5 reasons why you can't time travel

[Job]

1:If you invented one and went back in time 10 mins there'd be two of you and ten minutes later one would get in a time machine and then there'd be three and in fact there would instantly be an infinite number of you.
2:If you went forward 10 mins and asked where you are the answer would be 'dunno mate he buggerd off in a time machine 10 mins ago'
3:Time is actually just everything moving about, the only difference between now and a million years ago is positioning.
4:To time travel you have to make a copy of yourself or as you went back in time the first thing you would do is get back out of the time machine.
5:You can't go back and kill your grandfather because even going 'back' in time is actually going forward.

*scratches head*

*blinks*

I need coffee for this one...

but if you jumped back to a time when you could catch your grandfather in plenty of time it wouldn't matter time was going forward becuase its a relative dimension to Euclidean space

Amazing, every single point is wrong.

Congratulations on being so wrong.

1. no one has invented it yet

1. no one has invented it yet

Actually, Miles Dyson and his company, SkyNet invented time travel back in the 80s

Sorry Job, gotta agree with eca here. You're utterly wrong.

1. It's noon. I jump in a time machine and jump back 1 hour. At 11 am I exit the time machine. There is now the "old" me, as in the me that just travelled back, and is 1 hour older than the "young" me. The "young" me is still preparing to get into the time machine. We both go about our business. By the time it's getting noon, the "old" me is just living on, while the "young" me jumped back, resulting in only 1 me. I have essentially just aged 2 hours in the last external 1 hour timeframe, because I have experienced the 11 am to noon interval twice.

2. No idea what you're on about.

3. Time is a dimension, just like the other three dimensions (width, depth, height). If you see it as an actual dimension (the judge is still out on that) you should be able to traverse it, just as you're able to traverse back and forth over a straight line.
We actually traverse on this line constantly, but we only have figured out to traverse in a single direction forwards, from our point of view here on earth. GPS satellites are affected by their time slowing down in respect to ours, due to relativistic issues. Learn something about relativity, Einstein and such. I can suggest "Thomas A. Moore - A traveler's Guide to Spacetime". small book that explains it rather nicely in my opinion.

4. Why?

5. Read up on temporal paradoxes. It's a classical example. You can, and you cannot. In essence, should you go out there, and kill your grandfather, you would immediately cease to exist, or rather, you wouldn't have existed at all, yet, if you hadn't existed, you wouldn't be able to kill your grandfather, so *poof* you've returned in existence.

you mean i have to turn my hoover on and jump in ?

Did any of you ever read "Strontium Dog" in 2000AD?
There was a property of time-travel that most people completely ignore or don't know about. It's all well and good to travel forwards and backwards in time, but you also need to travel in space as well.

Assume I have a time machine. I set it for 10 minutes the future and hit the switch. I am suddenly in the cold of outer space simultaneously freezing and boiling. Why?

Because in the 10 minutes that I've jumped forward, the Earth has moved on along it's orbit around the Sun. The given value for the speed of the Earth around the Sun is 29.8km/s.
29.8 * 600 secs = 17880km

So I am still exactly where I was when I hit the switch, but the Earth has moved along 17880km in the intervening 10 minutes, therefore I'm left floating in the cold vacuum of space. If you want to travel in time effectively, you need to travel in space as well... like the TARDIS does.

[edit] And if anyone was wondering, my nick is from a character in 2000AD.

 

[cHodAX]

I had a time machine once, it was made by Sekonda. It didn't always work well though, sometimes I ended up arriving 5 mins later than the time I had chosen!

 

[Dreamor]

I thought if you made a time machine, the moment you make it... you can jump back to THAT point in time? So if it was made in 1990 you cannot go back to the 1800's etc.

 

[Hawkwind]

Someone watched 'FAQ about time travel'?

 

[old.Tohtori]

Well, i believe that all time-traveling endeavors work with a few basic rules;

If someone changed the past, we wouldn't notice it. It would simply change. It wouldn't shift, get blurry and reappear or anything, it would simply be.

1; So we won't notice any changes, past or present.

If someone did travel back in time, you would be one of the mass, be considered a conspiracy theorist for predicting something, be locked up or worse yet, shot. This all accelerates regarding on how far you go.

Same goes with the future, the further you go, the more "moronic" you'll be(if humanity evolves and doesn't devolve). Travel far enough and you're a regular retard for not having astral thinking. So;

2; All time-travelers would be regarded as loonies.

Finally, the mroe you travel and change things, the more you'll run the risk to mess things up so that you'll die, your parents will die(paradox waiting to happen) or worse. The further you go into the future, the more likely it is that you'll end up on an unin habitable planet or even a blown up one. Ergo;

3: Time-traveling always f*cks things up.

In conclusion, if people are time-traveling, we won't notice it and in the end they wipe themselves out because every time-traveling scenario ends in the same conclusion; it shouldn't be done.

If however people are smart enough on how to use it, we again, won't notice a darn thing

 

[Fafnir]

I can timetravel, i just concentrate hard enough and let one rip, then i go back in time to my latest dinner, then i wake up from the coma.

 

[Cyradix]

or by time traveling you end up in alternate reality in the multiverse meaning you can't change anything in your reality.... (the act of time traveling creates the alternate reality were you end up in)

 

[Sparx]

i like the idea of i time window being invented, so rather than the ability to send a person back you just create a window to view things in the past without them being changed. Would be great for historians

 

[Fafnir]

Well we will never know for sure until its invented, might just cause the whole world to implode. Today its all speculation and theories.

 

[tris-]

you cant say his points are wrong because time travel is theoretical.
his points do assume a particular kind of universe though.

 

[Olgaline]

/nerds!

 

[Lamp]

Actually his points are utter gibberish, irrespective of whether time travel is theoretical or not. I actually thought he had tried to post some lame physics joke, or that he was drunk. The only universe his points assume is one where you don't know what you're talking about. A PROPER discussion of time travel requires intelligent discourse on time displacement within n-dimensional superstring theory. Last time I mentioned that, people lost the will to live. I think I need to find a theoretical physics forum...

 

[tris-]

exactly, so it does assume some kind of universe. even if it is one where people dont have a clue!
also lamp, if youre that intelligent and clued up then you should be able to explain your theories in a way that anyone can understand. then everyone can discuss it

 

[Huntingtons]

there is only 1 time machine

 

[Vasconcelos]

there is only 1 time machine

NOOOOOO There is at least another:

 

[Sparx]

and another 2

its ok lampypoos, pretty sure tis' enough of us here who feel the same way.

The very simple & proven experiment -

Take atomic clocks( most accurate time devices we have) syncronise the time on both clocks. - Place one in a Jet plane and one on the ground, say on a table next to the runway. Fly the plane around the world at its top speed & then compare the time on the two clocks once the plane is back on the ground.

The clocks now read different times - the clock on the ground is a few seconds slower than clock that was in the plane.

Extrapolate this, & lets say for example BeJesus didnt die, & like so much sci-fi was beamed on board daddies big space ship. Spaceship zips off into space going the speed of light. Dadeh goes home, grabs some lunch & zips back to earth again at the speed of light. 2000 years have passed on earth, but only 20 on the spaceship. Or something like that

arnt we getting in to relativity and observers and stuff now?

 

[Lamp]

Yeah, kind of off topic...but since Job's initial post was such a crock of shite, I guess a picture of a Martian licking a women's armpits wouldn't really be terribly off topic here...

 

[Zede]

arnt we getting in to relativity and observers and stuff now?

time "machines" dont exist, but it can be proven you can time travel. Most sci-fi related travel needs worm holes & other such shizzle, thats where lamp comes in !

 

[old.Tohtori]

time "machines" dont exist

Says you.

I'm created a trans-universal traveling method, went there, built a time machine and came back.

 

[Job]

OK smartypants

All human ideas of time travel as in 'Back to the Future' rely on you stepping outside of some 'Time frame' and watching 'another you' i.e. a copy going about it's business.
As in our hero seeing himself in the future, the future you would allready know you had travelled to see yourself.

Lets' go through the first one s..l..o..w..l..y
You get in the machine and travel back 10 mins and that means 10 mins before you get in you would appear to yourself as a copy..so there are two of you.
Then one of you gets in the machine..leaving the first returnee to watch this process, then another returnee comes back but he has to see himself 10 mins ago but you're allready there...yes it's a load of bollacks but that's why time travel doesn't work because time is in our heads anyway.

The only way to travel which is an entirely human concentric would be to put the atoms back into the positions they were to recreate some long lost 'time' to recreate a historical scene which we associate with being the 'past'.


If we couldn't remember where the second hand was after it moved..it never would.
