What would happen in this time travel scenario?

Hi all, I'm not one of the pranksters on here or anything, just have a time travel scenario I'm curious about....

I've known my best friend since pre school and he was depressed about his mom dying so he killed himself this year 2008, he was only 21. Say I found a way to go back in the past like in 1999 when me and him were 14/15, I pulled him aside and told him where I'm from, what was gonna happen and talk him out of it.

What, exactly, would happen after I told him and when I got back to the present? Serious answers please.
 
IMHO

Don`t mind about paradoxes

`cause you will return in a parallel Timeworld, maybe all the variables are not equal -called it DIVERGENCE- so his mother will not have the same problem... and maybe you are not a friend of him...

the problem is if your time travel device don`t have a good VGL, cause you will not find your original timeworld...

that`s it...

and if you got a good VGL system the only seundary effect shall be a "altervue" event, in other worlds you end with memories of both timeworlds...

On top of that, broent, It actually wouldn't even be your friend.

All is vanity.

You seek a ghost, of a image, that only exists in your mind.

I would be nothing but a waste of your energy.

recall15,

I'm sorry I do not get what you are saying here.

>Don`t mind about paradoxes
>`cause you will return in a parallel Timeworld, maybe all the variables are not equal -called it DIVERGENCE- so his mother will >not have the same problem... and maybe you are not a friend of him...

How would the variables not be equal exactly? And why would I not be a friend of him anymore? That doesn't make any sense. I go back there, tell him whats gonna happen, therefore saving his life - So that makes him not wanna be my friend?

Ok, what on Earth is a VGL? I have never heard of that before. I'm not familiar with these terms, wherever you're getting them from. I get the part about ending up with memories of both timeworlds (of the one he died in and the one hes still alive cuz I saved him), that's kinda what happened to Ashton Kutcher in The Butterfly Effect.

Kanigo2,

Ok, what you said is confusing me more than one the previous poster said...

How would he not be my friend? Why? What do you mean all is vanity?

The last thing you said - You seek a ghost of an image that only exists in your mind. Ok I dont see what that has to do with me going back in the past, hypothetically speaking, and saving him? Obviously I would be in the past and he would be as real as can be. If you are referring to memories, then yes what you are saying makes sense he is practically a ghost now that hes dead and he remains as an image in my mind of the memories I have of him. Other than that, I don't see why this whole ghost/image thing has to do with my time travel scenario.

it`s a Multiverse out there -------> infinite Timeworlds ------->no paradoxes!

if it where 1 Universe you will right! only one timeline...

Ok, what on Earth is a VGL?

VGL///
quoting John:

Timetravel_0: Good question!!! That one almost never comes up. The hard part of
traveling through time is not the bending of gravity but the plotting of
your course and holding to the basic "position" in your environment. This
is done through a system called VGL (variable gravity lock). Basically, the
unit takes a reading of the local gravity and samples it during the "trip"
in pulses. If the gravity is too far off, the unit stops or reverses itself
to the last sample period where the readings were correct. If there is some
sort of failure, the unit shuts down and drops out to where ever you may be.

Re: What would happen in this time travel scenario

Broent, here is the real catch.

If you went back, ONE DAY!, and met yourself.

Is it really you?

Or do you have some , objective, feeling and concern about a person you never met?

You think that person is you, but it is not.


You are Vain, you believe, even images of yourself to have value.

You couldn't possibly believe, for one second, that there are two of YOU.

That would require a LOT of energy, to make two of you.

Could you?


Is this the paradox Your Vanity has created?


----------------------------------------------------------

So lets suppose, that you were able, to violate Newtons second Law, and created energy

BEFORE IT HAPPENED

Being you, in this same universe, same timeline. Even then, would you still believe, that that was actually you?

All is vanity.


The energy required, to perform an act on the scale, that you speak of, has been calculated.

Trust me, you do not have enough.


Now, If you wanted to go into the future, we can accommodate that, for SO MUCH LESS ENERGY.

But that would require, for "you" to leave this place. Then upon your return, you can meet your great great grandchildren.


Which is also VANITY.


The mechanics, of such a circumstance, apparently is not, incapable, because you have though of it.

My opinion on the matter is that when it is all said and done, you will realize, Even traveling back one day!, that it wouldn't be you anyway.

Go, look in the mirror, that is as close, as YOU will come, to seeing YOURSELF in the past.

You wanted serious answers that address your base question.

We don't know whether or not time travel is possible in this particular universe.

We don't know if the Many Worlds Intrepretation is correct. At this time it does appear that it is wrong, at least on the macro physics level. It's certainly not a well received interpretation of quantum mechanics in the world of quantum physicists. If it is wrong and if time travel is possible then we have serious problems with paradoxes.

So, you have a time machine and you want to avoid the suicide event through time travel. Let's change the scenario slightly so you can get some perspective. Rather than traveling directly to 2000 you first travel to 2016 to see how the lives of people close to the two of you have played out during the ensuing 8 years. You see, for instance, that his girlfriend has married, has a coupe of kids a job, new friends, etc.

Now you go back and save him from his fate. Next you revisit 2016. He's married to the girlfriend, they have their own kids, the old kids don't exist, the old husband is married and has his own kids. As you check the situation thoroughly you discover that hundreds of marriages are changed because of one husband-wife switch. In other words you've set in motion a cascading set of events that result in an entirely new set of people that didn't exist in the original scenario. The world is completely different if you consider just one factor out of thousands of possible factors - children born from changed marriages.

And there's no guarantee that he won't suicide anyway over some other issue or that his life will be happy. We all lose our parents and a lot of young people lose their parents. But few suicide over the event. Suicide is rarely brought on by a single event nor do otherwise psychologically sound people suddenly suicide even over exremely traumatic events. I suspect that there were other long term contributing factors that led him to suicide.

Note: Disregard the VGL and "altervue" comments. Those terms are taken from the John Titor Saga. Apparently someone doesn't "get it" that you're hurt over this event, want serious responses and he decided to yank your chain for grins. (Adding to that that he doesn't speak English as a first language might explain why he missed the sorrow in your post.)

All is Vanity.

This is no more than a Dogma Response, to a Karmic event.

You are better for having experienced what has occurred.

I hate doing this, (because I cannot stand one liners)"That which does not kill us makes us stronger." Friedrich Nietzsche.

-------------------------------------------------------->

There is a lesson here--what exactly it is, is for you to figure out, brnoent.

Knowing things the way I do, you won't ever get an answer.

I hold my advice for a later time, because like most advice, It has no merit and will be misinterpreted.
 
Ok... let me have a go at this....

Lets say you had a time machine in front of you right now and you knew it worked - to go forwards and backwards in time...

first you will need to decide how to overcome these problems...

1) How are you going to explain away how you have aged several years in just a few days (remember he will be 14/15 and you will be the age you are now - but to him he saw you as being 14/15 probablly a few days before you arrived in the time machine.

2) you better make damn sure that you look at the date and the EXACT time you leave - and then make sure you return to your present AFTER you left! you dont wanna be bumping back into yourself on your return trip to "now"

3) also you better make sure that when you visit your friend you are not going to bump into your past self either - i mean its no good knocking at your friends door to find your past self is already there as well!

ok so now on with what would happen if you tried to stop his suicide....

- you may find out that no matter what you do he will still suicide or die in some other way (to keep fate in check if it exists)

- you may find out that your going back in time was the whole reason he did that in the first place "gave him the idea by warning against it" - and that this has always been what happend - eg he always commited suicide because he got that idea from you and then did it - and then you go back to stop it but end up just giving him the idea. - a loop sort of

- you may find you manage to pull it all off and he doesnt kill himself - don't expect your timeline to remain the same if you do that - things will be very different when you return (and he may or may not still be alive when you return to your "present"

- the many worlds theory may be right and the moment you stop his suicide the universe branches off in 2 - be aware that you will then change universe timelines and things could be amazlinglly different from what you left in the present.

- also its impossable - because if you do ever do that - then it would already be done - the past/present/future are in constant flux (maybe? lol) and say you started building a time machine in 10 years from now - and it was finished in 20 years from now - so 2029 - and you get in it and go back into your past (even now its the past to you) and stop the suicide - your present is then the future from that event - and therefore your friend would be alive now (if this is all one timeline of course) so you can at least deduce 1 of 3 options from that....

1) you never manage to make or get into a working time machine.

2) you do make one but are unable to stop his death because the universe stops it somehow.

3) you do make one and manage to stop the suicide - but then branch off on a new timeline and get stuck there.

remember that if none of those happend then your friend would be alive now - as you would have already changed your past (even if you do that 50 years from now) - its still in your past from where your sitting now.

I know this is probabbly not what you wanted to hear but you did say sensible answers - and i didnt wanna feed you some sort of rubbish just to make you feel better - thats not scientific at all.

(p.s. - if you (or anyone else for that matter) doesn't understand any of this let me know and i will try to explain it better.

Don't confuse Many Worlds Interpretation, an interpretation of probability wave functions in quantum mechanics, with what Dr. Kaku was discussion relative to cosmology. He wasn't discussing the nature of a quantum probability wave function. He was explaining a theory of cosmology that suggests that more than one independent universe could have evolved from a single Big Bang event.
