is created, time travel might be possible.

2) Time travel may only be possible in one direction, as it currently exists, that is - to the future only.

3) When you come from the future to the past, you do so in such a way as to be unseen, unheard or undetectable by anyone or anything in that reality. This might help solve crimes committed in the future as you could visit the past undetected and tell ?who did what?.

We may advance to the point where portals are unnecessary. You already know the government would forbid anyone from changing the past or perhaps even visiting. The government, however, may possibly change certain things all the time. If time travel is available worldwide then various governments might not allow you to visit their countries as you might corrupt their timeline

Do you see the problems we are facing? And this hasnt even been invented yet. Stupid government.

This is what happens when too many authors start turning their focus towards science fiction. :|

Even though Felix's first statement here:



<< 1) Time travel hasnt seemingly been invented yet because a future reality doesnt exist yet. In other words, to make make time travel possible you must have portals which exist within your reality and a future to travel from. Once a stable portal is created, time travel might be possible. >>



Makes quite a bit of sense to me, I mean, if we have different portals that do indeed exist, then they would be in a different time period, and the future does sound somewhat believable (I mean, it's not completely bazaar ).

Wow, can't wait until our technology really takes off so that all these questions would be answered - hope I'm still alive then

Humans will most likely be able to travel backwards in time. At the subatomic level, particles travel backwards through time routinely. It will only be a matter of time until technological advancements make it possible on the macroatomic scale.

Edit: oops.. I wrote backwords instead of backwards.

E=mc² baby. Although I'm not really a math or science head, something just tells me it is impossible to go into the past, but the future is a different story.

Going back to the past... hmm, that makes me wonder: which past?

If there is indeed an infinite number of possible timelines, traveling back into time would mean that you would end up in a different timeline.

BTW, particles traveling back into time is not comparable to a collection of various molecules traveling back into time, like the Human body. Also, if the only possibility to travel back into time is a CTC, then we can't travel back to a time for which there doesn't exist a connection to formed by a CTC.
Since the existance of 'natural' CTC's is unlikely, all CTC's will be artificial and only enable us to travel back into the past for a few decades or maybe centuries. Also, how would one get back?

Considering all those points forces me to conclude that not all of the past will be accessible, only the time since the invention of the first 'time-machine'.

The past in which we choose to visit?
