man travels through time. reality? falsification?

dont look until you're done:

Spoiler:

topic. address. discuss.

The first one is iffy. How did he get back? I was under the impression that you could travel into the future, but never into the past. The second movie says, otherwise but only in certain types of events, from the machines conception onwards.

its cool and all but I'm starting to think were crossing a line by expecting to communicate with the future, time travel isn't something to be fucked w/. And the fact that you can only go 1 way is just a theory, we don't know for certain.

the second one is cool
i think its really interesting, tho a little scary..

the first one is iffy like jay said.. howd he get back? but i still have an open mind towards it.. i love this kinda stuff it really fascinates me

eh ok ima ask this question who believes that if a time machine is created and someone goes back in it that they can alter their present (our future)

if it were anything that for told future events or give us information in anyways, shit could get seriously fucked up.

Or vice versa... You think too negativley.

well its hard to explain what i believe but ill try
if some one sends something back to the past then its already happened
attempt to explain: say someone says they are gunna send a letter to the exact time he said that he would then the letter should already be there when he said it
unless something between the time happens to stop him from sending it

But the letter might not have gotten there yet. Or, the world that you change is actually a different possible world/alternate world. If you can change anything - then anything can happen and every world is possible.

well if time did alter that would call for everything just changing or a time line split

Exactly - however when you think about it. Assuming an infinite amount of time forward (Or at the very least, an infinite of times you can move back in time) that means that an infinite amount of time lines could happen. That means each reality has a possibility of coming true. The very most minute changes can change all of time - and they can all happen because people are in that same time more than once, and in more than more time once.

This would cause an infinite amount of possible worlds, and realities.

my theory is that, like jay said, there are many different realities. e.g. if i flip a coin the universe 'splits in two' so that one universe has the outcome of a heads and the other universe has the outcome of 'tails'.

and when someone time travels its basically going to an alternate universe in a way...





another thing. einstein's theory of "e=mc^2" states that, the faster you go, the slower time passes.

e.g, if bob set his alarm for one hour at his house, and joe set his alarm for one hour but he's flying in an airplane, by the time bob's alarm goes off joe will have a few minutes left; or something.

sooo

if joe is instead flying at 10,000 miles an hour, it is possible to 'travel into the future', when in reality they are just (in a way) going slower. basically joe is running the race slower than bob, but bob keeps going, so then by the time joe finishes the race bob is a mile in front of him.

even so, like the 2nd video says, those kinds of speeds are hard to come by. but i dont really get how the video makes you go back in time. i'd think travel to the future would be more realistic. hum.

well then that would make infinite number of universes (with the theory of the second video) for every particle that falls into the portal being thrown randomly into the past

Umm, this is silly. You can't possibly meet yourself in the future, because by traveling forward your no longer in the past, hence you have no future. Harder to explain than it seemed at first, but basically, if your not around to live your life, then you wouldn't be in the future.

you will still exist in the future as long as you eventually return to the past

But if your in the future then you weren't in the past for the time you were gone. Hence you can't exist. It's a temporal paradox.

Nah Dragon. Think it through. You go to the future, and you find no one there (No you). However, you then live your life once you return to the past. You then find that you WERE there in the future, so you actually DID meet yourself in the future. You can do anything with time travel.

It does't exist - a la we don't have time travellers coming to the past. If it does exist, humans can't and never will/have been able to do it.

or they figured out it is wrong to time travel, cause it fucks shit up hard...

yup, and this is the part where my 'multiple universe' theory comes in, it is in actuality a bunch of paradoxes and universe-hopping going on.



if you watched harry potter, the one where harry and hermione go back in time, you'll see that they avoid encountering themselves for some reason. that reason is so that 1- they dont affect themselves and possibly create a paradox and 2- so that j.k. rowling doesnt have to go on about paradox theories.


anyway if you watch a video of yourself you A- have to be there to videotape it and B- be there to watch it later.


watching back to the future, i think its #2 (where the bully guy alters the future)


OKAY clearer example...

this is your timeline. -------------------------------*-->

_________________________. -----<-------<-------<-----
_________________________ |__________________|
_________________________ v____________...____^
this is you going back in time. ---*----------------------------*->

and so you end up over here. ---*----------------------------*->

but now by messing with the past a new future is created.

its kinda like branches of a tree, theres the base of the tree, and the higher up you go the more branches, going up and down the branch can create new branches or old branches... etc. another analogy is a river, where digging a ditch toward the side of a river can divert water.

different elements of time travel are fully possible. different ways of theoretically time traveling can have different affects on the time stream. there are so many ways to theorize outcomes... but thats just it. theres a lot of ways. and theres also a whole lot of ways to screw yourself. and when you think of a paradox you get stuck in a loop and your brain starts to hurt. but eh good things to look at about time travel is back to the future, and this 'ben 10 alien force' thing which i stumbled on about timetravel.

if you mess up the past and it DOES create another time line which time line will you go to the future on? yours or your creation or a random one? hell you could end up on a random time line where all the wars never happen and science=10000000 years in the future

no, you would end up in the branched off one which you created...

did my diagram not help D:!

heck we could just be a branch ourselves...
maybe we did learn how to time travel.. fucked everything up.. and tried to fix it by stoping the creations of the machine thus resulting in OUR branch with NO definate time travel

another idea

maybe there have been people who have come to the pass and the government is just covering it up?

yes we are a branch of the time stream.

there arent any time travelers the government is covering up because we would be way different right now, but in another branch of space time there probably is.

but there are aliens that the government is covering it up.

I dont buy the first one. Its a freakin sink, your not going to go back in time, deal with it. The second however, does in fact sound theoretically possible. because if... I can explain it in my head but I cant figure out how to put it in words, so nvm. But its still cool.

like i said earlier- if you could go fast enough (without your skin ripping off or your body being crushed by G-forces), using einsteins theory of e=mc^2, you would be able to travel 'slowly' enough (time would pass slower for you), and in a way you would travel to the future,
like you might be in the 'machine' for 10 minutes but end up 10 days into the future!
