This Just In - Physicists Prove That Time Travel Is Impossible

Hi,

So basically it is also impositble to travel from one end of the solar sytem to the other. Simply because it simply takes forever with light speed as well.

I think the only way to transfer beween star systems is with some kind of thought speed. - Lightspeed X(only limeted by how fast the operator can think) type of speed. Or du da du da deee time travel

Thanks,

And what of Bell's Theorem, which suggests that there is no such thing as time..?

if time travel were possible you could undo communism and the chinese dont play that game

Maybe they are here but they don't interact with us as not able disrupt the space time continuum. Jeez haven't you seen back to the future?

There's one truth about science that's been constant throughout history and that is that science is ever evolving. To say time travel is impossible is naive because we are basing it off the principles of science we understand today.

Years, decades, centuries, millennia, etc. from now those same principles may evolve or be replaced. There's one thing I learned in life and that's that nothing is impossible. There are infinite possibilities this included as one of them.

Besides who's to say we haven't found that possibility already? NASA and TPTB love to hide stuff from us all the time, especially when it pertains to science.

This proves faster than light traveling is not possible but not that time travel is impossible ...

You have to take everything that has an effect on time flow into consideration before making such claims... I am starting to assume that scientists are becomming dumber and dumber as time goes by ...


I will give you one simple example .... Dr. Michio Kaku ... if you listen to him and have a logical thinking you will laugh your ass out ...

From everything that's been said about time travel, time slows down as one nears the speed of light, and that if that speed were ever achieved, time certainly slows down even more. A minute to such a traveler would be years/decades for everyone else. By the time that traveler returns home from his journey, centuries might have passed on Earth, and for him it was just a few minutes/hours. In that sense, he has effectively time traveled into the future because he hasn't aged that much.

Next, no matter how well or poorly written article states, one cannot prove a negative. This is an axiom of science. It is tried and true because we humans simply aren't aware of everything that is out there. It is rather arrogant for someone to assume we know so much about everything that we can safely assert that time travel is impossible. Just weeks before the Wright Brothers proved that heaver-than-air flight was possible, scientists got wind of their experiments and *proved* that heavier-than-air flight was *impossible.* We see how that turned out.

While time travel may or may not be possible, it is scientifically problematic to even attempt to prove that something (anything) is "impossible."

i still prefer the stephen hawking theory that time travel is impossible because there are no tourists from the future.

Playing devil's advocate for second: Maybe they blend in with the others (or are just invisible) as to avoid influencing the timeline in any shape or form. Maybe theres some sort of laws regarding time travel when it was invented to prevent creating paradoxes or something of that nature.

tl;dr: People advanced enough to travel through time probably are advanced as to how to avoid looking they have done so.

Theoretically you can travel to the future but you can't go backwards in time travel, and this is because the closer you get to c, the slower your time elapses. Taken to the extreme, a photon traveling c experiences no time. So going toward a light source, doesn't mean you see things faster because you are approaching the source, (like a head on collision of two cars going 60 hit at 120) that's not how light constant works, you always see light travel c no matter what direction you travel towards or away from a source of light according to you.

Exactly right, I read somewhere, someone said, time travel is possible, we are traveling through it right now. (the hard part is changing direction. besides, is it not a common idea that nothing is impossible, perhaps improbable, but not impossible)

reply to post by NorEaster


And this is the problem with mainstream physics. That photons can't travel faster than the speed of light proves nothing in relation to time travel. They aren't taking into consideration that there is a whole separate reality that doesn't even involve a physical universe. This has been strongly suggested time and time again over the years through people like Bob Monroe and Thomas Campbell. Mainstream science is a lot less about true discovery and a lot more about funding, politics, and only traveling down paths they already know. It's almost as narrow minded as the christian who thinks there is a white bearded man in the clouds looking down on us hating and loving everyone at the same time.

They have proven nothing other than that photons obey the speed of light.

Not that i believe any of this is real, but for the sake of
argument in response to this Thread.

Is not Teleporttation a form of Time Travel?

Here is a news article about it.

(Excerpt)
Scientists Discover Time Teleportation

Jesus Diaz — Physicists at the University of Queensland in Australia claim to have discovered time teleportation, no flux capacitors involved: Just like quantum physics allows for teleportation in space, they say that the same is possible in time. Time travel to... the future!

Now, hold on to your plutonium-proof underpants. This doesn't mean we are going to the 24-and-a-half century driving Mr. Fusion-powered DeLoreans. Their discovery shows that entangled quantum particles can travel into the future without actually being present during the time between now and the future.

This doesn't deny the ability for one to travel into the future. It just means that you cannot make something go faster than the speed of light. Going into the past is still quite impossible to current knowledge, but gravity can be used to go into the future, and to achieve FTL speeds from the outside observer.

What this proves is what is already known. Physical matter on its own is bound by the speed of light.

NorEaster,

That is for the questions you have about time dilation, you said you needed links to a reputable sources, I used wiki but if you really want a source it was in sciencemag last year, all the way at the bottom. I was with all the way to there, what happened?

en.wikipedia.org...

Time dilation would make it possible for passengers in a fast-moving vehicle to travel further into the future while aging very little, in that their great speed slows down the rate of passage of on-board time. That is, the ship's clock (and according to relativity, any human travelling with it) shows less elapsed time than the clocks of observers on Earth. For sufficiently high speeds the effect is dramatic.

Hafele and Keating, in 1971, flew caesium atomic clocks east and west around the Earth in commercial airliners, to compare the elapsed time against that of a clock that remained at the US Naval Observatory. Two opposite effects came into play. The clocks were expected to age more quickly (show a larger elapsed time) than the reference clock, since they were in a higher (weaker) gravitational potential for most of the trip (c.f. Pound, Rebka). But also, contrastingly, the moving clocks were expected to age more slowly because of the speed of their travel. From the actual flight paths of each trip, the theory predicted that the flying clocks, compared with reference clocks at the U.S. Naval Observatory, should have lost 40+/-23 nanoseconds during the eastward trip and should have gained 275+/-21 nanoseconds during the westward trip. Relative to the atomic time scale of the U.S. Naval Observatory, the flying clocks lost 59+/-10 nanoseconds during the eastward trip and gained 273+/-7 nanosecond during the westward trip, where the errors are the corresponding standard deviations. [17] In 2005, the National Physical Laboratory in the United Kingdom reported their limited replication of this experiment.[18] The NPL experiment differed from the original in that the caesium clocks were sent on a shorter trip (London–Washington D.C. return), but the clocks were more accurate. The reported results are within 4% of the predictions of relativity.
The Global Positioning System can be considered a continuously operating experiment in both special and general relativity. The in-orbit clocks are corrected for both special and general relativistic time dilation effects as described above, so that (as observed from the Earth's surface) they run at the same rate as clocks on the surface of the Earth. In addition, but not directly time dilation related, general relativistic correction terms are built into the model of motion that the satellites broadcast to receivers — uncorrected, these effects would result in an approximately 7-metre (23 ft) oscillation in the pseudo-ranges measured by a receiver over a cycle of 12 hours.

Their discovery shows that entangled quantum particles can travel into the future without actually being present during the time between now and the future.

This is pure gibberish, the last line in the above quote, a quantam particle can travel into the future without being present in the time inbetween. How can they differentiate one quantam particle from another to be able to say this is the one that dissapeared 10 minutes ago and now it is there again. Absolute tripe.

Saying that we can travel through time is like saying we can travel through blue or green, Time is not a distance, time is a measure of periocity, time is not travelled it is experienced. One can no more travel in time than one can travel in colour or travel in sound. We can slow down the experiene of time routinely, when in an accident or such when we seem to see things in slow motion our senses are so enhanced and the frequency of our concousness so high that we perceive at a faster rate temporarily excluding most other perception of things around us except what we are faced with (accident or similar).

We can experience time while travelling or we can experience time while looking at a colour. Or we can loose track of experiencing time when "concentrating" very intently on something.

Only distanced can be traveled back and forth. Time can only be experienced one way, but it can be experienced differently. We can experience the memory of past times and guess what will happen in the future and get it correct.

Bottom line is Time is not travelled by anyone anytime. It is only experienced.

Cheers

Well, think about it, seriously...if time travel were possible, hypothetically, and we start out with say small things...atoms, protons, etc....later as we know..much much later, this would develop to bigger things...like humans. If that were the true case, if time travel was ever made to be possible, then in the extremely distant future, would they not send someone back in time? would we not see evidence of it? I mean, if seriously, time travel became possible at some point...would those researching it, studying it, testing it..not send something back to the past?

Having just had a quick think it is obvious to me that it is theoretically possible for something to traverse a distance "near instantainiously" much faster than light . The speed of light can be changed, it is not a constant.

But it is clearly not possible for something to traverse a distance any faster than instantainiously. This is an axiom. Obviously.

If something were to be able to traverse dstance faster than instantainiously that something would need to be in exsistance in both places at the same time. Which of course is not possible because something cannot come from nothing and even a duplicate of something is not the original anyway.

This is the problem with the big bang theory, if everything came from the bang then what was it that went bang, if there was nothing before the bang.

This doesn't show that time travel is impossible, only what we already knew: That c is the speed limit of the universe.

One doesn't have to go faster than light to go backwards in time.

Clocks, unlike yardsticks, are "self-referential". They simply count their own cycles.

Those cycles happen in a time reference. We know from physics that a pendulum has a period based on its effective length. It a clock changes the time measured between clicks and the pendulum effective length has not changed, then the frequency of the clock, i.e. time measured, has changed.

Same situation with atomic clocks, which use atomic cycles rather than pendulums. If the cycle changes, then it indicates that time flow has changed.

I will concede the fact that the terminology used is different between a steel rod and the tick of a clock, but the principle remains the same. The clock is measuring how fast events of a known period occur with reference to a known condition, just as a heated steel rod can be measured by a tape to determine variations in length with reference to a known condition.
