Pfft, isn't it obvious? That's the Terminator, in disguise as an old woman, going back in time to kill Sarah Connor's parents, before she can be born. That "cell phone" is actually a futuristic pager to tell his fellow machines that his work is complete. Geez, k'shaw, you guys can be such dolts sometimes

Actually, time travel is possible. It's one-way, though, so it's only possible to go to the future (as far as we know).

I am in no way responsible for you getting stuck in the future if you decide to time travel.

Well, if we want to get really technical WE'RE TRAVELLING THROUGH TIME RIGHT NOW.

And it looks like we're stuck in the present. How boring.

True, but that's not what I meant. Mass causes distortions in the space-time continuum, AKA gravity. If you went somewhere that had an enormous amount of gravitational pull (like next to a black hole, for example), time would move faster due to this distortion. If you came back to Earth, more time would have passed than if you never left.

Also, I doubt mankind will ever be able to travel backward in time because if we ever will, then we would have people traveling back to our time telling us about it. There's the time paradox to think about, too.

Yeah, I'm familiar with the theory. Hoever, again for all real intents and purposes, time travel is impossible.

If you get close enough to a black hole to have a meaningful effect on your perception of time as opposed to the people back on earth, then jumping forward in time is the least of your problems.

Not to mention the existence of black holes haven't been confirmed (there is only "indirect evidence"), nor have there been practical experiments which demonstrate the warping of space-time at such an extreme level.

If what you're talking about counts as time travel, then walking to your local grocery and back is time travel just like flying to a black hole and back is time travel, just at different perceived rates.

Since I'm the closest thing to a detective this website will get, I'm gonna have to figure this out for myself!

First off, the actual object the person is holding appears to be held in a way which gives itself more to a large deck of cards instead of a cell phone. Second, there appears to be a shining/silver circle where the man's ear should be, leading me to believe the object isn't a phone because of the odd large-deck-of-cards-into-silver-earpiece-ish design. Third, it would be useless to try a cell phone in the 1920s, since phone towers didn't exist. Oh, and calling people in the future would be pretty much impossible since reality states that the future doesn't exist in any sort of time period at all.

EDIT: Of course, I'm not counting in things such as black holes and other cosmic forces, but I'm thinking more logically, as in based-on-now mentality.

@ rift there are people from the future telling us, but we just call them crazies

Black Holes are much like Darwin's Evolution - while no one can 100 per cent certifiably prove it happens, the 99 per cent liklihood means it's the safer bet than denying its existence.

For the rest of it, though, I agree. Technically we age slower as we fly overseas because of the lessened gravity involved with being on an aircraft - but that hardly means we've gone "back" in time.

Actually, that is wrong. From an observer far away from the Earth, a clock close to the Earth would appear to run slower. To an observer close to the Earth with the clock, time would be moving normal speed. It is called gravitational time dilation and works the same way as your normal time dilation due to moving objects. As you get closer to that blackhole, someone viewing froma very long way away would see that time was running slower for you. If you were to go beyond a blackhole's event horizon, time would appear to stop for you from and outside observer (assuming the light could travel back out from the event horizon, which it can't). A blackhole will not make you go back in time, and you will not get back out if you go beyond it's event horizon.

To those who say time is just a word we use for a measure created by humans, and not an actual phenomenon, you're wrong. This is what Einstein's theory of relativity was all about. It basically means that the faster you go, the slower time will pass, thus theoratically allowing time travel.

They actually once tried this. Scientists took two of the most precise clocks in existence. One of them was put on a supersonic airplane flying at high speed, while the other was left on the ground. Both were turned on and off at the exact same time. After reading the results, there was a difference of less than a billionth of a second between the two clocks in the measured time.

It's obviously fake. Zebras didn't exist in 1928.

I don't know about time travel, but I took a monster hit from a bong once and stopped time completely.

Time travel is only possible three ways

  • a one way trip to the future
    a police box
  • or a tacky car from the 80's

But isn't time travel a one way to the future thing. Also even if you could go back in time you couldn't change anything or do anything like stoping people from dying or taking over the world as you would cease to exist and create a paradox.

WAT!

Time Travel is possible, it just requires a few well timed moves.

...which was presumably measured with the third-most precise clock in existence.

I'm not doubting that time is something greater than a convenient method for understanding causality, but in that example as provided, the result is far from "evidence" of anything.

For one, the mechanisms of the clocks. Clocks are machines...an assortment of interlaced and codependent mechanisms that all require each other to work correctly. By changing the conditions under which they operate (as you are by putting one on the ground and one in a supersonic plane--a moving one--, which means that temperature, altitude, velocity and various other conditions are totally different and therefore not comparable at all) you assure that any discrepancy between the final two readings can, potentially, be the result of too many other factors for it to be of any use.

Secondly, there's the human error. If you ask two people to turn the clocks on and off at exactly the same time...well...it won't happen. It's impossible. Human reflex isn't nearly that precise.

Thirdly, you cite a difference of "less than a billionth of a second between the two." Which is...um...not really indicative of anything? It's definitely within the margin of error.

Without knowing what experiment you're referring to (you may not even know) I can't say for sure that it's flawed. But as you've described it, I might as well prove the reality of Time by throwing one alarm clock into my toilet, and putting the other in the microwave.

Hmm... interesting. This is probably just faking, but if not and that is truly a cell phone, then that is information proving that the invention of time travels will happen.

The position of the cell phone looks to have something sticking out, like it was from the 1990s. But how the hypothetical cell phone was used will remain a history.
