is time travel sci fi?

Question

is time travel sci fi? because every thing that was in some day scifi became true, like julio berne`s novels, do you think in a not so far future we can bent time and space and time travel?

Answer 1

Personally, I do not think that time travel is possible. My proof is a little shaky, but here it is.

Let's say that time travel is possible and that it *will be* invented at some future point in time. If true, where are the time travellers from that future point in time or later?

Answer 2

time travel does exist in theory the means to achieve it are beyond our grasp, the faster you move the slower time moves for you, NASA has proved time dilation through various tests on astronauts, at the speed of light time stops but only for the traveler,

to give you an example, a photon from the sun takes 8 minutes or so to reach the earth at the speed of light, but the photon is only a billionth of a second older than it was when it left the sun, so for that photon it would appear to have traveled 8 minutes forward in time , (a really rough example)

the other theory is with worm holes but with it being as tough as it is to open a prison, land fill or refinery in a community, you can see why it might not be easy to practice creating black holes near our solar system,

Answer 3

It would be just an opinion, since I am an amateur physicist and astrophysicist at the best.

This idea of traveling in Time is labeled "fantasy for the sake of the idea" at present because no one can see a way to do it.

Travel futureward has the potential of using some incredible machinery, power source, device yet to be discovered working to draw someone from earlier times
into the future.
This possibility, from the simplest no-return trip to the one envisioned by Edmond Hamilton in the great story "The Star Kings"--mind transfer, 800,000 years into the future and back--involves no temporal paradoxes; the traveler and anyone else exchanged are each in one place at one time; as a one-way mental trip there would not even be someone in the past to destroy elements necessary to the future.
The "Star Trek" TOS "City On the Edge of Forever", "All Our Yesterdays" and "Tomorrow is Yesterday" shows among others, featured this possibility in several ways.

Any trip into the past must always involve the possibility of dangerously altering the entire scheme of the future; several writers have posited a "damping effect"--i.e. someone goes back, kills Adolf Hitler as a boy, and yet another Hitler takes his place and becomes almost the same man in all major effects, etc.--the main timeline goes on despite small alterations for the same reason a great river would be essentially unchanged by the removal or introduction of a twig into its current.

The travel mechanism is simple--exceed the speed of light; supply enough crude power to disrupt the time continuum; contact the future men or let them find you and let their machineries do the necessary trasnport work; use the mind to contact a man or a past or future age; have yourself frozen until the future happens; exchange your mind for someone else's in a past or future age; leaving your body behind, let your mind's electronic webwork "freefare" faster than light and travel where it will; use some as-yet-unidentified magic for the journey, etc.

That's most of the possibilities list; it may be that tachyons, hyperspatial bubbles, holes through space, faster-than-light drive speed, magic, ESP or crude power will someday allow an inventor to effect a temporal exchange of mind, minds, body, material, etc. At the moment, we lack the manual and the device to make this happen.
Too bad...

Answer 4

Time travel is not possible in the simple fact that time travel would be to the past and the future and the present.
The world would be crowded in all eras with time travelers if it could be done.

Answer 5

ask me yesterday. Don`t know if really possible, but don`t think it will happen or we would probably be aware of visitors. If it is possible, I hope that we travel back to now and save us from ourselves. Now some will argue that as a clock moves that we are slowly passing into the future, I say no because, it is always NOW, no matter what you do.

Answer 6

Time travel is a physical impossibility. The reason for this lies in the limitations of the physics trilogy. Notice in E = mc2, m = E/c2, and c2 = E/m that the first two equations have as the basis of their existence the value of "c2". In the first equation the value of "c" is the multiplier and in the second the divider. In each case it is the value of "c" that is the basis of the equation. In the third equation the "c2" value is that of a relationship between mass and energy and is itself (c2) a field of gravity or that of physical time.

Because the basis of our existence is that of "c2", this value describes our existence in relation to the past and future. There is no such thing as a past and future to us. All that exists is present time, and this value moves at the speed of light. What we perceive as being reality has already passed us by even as we recognize it, and has been replaced by present time anew. Those who have lived in the past are physically present with us now, only they have been changed into gasses and dust. Those who shall live in the future shall be composed of the present time those of the past once knew, and which we now experience.

For us to move into either the past or present is impossible for all that exists is present time whose totality is described by the very narrow, extreme duration of "c2" existence - which value we, as our universe, are composed of.

Answer 7

time travel happens right now! look at a clock and watch the second and minute and hour hands. they are all moving forward.
time travel only goes into the future. so far it is impossible to travel into the past. but, "impossible" only means now.

Answer 8

I would say it is FANTASY, because you define sci-fi as something that one day can or will come true, even though time-travel is a common theme in science-fiction. Call it fantasy for its implausibility.

Answer 9

the priority with this ideas-set is that movie makers are unfastened to invent something they prefer and don't could clarify themselves. there is one movie you could see that is what you're searching for for. that's a movie observed as "touch" according to a singular by Carl Sagan. the main character is loosely according to a actual existence SETI researcher Jill Tartar. that's as you will possibly assume from medical expert Sagan a nicely theory out tale which could provide some cloth on your project.

Answer 10

Nope. Flat Earth Society proved that time travel can happen. They just didn't have enough resources to buy Flux Capacitor. Therefore it didn't happen...!!!
