Time Traveller John Titor ...real or hoax?

[Dedalus]

If time travel was possible, wouldn't we know about it by now? Wouldn't someone have come back and told us? I mean someone besides this guy.

I suppose they could have decided in the future to enforce rules like "no travelling back beyond 2010" or something.

time travel is possible, and has been proven to be so. both mathematically, and experimentally. all they've done at cern is detect atoms/electrons that have moved from one space to another, or they seemingly 'created' atoms out of nowhere. it's similar to travelling faster than light. they've made atoms and such travel faster than light. it all ties in with string theory really. i'm not an expert, but read up on some of that stuff.

we never hear about these discoveries because there are 'more important' things worth reporting, which i won't go into since you can all get an idea where it's heading.

none of these wild ideas are being worked out how we've been led to believe in movies. there isn't some freaky haired scientist somewhere in the US with a little kid following him around with a skateboard.

dont you mean "hoverboard"?

Time travel from one timeframe to another is completely impossible - however travelling faster than light does alter the time perception of the object moving at that speed, meaning by the time it returns to its origins, it can have experienced much more or much less time than that of its origin - but it is in the same timeframe.

This is what scientists are on about when they mention time travel at speeds exceeding light.

Time travel from one timeframe to another is completely impossible - however travelling faster than light does alter the time perception of the object moving at that speed, meaning by the time it returns to its origins, it can have experienced much more or much less time than that of its origin - but it is in the same timeframe.

Damn...so I can't go back a a few hundred years and steal gold with weapons from 2034?

 

[lePobz]

No, if anything like this were possible then no timeline would be constant. Even one person going back in time could theoretically corrupt the timeline enough to ensure that the timeframe he/she didnt exist or the time-travel technology was never invented - creating a causality loop which just doesn't happen. Proof enough timeframe to timeframe travel is a complete impossibility, regardless of how many thousand years your civilization spends trying.

EXACTLY! Time travel simply is not possible (IMO). Time is just our perception of change (IMO) - there is no 'thing', no 'variable' called time that can be manipulated or changed. I can understand travelling at the speed of light changing the behaviour of elections/atoms etc so they effectively move slower, and you experience time slower, but this is just an illusion, a side-effect. Time isn't changing.

I got up at 8am, I travelled forward in time to 6pm were I had dinner. Time travel occured. They put an atomic clock on a satalite circling the earth that start off perfectly in sync with another clock on the ground. When they recoveded the satalite the clocks were slightly out of sync. That's not an illusion. Going into the theory of realtiliy gets even more complicated.

Now the argument point is about if its possible to reverse time is a good one, and I agree if it was possible to go backwards in time, someone would of done it and come back to tell us already.

sorry bout spelling, half watching Liverpool play, half watching my CZ team play.

If you're talking about time dilation, I'm pretty sure that doesn't allow for FTL travel. The equation used for acceleration is Force=accelerationXmass but as an object approaches relativistic speeds its mass increases, so at c your mass would be infinite, thus requiring an infinite ammount of energy to accelerate yourself to that point (c is the speed of light btw).

As far as I know there is no way to travel faster than light, but you can travel far distances (let's just say 1000 light-years) in a short ammount of time (let's say 1 hour). Just due to time-dilation, while the trip was only an hour for you, expect all your friends and family to be long dead, 'cuz thousands of years will have passed for them.

Also, as far as I know travelling back in time is completely impossible, however I do remember one proposed way to make a time machine, which could send you back no further than when the time machine was built. It involved exotic energy and a stable wormhole, with one end near a neutron star. I don't remember the specifics, but I'm pretty sure it was impossible too.

This is more of a discussion for physicists. If this guy wanted to prove to people that he could travel through time, he could easily prove it, as well as win a Noble Prize and probably the JREF also (that would get him 2,000,000$ I think)

Actually travelling back in time is not impossible. I was watching the discovery channel and even now some scienctists ate building machines that will allow you to do exactly that. I dont remeber how the machine works but it was something like they shoot a laser up in a spiraling motion at a speed faster then light theoretically allowing things to travel back in time (i dont rember if it was forward also). But the scienctist said once he gets the machine working someone from the future can send an object back in time and it will not effect the future. The grandfather paradox if anyone has heard about it. You cant go back in time and shoot your own granfather becasue then you would never have been born to shoot him. The gun would misfire or something but the point is he wouldnt die because it would affect you. (Theres two granfather paradox's one where killing him will effect the future and another where it wont) I have to watch the show again because I know im missing a lot of information but that is generally what they mentioned. Another thing they mentioned was you can only travel back in time as long as the machine was on. So if you turned the machine on in january 1 2003 and the date is now january 1 2004 you would only be able to travel back to january 1 2003 and not and time befor that. I dont know if that makes sense but that is what was metioned in the show.

 

[h4vvok]

I fully believe time travel is possible, as scientists nowadays have proven nothing is impossible, just improbable. I wouldnt throw any theories out the window until they can be tested

 

[Tr0n]

I want a pony!!!!Sorry farrow...had to.

Also I for one don't believe time travel is all that possible...but what do I know?I'm just a stupid redneck.It just seems impossible to go back in time....

 

[Dedalus]

when you think of time you need to stop thinking about that face with the hands and the ticking and the rest of it. throw it out the window, because that's extinct, and has been for almost a hundred years.

so we've established there's no such thing as time. the universe does not have a wristwatch. yes we log our events in space by using a clock, but it's a poor way to measure it. and when i say 'it', i'm not completely sure what i'm referring to (because i'm not a bloody scientist alright?!). best thing would be to read up on quantum mechanics and String Theory.

it's very confusing and seems like it's all made up. but it isn't. it's all been proven mathematically, and like i said above, prove experimentally. anyone who reads New Scientist will know what i'm on about.

but basically, don't think of time as following a timeline, and when you think of time don't think of a clock. it's hard to explain so just get reading alright!

 

[Farrowlesparrow]

When scanning over the title of this thread...it really looks very much like it reads as "Time travelling John Travolta...Real or Hoax"

 

[CptStern]

here's an anology that might make it clear:

if you had a telescope pointing at a planet 1 light year away and you were able to instantly transport there, would your assistant (who's looking through the telescope to where you're supposed to materialize), see you arrive on that planet?

answer: no, if he came back a year from now he would be able to see you arrive because the image would take a year to reach the telescope

 

[Raxxman]

yeah but:

If Object A is stationary, and Object B is traveling towards object A at the speed of light, the speed of approach is the speed of light.

Simple.

However if Object A is stationary, and Object B is traveling towards Object A at the speed of light, and Object C is travelling towards object A from the opposite direction at the speed of light. How fast is Object A approaching Object C?

Answer is the speed of light.

Confused yet?

BTW theoretically there are particles known as tachyons, which travel backwards through time, its how they travel faster than the speed of light which is the theoretical limit. But yeah, time is anything but constant, as is the peception of time.

 

[Ghost Freeman]

We've discussed this enough, no?

 

[Voodoo_Chile]

I'll just add what I can.Apparantly scientist have time machine designs formulated and the theories behind them fit the Math,HOWEVER(Important that) the componants for one of them involves creating 3-4 blackholes and harnessing them in some way to do something to space.(Its been awhile since I saw the program and the specifics are lost in my mind)
Another involves a Galaxy wide sling shot device,again Ive forgotten the specifics.

The only theoretically possible way to see the past would be a Highly adaptive computer program which is populated by sentient AI's with personalities which have been programed for the timeline.The theory is that the computing power of 100 years in the future could run billions of these worlds simultaniously and see how they lived and so forth.

[nw909]

Even if John Titor is real or fake, I don't like him.

end of story, guys.

There was a stint with a GIf animater awhile back.Must change it.

 

[Sparta]

dont you mean "hoverboard"?

apparently those hoverboards are real. Or so i've been led to believe.

Those two black disks on the bottom of the board are two of the same magnets (When i say same, i mean Negative and Negative or Positive and Positive) that push each other way, allowing the board to hover.

Well my sister's boyfriend says that its on the BTTF Special Edition DVD as an extra but i'm not sure if he's telling the truth or what.

Edit: looked it up on the internet, nope they used wires
http://www.jhallman.com/bttfprops/part_2_hoverboards.htm

 

[Raxxman]

Magnets wouldn't work, as all the board would do is flip over and stick to the floor.

 

[Wiseman]

The last I checked (http://en.wikipedia.org/wiki/Tachyon), a tachyon is a hypothetical particle, not a theoretical one, so appealing to tachyons isn't convincing.

Actually travelling back in time is not impossible. I was watching the discovery channel and even now some scienctists ate building machines that will allow you to do exactly that. I dont remeber how the machine works but it was something like they shoot a laser up in a spiraling motion at a speed faster then light theoretically allowing things to travel back in time (i dont rember if it was forward also).

I dont know if that makes sense but that is what was metioned in the show.

What's the point of going back in time if you can't do anything that'll affect the future. You can't stop/warn people of distasters, you couldn't leave a rock on the beach (that would affect the future, however pointlessly). You could go back to watch stuff I suppose (for historical purposes) but if you couldn't go back past when the machine was built, it'd be very expensive to build and pretty useless. Law enforcement would have the best use of it. Wait, I just counter-argued my own argument. Nevermind.

However if Object A is stationary, and Object B is traveling towards Object A at the speed of light, and Object C is travelling towards object A from the opposite direction at the speed of light. How fast is Object A approaching Object C?

Answer is the speed of light.

Do you mean, "How fast is Object B approaching Object C?" You already said that C is travelly towards A at the speed of light, so unless you made a typo, you're just repeating yourself. My point is however, that that isn't related to time travel. That's just part of special relativity I believe.

I fully believe time travel is possible, as scientists nowadays have proven nothing is impossible, just improbable. I wouldnt throw any theories out the window until they can be tested

Some things are impossible. It's just impossible to determine what is impossible. We can find data to suggest something is impossible, but we could've been hallucinating the data, and any evidence we find which suggests we aren't hallucinating could be part of the hallucination. But for practical purposes, we assume the data is more or less accurate (and I don't want to get into a debate about solipsism, 'cuz that's offtopic (as well as kind of stupid and meaningless)). The only thing I can be sure of is I exist, but I don't care if others exist or not; I'll just assume they do.

 

[Raxxman]

yeah sorry about the typo, B and C, point is relativity and time are related.

And as for tacyhons being hyperthetical, last I read in scientific america there is a lot of work going on into tacyhon research. Tacyhons also feature heavily in string theories.

 

[Wiseman]

Well I can only use the internet as my source of info (I don't get scientific america or discover ) so some stuff is often out-of-date (although wikipedia is usually up-to-date). From the definition of tachyon in the beginning of that wikipedia article "A tachyon (from the Greek ταχύς {takhús}, meaning "swift") is a hypothetical particle that travels at superluminal velocity.", compared to the definition they give when referring to string theory "In quantum field theory, a tachyon is a quantum of a field - usually a scalar field - whose squared mass is negative." They seem to be almost different things. I also know there're problems with string theory (http://en.wikipedia.org/wiki/String_theory), so it could be false, but since I really have done very little research into string theory, I generally just like to not discuss it.

Honestly I should probably just back out of this discussion right now, since I'm not very up-to-date with this stuff.
