Going back in time.

[The Nuclear Fist]

To me this paradox seems not to be that well thought

It's actually the most likely time travel scenario. If you go back in time to alter an event (and succeed), yourself in the present will never need to go back in time and change the past, which will in turn cause the event to happen anyway, which will in turn cause you to go back into the past and alter it, which will in turn cause yourself in the present will never need to go back in time and change the past, which will in turn cause the event to happen anyway, which will in turn cause you to go back into the past and alter it, ad infinitum.

Any time you go backwards in time to change an event, you will naturally put yourself into a loop. However, there exists a subcommunity who believe that if timetravel is actually feasible, simply thinking determinantly about going back and altering the past is enough to trigger the loop. This, among other things, help to bring the mountain of evidence against the idea of time travel.

The past is already determined, so any alterations have already been made.

Here i disagree
Say i return in time and for some reason i kill my mom
Now it only seems logical to me that i continue to exist,regardless if another me will be born or not,it's just that the new future will be diffrent and I,the killer will exist without I,the time traveler being born again.It's quite logical actually,kind of fucked up but logical

[Krakke]

I'd bring a flamethrower to the middle ages. IDK why. Maybe so I can cook some knights like spam in a can.

The past is already determined, yes. And so thus attempting to alter it will only result in the time traveller being in an infinite loop. Changing the past will result in you not changing the past.

I think you're mistaking it for the multiverse theory, in which your actions result in the spontanious creation of an alternate universe in which your choice was different.

regardless if another me will be born or not,

By going into the past and killing your mother, you will cease to exist and will therefor never be able to go back in time and kill her, resulting in you being born, and going back in time and killing her, ad infinitum.

it's just that the new future will be diffrent and I,the killer will exist without I,the time traveler being born again.

That doesn't make any sense. You, the timetraveller, and you, the killer, are the same person. By ending the life of your mother, you are killing yourself and killing your chance of going back in time to kill her. Which will cause you to exist, and to go back in time to kill her.

It's quite logical actually,kind of fucked up but logical

It's hardly fucked up, and illogical in every way possible.

[Great Nepal]

I would take a nuclear submarine loaded with a lot of Trident D5 back to late 1800s; sail it to Thames river, destroy London - then demand all of British Empire (except UK, obviously) to be ceded to Nepal or "rain of destruction will be brought"... After that launch another missile on Paris and demand all of French empire to be given to Romania. After that, launch another missile at St. Petersburg and demand its European half to be given to German Empire.. After that nuke Washington DC for fun. Then maybe give loaded submarine to Nepal government so that they can hopefully reverse engineer it...

Seeing as how you exist, Mare, it is impossible for you to ever go back in time to kill your mother before your birth. You never did it, because you were, in fact, born.

I doubt Nepal at that period could reverse engineer a tin opener, and who would your crew be for the nuclear sub - there can't be that many deranged Nepalese nationalist submariners around?

[Romania Mare1]

You, the timetraveller, and you, the killer, are the same person.

Once i travel in time i no longer am the same person.
Say i travel to in time 10 years and meet myself.Am i the same person ? No,we are diffrent persons,hence if i kill that version of me i can still live,the sequence of my appearence seems irelevant to me and i don't think the universe would care if i was born in the first place,i would just exist

[Autash]

Why are we arguing paradox theory versus branch universe theory versus static timeline theory again? I thought this topic was supposed to be about what we would do for lulz with the power of technology.

Reread the underlined part.
I will hope they will manage to do it... if they cant then - ah well. They still have one of largest empires along with Romanian and German.

Yeah, but still the idea of lugging a nuclear submarine up the Himalayas to "give" it to Nepal is rather comical.

[AiliailiA]

I like the idea but wouldn't it be more logical for you to actually continue to exist in that plane,hence the future is modified and you simply live in your current version.I mean why does reality have to undo itself ? To me this paradox seems not to be that well thought

Hence why I claim credit for something that actually happened.

If you could take a piece of modern technology with you back in time, what would it be and for what purpose?

I'd take some of Benjamin Franklin's research notes on electricity to some Roman scholars.

It seems you chose the wrong Roman scholars, or else they couldn't comprehend your barbarous Latin ...

Because your efforts have left no noticeable mark on history.

Me, I'd take some newspapers and I'd go visit Mikhail Gorbachev in 1982.

[Bears Armed]

Austria-Hungary did poorly against Russia and (Considering the numbers involved) Serbia. It performed admirably against Italy, and considering its incredibly small resources, its performance in the mediterranean (Well, Adriatic) was nothing less than astounding.

I forgot to mention this before, but -- in case you didn't already know -- one of its naval officers in the Adriatic was a certain Captain von Trapp... Yes, the one whose later family life inspired 'The Sound of Music'. How many of you wish that his submarine had been sunk with all hands?

[Kalysk]

Who are we kidding here? All of us would die if we went back any significant amount of time. Whether it be bandits on the road, slavers, or being caught up in a war. Plus, you can't even speak the language of the people you'll meet. You know how foreigners were often dealt with back then?

Here's some further extrapolation on this topic.: http://www.cracked.com/article_18564_6-time-travel-realities-doc-brown-didnt-warn-us-about.html

[West Cork and Kerry]

I would send off some hydrogen bombs for the Old IRA to use against Britain in 1916 to get full Irish freedom.

One can get around that.

For instance, I could go back in time, buy Microsoft stock shortly after creation, then send myself a letter/singing candygram to go back in time and by Microsoft stock.

Loop closed.

[Arumdaum]

I wouldn't, honestly. Only if I could go back.

Then I'd bring modern medicine and solar power to the world, as well as public transport.

Pretty much all of that can be dealt with, though the Cracked article is accurate as far as more modern times go. You could easily drop back to the 18th century, though. Documentation would not be common and what minimal records you'd need could be faked. The dietary issues are harder but not insurmountable, nor is the language. The farther back you go, the more difficult it becomes, of course. Still, it would be possible to acquire a decent working knowledge of Latin, for instance, or koine Greek. Money for ancient times could easily be faked (the Romans actually had no laws against counterfeiting; you just had to get the weights and composition right). One problem might be carrying enough of it to get by on.

And don't such a spoilsport.

[Sibirsky]

Too many variables about how the thing you took back could influence the "present", for all you know it could end up changing the timeline so Hitler won WW2, or some such. Just too many paradoxes in general, but if I did take something back with me I'd take some modern scientific knowledge and give it to some ancient culture.

i would only change my, and those I am close to, pasts. For the better of course.

[Xsyne]

I'd take as much hydrogen peroxide as could be manufactured back to approximately 3.8 bya. Anything I would do would have unintended consequences, so I might as well just not bother with intended consequences and instead try to make as many consequences as possible.

I get a feeling that turning Sengoku Japan into THIS would be my mission in time travel.
