Time Travel Paradox

wendell borton

On her 30th birthday, a woman who wishes to build a time machine is visited by a future version of herself. This future self explains to her that she should not worry about designing the time machine, as she has done it in the future. The woman receives the schematics from her future self and starts building the time machine. Time passes until she finally completes the time machine. She then uses it to travel back in time to her 30th birthday, where she gives the schematics to her past self.
So it responsible for designing it in the first place?

She did it in the first place herself in the future, then travelled back once.
Easy peasy.

The Backwards Man

The woman. Even if she didn't go back after she built it, she would still have built it.

By the way, travelling back in time is a load of balls but that's neither here nor there.

Trick question. No women would be capable of building such a machine.

Is that the film where your man has his head transplanted onto a fly, and the fly's head was transplanted onto the man?

Shudder! Imagine waking up with that frightening, hideous, creepy thing on your neck?

Take a look at the 'many worlds' theory - i.e. every time you travel back in time and change something, you're creating a new universe. In one universe the woman would have been responsible for designing the machine. In the second, alternate universe, she simply would have constructed it from a set of plans given to her by an alternate version of herself.

I know, let's say it was higher dimensional beings.

Everyone will buy that?

Yes. They're the only ones who've realised the physics are impossible.

We can no longer travel back in time. I've only done it twice before. Once to start the loop, and a second, more dangerous trip to close the loop. Any further disruptions to the continuum would be disastrous, to say the least.

Watch predestination, you'd love this movie.

Sounds like the type of thing that would preoccupy the mind of a student studying philosophy. Scraping a pass because they smoke way too much cannabis.

The usual profound insight of a stoner. The same insight as the alcoholic, only with a real belief that their drug has virtues that make it very different.

And travelling forwards isnt? I mean huge leaps into the distance, not gradually minute by minute.

razzler

If she travels back in time IN the machine, why bother giving herself the schematics? Just give herself the actual machine. Oh, I see. The machine probably sends only her back, while the machine remains in the future. But then she's stuck with her younger self.....

I've built a time machine that travels sideways :smug:

Behold! A time traveller from the 50's walks amongst us!

It's an impossible situation because once she went back to her 30yr old self shed start gossiping and yapping about stuff and would forget all About time. Then she'd snap out of it and have lost the keys to the time machine or find it was so badly parked that she's now blocked in by someone else's time machine. She'd have to stay the night with her 30 year old self and they'd have few glasses of wine and end up crying about mistakes they both made and stuffing their faces with cakes and chocolates and decide to go to a late wine bar where she'd get her self arrested and locked up for drunken behaviour missing the time portal opening and getting stuck in the past. Her 30 yr old self wants nothing to do with her and she ends up homeless and on the streets. The time machine never gets built and none of the above ever happen.

There are billions, probably billions of billions of time machines in the world.

Time is a concept created by humans. There is no past or future. Energy is just continually changing from one state to another .

So it responsible for designing it in the first place?

can we please get copying and pasting of stuff from Facetwit banned?

I call shenanigans. I stood 9 foot away from my mirror (against the wall, no less) and didn't see any dinosaurs. :pac:

It's all the one. It just so happens that humans are fitted with one forward crawler gear. I have it on good authority that dogs - particularly Labradors - know a lot more than they're letting on.

Was it a large off-road 4x4 type time-travel machine for bringing the kids to school yesterday?

If you travel back ten years to when they still existed, then yes

I've a cat in a box at home... he's been there for 5 years.. .I don't know if he's dead or alive.. I don't want to observe.. because then it'll be definite.. dam this thread!

I thought this was some kind of spoiler and referring to the film,
if you're referring to xtra vision, then didnt they only go out of business last year? then again, Ive no idea what time you are from and I suspect you've let it slip you are actually from the future, so boards must be acting as some kind of a conduit, I'm sure its quite possible you didnt realise this.
Could you by chance pm me the numbers for the lottery this week (here at my time), everything from Friday the 12/12/14 till say the following Monday.
If you give me your name and address in my time I'll split the winnings with you, obviously its not in my interest to do anything nefarious otherwise you'll never be able to send me the numbers, and probably best if I just secretly gift you the money now in my time, tomorrow in your time when you awake you'll be rich, as soon as you forward those numbers on.

Lets not concern ourselves about the consequences of ripping the space time continuum a new one, we'll probably be in different realities by then.

there is no paradox , either time travel in reverse is not possible or its possible but it creates a different timeline in a different universe

Silly boys, you needed a sledgehammer to knock the wall down as you obviously weren't far enough away. doh!

but for those of you wondering how,

light travels at a constant speed, if your mirror was 186,000 miles away it would take the light 2 seconds to travel there and back, therefore the image in the mirror would be 2 secs ago, a glimpse in the past of what you were doing 2 seconds ago

If it creates a different timeline in a different universe, what happens the old one? from my reading of the Primer example,

those that witnessed someone get into the box in their timeline subsequently saw them comatose in their timeline

Ok I think I answered that myself, so it seems different timelines go on, in different places/universes/wherever but

someone that travelled through time cannot exist in the new timeline, only, the person that exited the box/entered the new timeline, is apparently not the same physical being that got into the/a box and left the old timeline? as that person is comatose in the original timeline, but the new incarnation that exited the box seem to be able to exist at the same time as their previous incarnation at an earlier time, but who is also a different same person because they are in a different timeline/universe. I was wondering how the two people could exist in the same timeline, but after the point which the first person gets into the box (even assuming that happens in the now alternate timeline) means they die and both of them only exist for the time until the original person in the timeline gets into the box, does it matter which of them gets into the box? does this create a new alternate 3rd timeline? and then continue on? is there a finite limit to the amount of realities/universes that can fit into, whatever they fit into?
What happens if there is some event/accident where the box is damaged before this occurs? or the person who appeared out of the box intentionally or accidentally kills the person who was meant to get into the box? or they decide or are persuaded not to get into it?

Time travel isnt possible for people in the way suggested, not yet anyway and if it ever is I think that would wrap things up, if it were possible it would be too confusing for us to understand, Im suprised that Doc didnt kill Marty or vica versa in Back to the Future. Even Biff would have being doing a service to all if he destroyed the delorean after he stole the almanac.
