How do you get your head around time travel?

Question

Do you believe that we could go back in time, if it has already happened won't there just be nothing there, I can never get my head around time travel films where they go back in time to save someone wont they have to keep doing that for all eternity, loop it if you like. What are your views on time travel, I have heard that we are getting closer to achieving it.

Answer 1

I get my head around it by accepting the fact that time travel is a great plot device (as in fiction) and nothing else.

Actual time travel will NEVER be possible. Frankly, the only people who really think it will be are rather ignorant of science and seem to get their information from science fiction or from the crap they show on so-called documentary channels.

Answer 2

They are just Hollywood fantasies for Sci-Fi movies- there is no such thing as going back in time as shown in movies. It cannot be done.

However, as we approach the speed of light - say up to 99% we base our equations on 'special relativity'
I cannot possibly begin to try to explain that theory here, but suffice to say that under certain conditions, the perspective of time does alter.

For a detailed explanation on how time travel (as such) can be achieved see the below link.

These findings are clearly only theoretical as our current technology does not allow us to travel at such speeds and so therefore these experiments cannot be actually proven by a human traveling vai the concept.

Answer 3

noPresentism (philosophy of time)
Presentism holds that neither the future nor the past exist—that the only things that exist are present things, and there are no non-present objects. Some have taken presentism to indicate that time travel is impossible for there is no future or past to travel to; however, recently some presentists have argued that although past and future objects do not exist, there can still be definite truths about past and future events, and that it is possible that a future truth about the time traveler deciding to return to the present date could explain the time traveler's actual presence in the present.[11] This view is contested by another contemporary advocate of presentism, Craig Bourne, in his recent book 'A Future for Presentism', although for substantially different (and more complex) reasons. In any case, the relativity of simultaneity in modern physics is generally understood to cast serious doubt on presentism and to favor the view known as four dimensionalism (closely related to the idea of block time) in which past, present and future events all coexist in a single spacetime
i don't think that time travel is ever possible in real life.

Answer 4

In theory, you can travel back in time. It is possible. There is this matter that is almost as small as atoms. It is called quantam foam. This "foam" is actually trillions and quadrillions of wormholes occuring in trillionths of a second. You can make these wormholes bigger by threading some exotic fiber and making it grow bigger.

Here is the catch, the amount of energy it would take to make something that small, that big, is possible greating than the force of a black hole. Plus, you have to spin it to the negative. With today's technology, it is impossible to preform such a feat. Actually, it may never be possible. But it is a theory, after all.

Hope I helped.

Answer 5

How do we know that in the future we did achieve it and some of the UFO sightings and such are from another time period crossing into ours on their way to say another time period.

Maybe that could explain deja vu experiences where you just know this happened before.

When I do think about it, it gives me a headache, would you remember, could you change anything, would you just be a viewer, could you show yourself to your real self in that time period and so on....

It frightens me a bit too the whole world order could be changed, if it was for the good ok, but lets face it we live in a greedy society, who haven't learned what it really means to be honest and forthcoming, and really know the meaning of "love thy neighbor as you would yourself".

We have not solved world hunger, poverty, employment for all mankind guaranteed whatever your interest and the populous need.

Proper governing of the world economy as a whole for all peoples of all color race or creed a unification of the world as one, not devided and segregated by countries or different policies, its a utopia that we have to reach and some believe only an invasion by an alien species would accomplish this, and of course more cooperation from all countries engaged in exploration of the universe. Sorry got a bit carried away there, thanks for your question.

Answer 6

time travel, is really not possible, that was proved by einstien. it is theoretically possible to view the past or the future. and if you are interested in the many problems of time travel look up the grandfather paradox.

it basically says that if go back in time, and somehow prevent your grandparents from meeting the result would be that you would have never been born. but if you were never born you couldnt go back in time to stop them from meeting. so they would meet. which means you would go back in time tos top your grandparents from meeting. is quite impossible

Answer 7

You will always hear about someone being on the verge of creating a way to travel through time. If one thing is a scientific certainty, time travel is impossible.

Answer 8

Time travel is an illogical notion that is not possible in real life; the past and the future are abstractions and are not destinations you can travel to.

You cannot go to the past because the past no longer exists.

You cannot go to the future because the future does not yet exist.

So sorry; time travel is for sci-fi only.

Answer 9

The problem is, there are lots of hypotheses as to the possibilities, methods, and effects of time travel. Choosing one as the correct method would be nearly impossible.

I will, however, say that time machines HAVE been created. Problem is, they have very limited capability, the destination time is innaccurate, and... oh, that's right, they're only large enough to transport a select few atomic particles.

Answer 10

I don't. Time travel can only occur over idiotically short periods. Like going a nanosecond back. I take Artemis Fowl's advice when dealing with the sci-fi stuff. "He abandoned his conjectures, knowing that the situation would drive him insane". Or something like that.

Now, excuse me, while I go replace my father.
