Do you think time travel is possible? if it is why hasn't some one come back in time to our present from the f

Question

One would think if time travel is possable one would have come back from the future by now. Or has mankind killed him self off befor time travel was discovered?

Answer 1

We've been shown in the fields of physics and quantum physics that space itself isn't as simple "point A to point B to point C." Space bends and curves and twists.

Why would time be any different? This is largely theory, but time has been called a "stream." Like a stream, it's easy to see a time stream of eddies, branches, undercurrents, back currents, and still pools. It's possible for water craft to go against the currents and travel upstream.

So I fully believe it's possible. Just because it's possible, or it's been done in some future time, doesn't mean everybody would do it. For most people, time travel wouldn't make a difference in their lives, so they wouldn't take that plunge, just like today, we can travel the world, but most people never will.

Also, because a time traveller comes back from some future date, doesn't mean it will be of record. We'd have to interview every person on the planet to find someone who's met a traveler. Even then that person might lie to keep the secret, and the traveler, safe. If you accept life on other planets (I do), then it's possible that such a traveler might have done it on another planet, not ours, and that person probably would not go back in time to another planet (would you?), but his own.

So we'd have to interview the people on every planet to find that out, and then the same problem applies.

But I feel that it's fully possible, and that God made the universe fully capable of reorganizing itself to handle a simple thing like paradox.

Answer 2

Yes I believe it is possible, but I also think there may be some forms of universal law which might restrict ones movements and actions in these different time zones. Maybe you are aloud to travel in time, but not interact with it, because you could then inadvertently change the past, present and future as well !

Answer 3

There are time travelers who came to the present from the future. No one believed that there are time travelers from the future. They think that the time traveler is lying. Sometimes Time Travelers make mistakes about future events.

Answer 4

it really is something maximum do not evaluate. allow's say you dial again a Time gadget a million Planck time (5.39x10^^-40 4 sec). What then? might want to there be 2 of you occupying an identical area? might want to you unexpectedly weigh two times as a lot, have 4 eyes, 4 legs, 4 hands, ... etc. might want to it violate the Pauli exclusion concept (no 2 same fermions might want to occupy an identical quantum state concurrently)? it really is yet another using the wormhole theory. You stand on the part then strengthen some arbitrary ?d, say 0.5 cm. the position are you, or maybe as? once you commence to enter the wormhole, area of your body is in st1 (area-time area), and area in st2. perchance i'm lacking something uncomplicated, yet i will't see a fashion round this, no count number how this is finished, wormhole, time gadget, multiverse, in spite of. same is going for teleportation. in case you ascribe to the Multi-Worlds idea, as you pass flitting about doing st-to-st transitions, are you a unique you after each transition? And, if so, are you an identical you yet different, or a unique you in spite of the undeniable fact that an identical? after all, in a unmarried way or yet another, you're reconstituted for the period of each transition. Do you free that which makes you uniquely you? For time commute to artwork, might want to it necessitate the prompt move of the eigenstates of all the quantum factors to the selected time? To do otherwise, might want to one's count number be smeared out backwards for the time of time?

Answer 5

Assuming it is possible...how would you know if someone DID come back from the future? If such a thing were possible you can bet your existance (Literally) that the foremost rule would be to NEVER reveal yourself as a time traveler because then that knowledge could end up changing the future.

Answer 6

Another figment of science fiction. It is not within man's reach to time travel or even teleportation. A FAX is not teleportation. The best anyone could hope for is to discover the powers Nostradamus was blessed with.

Answer 7

May be it will be possible one day, but they don't travel intop the past by their law, because each event in the past caused by their possible presence would have cascades of consequences in their future ... so, if they are intelligent, they would never ever travel into their past.
However, we don't know, maybe they can and their technology is that advanced they can disguise themselves completely and "visit" us as observers only, kind of studying their own history. Who knows ..

Answer 8

I've included two answers that I have submitted to other questions. The first one essentially defines Paradox, while the second one relates to Einsteins special theory.
The key premise to remember regarding paradox, is that mathematical truth contradicts naive intuition. In the twin paradox, naive intuition would tell us that time would be the same across reference frames despite what acceleration might be involved. Einstein's mathematical truth contradicts this naive intuition. I hope this helps.

Yes, check out the birthday paradox on wikepedia. In essence,
this paradox demonstrates that mathematical truth contradicts naive intuition.
The problem: If 23 people are randomly selected it is about a 50- 50 probability that at least 2 will have the same birthday. Most people when confronted with this problem will intuitively estimate that selecting only 23 people will be considerably less than a 50-50 chance of having at least 2 people with the same birthday.
They will also estimate that to get to a 50/50 probability it will have to be considerably more than 23.
At wikepedia they give several different mathematical approaches to solve this problem. The best and simplest is;

A simple exponentiation
P(n)= 1-(364/365) ^(nC2)=
1-(364/365)^(23C2)=
1- (.99726) ^ (253)=
1- (.499488)=
.500511872

(nC2) is also expressed as n Choose 2...This is a factorial.
Therefore (23Choose 2) gives you 253 possible combinations.
(23x22/2x1)=253 This will be the exponent for (364/365).

With 60 people randomly chosen, this exceeds 99% chance of getting at least 2 with the same birthday.
P(n) =1- (364/365)^(60C2)=
1-(.997260274)^(1770)=
1-.00778178=.99221822

In essence, some Paradoxes can be proven false, as this one has been demonstrated. Some of our false truths throughout history have been based on naive intuition and only resolved with counter intuitive approaches. I hope this helps! GL



Below is an answer I submitted to the question "Is time travel possible"? In addition to this, Time, Size, and Mass will all seem normal for those in their own reference frame. These entities would seem peculiar, for example, if earthlings could somehow see (see in another reference frame outside their own) the people traveling close to the speed of light. The Earthlings would see the travelers shrink, become more massive, and notice that their clocks were running significantly slower. The following is a a brief description of time , the 4th dimension. I hope this helps.

Yes, one aspect of time travel is theoretically possible. That is to say, according to Einstein's Special theory of relativity it is possible to travel into the future. How far in the future in a given time span depends how close to the speed of light you accelerate. Traveling at 80% of the speed of light according to Einstein's formula y=1/ Sqrt 1-v^2/c^2 ,(v=velocity, c= speed of light) the clocks on Earth will advance 1.667 times faster than the one traveling in space. Therefore, after a twenty year journey by the space travelers, (20 yrs time has elapsed by the travelers account) upon their return, there will have passed on earth 33.4 years.
At 98% of the speed of light, 20 years of travel at this speed, upon return, 100.4 years will have passed on earth.
This is the equivalent to traveling into the future, which is a form of time travel. Therefore time travel is theoretically possible. In fact, check out this site as the guy proclaims that we will be able to approach speed of light travel within 100 yrs.
http://www.physorg.com/news10789.html......
Traveling back in time is debatable, as you would have to be able to exceed the speed of light to do that.
Plug in the numbers to this formula. speed of light c= 186,000 miles per second. For velocity, just multiply this number from .01 to .9999. Then just follow mathematical operations.
good luck

Answer 9

Time travel is possible why do u think george w bush is such a
tyrant & sends young boys & girls to slaughter defenceless old people,disabiled & children ??
He went back in time & got lessons from pol pot.
America should wakeup to what he is doing so big industry to profit from the death of the young.
I think if george w bush was assasinated no one would miss him
& the assasin would get a medal from the world.

Answer 10

First it is not possible.
You actually answered your own question.
If time travel were possible,time machines would blossom out into every era,they would be more common than cars.
I would have one and I would have been all over the joint!
