Do you think time travel will be possible in the future?

Question

Do you think time travel will be possible in the future?

Answer 1

time travel to the future can be done by speeding up to relativistic speed. time travel to the past may violate causality so no.

Answer 2

No.  If it were possible, there would already be time travelers from the future, don't you think?

.

Answer 3

No. We are responsible for all our actions and will be held accountable. There is no changing this fact.

Answer 4

A simple test:

Step one: resolve to devote your life to building a time machine

Step two: promise yourself that the first thing you'll do when you succeed, is to come back to this point in time, and let yourself know it worked.

Step three: wait. If it's possible, your future self will arrive to tell you so in fairly short order. If you fail to show up, time travel is impossible. That, or you're just not bright enough to make a functioning time machine...

EDIT: it's worth noting that I, myself, am currently travelling forward through time at the rate of one second per second. I suspect you are, too. So in this limited respect, time travel is, indeed, possible.

Answer 5

No, time travel could cause destructive changes in your own history, simply by doing it at all you are transposing the atoms that made you personally, into a different location than they should have been at that point in your history and so you'd immediately annihilate yourself (and possibly change a heck of a lot in between too).

And that's before taking into account that if you did that, then you wouldn't exist in the future to do it at all.  The situations are mutually exclusive, thus time travel doesn't make sense unless we have causality horribly wrong, which is rather unlikely.

Answer 6

Probably in a Temporal way.

Physically moving through time in an accelerated manner would smash our frail bodies.

In a way we already do travel in time, just not the way you mean.

Answer 7

i doubt it

Answer 8

I think it will be possible in the past...

Think about it...

Answer 9

Yes.

Answer 10

if it were possible, we be having people from the future coming to the past(our time).

Answer 11

No, here is why.

Even if time travel is physically possible it is self defeating. Neglecting time travel into the future which we are doing right now kinda time travel into the past affects your present no matter how small the change. The chaos theory or the butterfly effect both state that minute changes of initial conditions can gravely change the outcome of a system and this applies to time travel.

Lets say I go back in time and kill my grandpa, then I will never exist and will not travel back in time to do it again (or for the first time depending on how you look at it). If I do something very small like squash a butterfly that will affect the entire butterfly population and maybe the flowers in my garden won't get pollinated and die. Now this is hardly much of a change, but it will affect my journey back in time. Now maybe I am a little pissed off this journey back because my flowers died so I stomp on the butterfly a little sooner than I did in the previous journey. This barely affects anything, but it does affect my journey in some slight way. Lets say after 1 billion cycles of going back in time I swat a mosquito that would have given otherwise have given malaria to a Libyan who was going to kill Doc Brown who built the time machine... all of a sudden the journey cycle ends and time travel is not achieved. Even if someone later designs a time machine it will end in failure because journeys into the past will evolve over the changes of the past to the point where some crucial detail leading to the machine's design will be adverted. The only way out of this loop is for a very rare situation to happen where the time travelers actions don't affect anything at all that will affect your journey... not even a difference between journeys as small as a displaced atom in the air can exist. If this occurs than the cycle will be broken and to an omnipotent observer unaware of journeys in previous time lines it would almost appear like your actions in the past caused your journey in the first place.

If time travel does turn out to be possible than the universe is a much weirder place than many would hope.

Answer 12

you'll feel dizzy after you arrived to other destination

Answer 13

For those of you pointing to Einstein's theory of general relativity.  If you travel at the speed of light You are not going into the future.  You are bending space and time differently than those who are not going the speed of light.  This has the effect of speeding time for people left behind or slowing down time for those who left. Hence why its called relativity its relative to the viewer.  Now the closer you approach to the speed of light the slower time is for you and the faster is for everyone else.  It is an infinite relationship where time never stops nor does it exist at all points at once but you would keep inching towards that theoretical boundary never reaching it.  This is explained to the best of my abilities and there are probably physicists on this site that could poke holes in everything we have said but my description is as general as I can make it

Answer 14

nahh

Answer 15

If we could in the future, then we always have been able to. People from the future could come to the past and show us how to do it. The fact that we are not overrun by visitors from the future is pretty good evidence that it is impossible. Not proof, but good evidence.

Answer 16

The first law of thermodynamics says that matter can neither be created nor destroyed. The amount of matter (energy) in the universe cannot increase or decrease. If time travel were possible, then the first law of thermodynamics is wrong. When you go back in time you increase the amount of matter in the universe. Not just in the past, but also in the present, and the future. How you might ask? If I go back in time don't I decrease the amount of matter in the present. Actually you increase the amount of matter both in the past, and the present.

Think of it this way. Let's say that I have one dollar, and a time machine. I can't hardly live on one dollar, and I want to keep my time machine all to myself, so I come up with a brilliant plan. I take my one dollar and send it back in time 5 minutes. Five minutes in the past I take the dollar out of the time machine and I now have two dollars. Five minutes later I take the two dollars and put them in the time machine and send them back five minutes. I now have four dollars. I keep doing this until I have as much money as I could possibly want. I have just created matter, not only in the past, but in the present, and the future. My one dollar has magically turned into millions of dollars. But unfortunately I have broken the first law of thermodynamics, I have created matter.

The first law of thermodynamics does not allow time travel. If you can get this law repealed, then time travel might be possible.

Answer 17

The only way I see time travel being possible is traveling into the future.  The faster an object travels the slower time moves for that object.  This is a proven fact.  In the future if we are able to travel at the speed of light, when we come back to Earth, 80 years will have passed when for the person who traveled it could be only a single year.  In this respect traveling to the future is possible, but not to the past.

Answer 18

did you just watch that show about the lady going into the past to kill baby hitler?

good show.

Answer 19

actual time travel bring,s up the old paradox problem. let,s say you travel to the past & meet a man [ that just happen,s to be your great,great grandfather] ..you have an argument & accidentally kill him. if that happened then you could never be born to go back in time in the first place..the same apply,s to the future..you could change someone else,s past...so it seem,s unlikely ..but not impossible..professor einstein believed that it was unlikely but believed that time viewing was a very real possibility...transdimentional travel would be a more realistic possibility...as far as light speed [ mentioned above]...the theory is that time slow,s as you approach light speed , actually stop,s at light speed , then begin,s to regress as you exceed light speed...but only for the person traveling at that speed. but you would have to be pure energy to achieve faster than light speed...this is only a proposed thoery....at this time nothing we know of can exceed light speed.

Answer 20

I heard that time travel is possible. One person's explanation for this was when something is moving fast enough (even your hand), you can see the past. You can see the past because your hand was moving so fast you could still somehow see it moving a tad second before.

So, I heard, it's probably possible to at least somehow get back to that before point in time. How? I have no clue.

Answer 21

I hope so, not so that I can change the course of history, just so that I could catch a glimpse of a now deceased family member. I wouldn't make my presence known or anything cause that might change something and effect the future, just to see them one more time.

Answer 22

Didn't I just answer this or was that a trip into the future ?
