Time Travellers are real? or were in 1928...

[zfactor]

Time travel is impossible which means this is a fake. End of story. That was easy.

How do you know what can happen in the future? hell people though Mobile phones would fail, we never though that we could travel in something with wheels witch ran on something called petrol. Hell we never though we would make something that can get into space...

But ooh look!

Well, if time travel will be possible in the future; how come the holocaust happened?

Ah shitpickles... This thread got way off topic...

I explained in another thread actually about time travel about this... You cannot change what has already happened. The past is written and unchangeable because of the fact that it already happened. So if ou go back and try to change something, you will fail because you already failed. You already went back to change whatever happened.

Confusing as fuck? Yes...

I'll explain better. Let's say you wanted to go back in time and try to stop Hitler. The events of 1945ish have already occured, yes? Therefore, you cannot change anything because it has happened already. In 1945 you were there trying to stop Hitler already when everything still happened.

Still confused? Quote me and I will try again...

COuld be a very small walkie talkie type thing.

True...but you don't hold Walkie Talkies to your ear...

And during that time period they were pretty massive. If they even existed.

Did anyone see a Police Box or DeLorean in the video anywhere? (or maybe a modern phone booth?)

Time travel is theoretically possible. (I explained it in another thread in more detail...)

Approaching the speed of light causes time to slow down (x EvilErmine x is right) and exceeding it would reverse time to keep c constant for you. THERE IS NO NEED TO RECREATE THE UNIVERSE. Because if you reverse time (-t) every reaction, speed, acceleration, force (every vector or equation involving t) reverses itself, thereby reverting the universe to a previous state. Time "jumping" (going directly from 2010 to 1928) is impossible, you have to reverse t and go through all the years in between. Time reversing is possible, we just haven't found any way of going faster than light.

Oh and mass doesn't distort time, it distorts space, which distorts time. (mass bends the fabric of space, which condenses (slows down) time).

But wouldn't that still just destroy everything in the universe basically?

No. Where did you get that idea?

Putting negative t into an equation would reverse it, not destroy everything. If you went too far back (to the big bang) then yeah the universe would get destroyed, only according to you. Time would be reversed for you. You would see everything revert backwards, everybody else would keep going normally.

I can't wrap my mind around that. How would time reverse itself for you but not affect anyone else?

You are the one causing the time travel, causing your observations of t to be negative. The universe as you see it would reverse, not the universe as everyone sees it.

Maybe it was given to her by one marty mcfly...

Maybe she saw the camera and got all embarassed, and tried to cover her face?

 

[Irony's Acolyte]

I didn't see any phone in her hand. In fact I couldn't see anything in her hand. You people probably just say her holding her hand in a way that now-a-days would be associated with talking on your cell phone, when really she was just scratching her head or something like that. No need to get all paranoid over it.

This, but then if you consider the possibility of alternate parallel dimensions then it becomes possible in a way.

 

[zfactor]

Time travel to the future is possible though, all you need to do (ha that makes it sound easy lol) is get close to the speed of c (this makes time slow down to preserve the absolute speed of light) or get close to a really massive body such as a Super Massive Black Hole (this is because mass distorts space time as can be proved by the network of GPS satellites).

Interesting. I actually didn't know this. So by getting close to the speed of light time would slow down around you but go at the same speed everywhere else? I guess that would be possible once we actually discover a way to get close to the speed of light. Still, the super massive black hole theory is a little impossible, isn't it? I mean, you'd have to find a way so as not to get sucked into the black hole since if I remember correctly at a certain distance not even light can escape.

You recall correctly, that distance is called Schwarzschild radius. It's the distance at which if you get any closer the gravitational pull would become so strong that there is no force in the known universe that could stop you falling in toward the center. Stay above this distance though and provided you could keep up the velocity to prevent orbital decay then you are golden and will begin to travel through time for the reasons that zfactor stated. (my he's right and i misused the concept of space time)

@ zfactor while what you say is true i don't think you could exceed the speed of c in normal space as far as i am aware. The closer you get to c then the grater the mass of the object becomes up to the point where at very close to the speed of c your mass effectively becomes infinite thus requiring more energy than is contained in the universe to accelerate you further. Please correct me if I'm wrong here, this type of stuff interests me

I don't think approaching c would cause a mass increase... But if you could exceed it (which is what this thread is about) t would reverse.

Yet, space itself can travel faster than light (according to an outside observer). This is because it may be impossible to travel faster than light locally (velocity = c), it is possible to make space velocity > c. (Your local v would be 0, the space you are in would move really fast, but seem to be still...) This is the priciple of the warp drive (yes, Star Trek) and the reason nobody is effected by inertia (if you jumped to lightspeed, wouldn't you get flung bakcwards?)

But blargh, I've got a class to get to soon...

Because that is a rather sizable and significant event. Changing that would have changed HUGE amounts of history, which could create an unbelievable paradox which might wipe you out so that you couldn't change history so....

Being able to get back in time doesn't mean you could...or should...mess with the timeline in any significant way.

That wasn't my point though. I was just pointing out the Stephen Hawking argument with a tiny twist. If time travel is possible, why haven't we been flooded with time travellers trying to stop the major catastrophes in history?

I just attempted to point out that travelling back in time would create huge paradoxes like that. Unless of course we assume that timelines can branch off, but then we wouldn't be able to see the lady with the cellphone in this timeline in any case.

OT: I'm going with the hearing aid.

 

[Koeryn]

Considering the fact that you can see THROUGH the person? Sure. Time Traveler. No other possible explanation.

That or gasp! It could be a GHOST! Seeing as you can see through them. So they're a time traveling ghost, who talks into wallets.

Hot damn, I think we have a new series. Quick, someone get some animators so we pitch a pilot to Adult Swim!

This, but then if you consider the possibility of alternate parallel dimensions then it becomes possible in a way.

Creating a parallel dimension requires time to be two dimensional (how can you get there otherwise? You have to make a "bridge" on the timeline joining them somewhere, if time reversal causes alternate dimensions). Since time is one dimensional (forward an backward), I don't think alternalte universes are formed by time reversal/travel.

 

[JourneyThroughHell]

Erm, soo, who is she talking to then? Are there comm towers and sattelites in 192whateverthehell?

Maybe her ear is hurt. Maybe she is fixing hair. Were she a time-traveller, would she walk down the fucking road with a mobile phone speaking to someone during the time where no one has seen anything like that ever?

Lies, I say. Lies!!!

Timetravel is about as possible as religion.

Actually nothing is impossible.

I am going to sound completely stupid here...

But how do you know no one has tried to stop these events. Because surely if someone tried, and said "I'm from the future, and have come to stop [insert major event in history here]" then he would be sent to mental hospital (or killed if it was ages ago)

In order to travel back in time you'd have to find a way to re-assemble all the atoms in the universe so as to remake the world before. This would mean you'd have to basically re-assemble the universe. This is impossible and besides that, if you DID actually do this then you'd kill everyone in the universe.

There is a "WAY" to travel back in time by means of traveling faster than light in such a way that you'd reach a point where the light coming from earth would be the light that left earth about a few thousand years ago. It would be looking in the past but not traveling back.

I know you're going to say the same thing you did now. "You can't know what happens in the future" and that's true, I can't know what will happen. However, I can state that manipulating the universe at such a grand scale is impossible, as you'd have to manually reassemble every single atom so as to re-create what happened before and that is, again, impossible. Even if we wind a way to manipulate atoms in such a way so as to create the past you'd still have to take in account the task of actually manipulating them into place. Do you know how small atoms are? Do you know how long it would take to actually recreate the past? Do you know how much it would take to recreate the entire universe in the past? And if you don't want to do that then you'd pretty much have to create a separate universe to house your old earth and then you'd have to artificially create atoms and then put them into place so as to recreate the earth. But then you'd have inconsistencies because all we have for information about the past are old texts so you can't really be sure what person A from China was doing during say the Medieval era.

There are to many variables to be taken into account in order to make "time travel" possible. In the traditional sense it's impossible and even in a modern sense it starts to look impossible.

No it isn't. There's nothing in the laws of physics that prevents it. The vid is not of a time traveler though as you cant go back to a point before the time machine was invented, this would create a paradox and also would violate the law of thermodynamics.

Time travel to the future is possible though, all you need to do (ha that makes it sound easy lol) is get close to the speed of c (this makes time slow down to preserve the absolute speed of light) or get close to a really massive body such as a Super Massive Black Hole (this is because mass distorts space time as can be proved by the network of GPS satellites).

Time "jumping" (going directly from 2010 to 1928) is impossible, you have to reverse t and go through all the years in between. Time reversing is possible, we just haven't found any way of going faster than light.

Oh and mass doesn't distort time, it distorts space, which distorts time. (mass bends the fabric of space, which condenses (slows down) time).

first off, time dilation is not time travel. you dilate time by increasing the speed of mass, but that by no means is an example of 'time travel' as you are not 'skipping time' but rather entering a form of stasis which envelopes your preception of time.

Time travel for all intents and purpouses is purely impossible because it breaks the fundimental laws of physics. its very existance in any other time frame besides its own is a paradox in its own right.

imagine taking a Nail and sending it back in time... hell, 2 minutes.
in that simple process you've duplicated Matter.
you've broken the law of conservation of Matter.

even if you want to throw in theoretics, quantem dynamics, or expanded relitivity, time travel is simply impossible.

the universe is a closed system, the arrangement of mass and matter as you saw 20 years ago has been used to make the arrangment of mass you see today. unless if you plan to rearrange the atomic structure of everything in the universe time travel is impossible.(oddly enough, see the parody film 'Galaxy Quest' is some what spot on with this)

Yeah, timelines don't branch off (see above post...), and I was saying it is impossible to change anything because of the linearity of time. What happend happened, you were already there to try to stop it and failed because it happened.

A strange theory, I know. But it's off to class, so you will have to be confused on you own.

Yes, but just as Mr. T has the greatest hair in the world. Science has proven that time travel is impossible, at least backwords. Now foreward is another story, but then you'd be trapped in the future.
