Time Travel?

Question

Do you think that if time travel ever becomes possible in the future that we would know about it now? If time travel is possible, then someone from the future would have come back to the past and we would then know that time travel is possible in the future, right? I'd like to hear other thoughts on this.

Answer 1

Let's put it this way: people make the same arguments about aliens. If there was intelligent life, we'd already know because they'd visit us, right? But for that argument to work, it assumes a LOT of things:

- INTEREST. Maybe travel travel is possible but people from the future are simply not interested in the time periods you and I are familiar with. For all we know, we are the chronological equivalent of the middle of the ocean, or any other place that simply accumulates no tourists.

- RECOGNITION. Even if there are millions of time travellers, we'd never know about it unless we were able to recognize them as such. If a time machine looks like a ballpoint pen, a person could even carry it around and have no idea. If time travellers could look and act like us, how would you know who was one and who wasn't?

- ACCESS. Who is to say that time travel is completely unlimited in its application? Maybe travellers can only go to certain years, can only watch and not interact, or can't go further back than when their machine is first built (this last limitation is suggested by physicists who work on time travel). If travellers can't travel anywhere, then that's another good reason why we might not see them.

- UNUSUAL TIME THEORY. A common conception of time is as a line. One-dimensional. But what if it isn't? If time has two or more dimensions, then it's possible for an INFINITE number of timelines to exist. Paradoxes like you see in movies would be impossible - every travel event would just open up a brand new timeline. Even with travel, then, there would be many, many 'original' lines with no apparent travellers.

...and that's just a few options. Our understanding of physics doesn't currently rule time travel out... but it is probably a bit much to assume that we'd know about it if it were possible.

Peace.

Answer 2

ah, I to had the same thoughts and often thought it was a paradox. I later realized that if time even does exist in a way that the future is going on right now, that when time travelers go back to the past, they would have to travel to our exact milisecond (or however small time breaks into) of time for us to even have a chance of meeting a time traveler. Also, the rules for time travel might forbid travelers from interfiering with the past. Or, mabey the technology is available but only used by the government to carry out certain tasks. Time travel most likely can't exists because more likely then not, time doesn't really exist. Just an invention of humans to keep track of things, which makes a lot of sense.

Answer 3

If I had a time machine here right now, and stepped inside and turned the knob back 10 years and hit "go", I would be in a dark area of space where the solar system has not moved to yet. On TV and the movies, they apparently think the universe is static and not moving. But our plant/solar system/galaxy is traveling quite fast.

But lets just say that I could go back to where the earth was located. Wouldn't my existence in a time that I didn't exist actually create a new continuity ( the previous continuity that I knew of being destroyed)?In other words, history is made anew from the point that I arrive in time. Thus, the previous inhabitants of the old continuity would not realize it because we have a new branch in the time line.

Answer 4

I guess after the time travel journey that someone from the future becomes a can food in our present time. What I meant to say this it is just impossible in physics. Maybe in computer you can do that. You can create a virtual world and go back & forth in virtual time. But here in reality it's just not possible, and scientist and already said that. I got the virtual world thing from a time travel tv programe.

Answer 5

Well, they would probably send him off to a mental institution, or they will never allow time travel in the future.
1. Because it could rip the very fabric of space and time itself, thus destroying all forms of life.
2. Some dumbass would come back from the future just to pantz george Bush in Public or some stupid **** like that.
So, I think they would pretty much outlaw that. Because some douchebag would end up destroying the entire universe.

Answer 6

here is the answer
if a person from the future visits the past then the future would change(as he was not there before) this could cause a change in the future and most probablly he will not do the time travel and since he didn't do the time travel we are back to square one where he visits us from the future

so what happens is that the whole universe is caught in a giant loop and the time does not progress beyond it

therefore time travel is a dangerous issue
(they look good in movies but not in real life)

Answer 7

If someone from the future ever "came back" then all that would happen is that we would put him in a straight jacket and send him off to the mental institution, because it is highly unlikely that the majority would be able to comprehend such a concept. Look what they did to Jesus, for heaven's sake. Even if God himself stood before us people would say it's some kind of hoax and scientists would rush to disprove it.

Answer 8

well there are a few theroes of time travel. one that the past is already fixed and cannot be changed so you dont have to worry.
but if it is not fixed like that then if the traveler does not make a gigantic entrance when s/he comes back in time full of sparks and xplosions then no one will belive him, and off too the looney bin

Answer 9

I in many cases want floor holiday, yet for long journeys, air holiday is a lot speedier, so i'd desire to apply it if i'm in a huge hurry. i've got moved from the East Coast to the West Coast, and one in all these holiday takes approximately 4 or 5 days with the aid of automobile, if i don't end long everywhere, yet there's a lot interesting ecosystem alongside the way that I miss with the aid of air holiday.

Answer 10

Couldn't really travel backwards through this time stream, but you could travel sideways through other dimensions/universes to a dimension that appears to be behind our current time.
