Would Time Travel Result in The Destruction of the Universe?

[ADST World]

I was debating this with someone else earlier, and was wondering what you guys thought would happen if somebody tried to change the past.

Proposal 1: The future timeline is overwritten, resulting in a infinite paradoxical loop.

Proposal 2: Multiverse theory. Each thing that is changed results in a new timeline.

Proposal 3: The creation of a new timeline results in the universe attempting to reconcile by overlapping all the timelines together, destroying the universe.

Other proposals are welcome.

For those of you wondering, I support Proposal 3.

This is Bill.

Bill doesn't time travel because he could summon Cthulhu.

Bill is smart.

Be like Bill.

Not quite the point of the forum. Are you proposing that time travel could result in the existence of a theoretical transdimensional being?

[Risottia]

Let's check with an experiment!

Evidently, no. Told ya.

If we actually accept time travel to the past as possible (but that sort of defeats the point of trying to map its actual effects, since its not), I'd go with the multiverse theory as its the least confusing.

Question: Is this a new timeline, or an overwrite of the old one?

Would (have) make/made any difference? And if so, how will you be able / would you have been able to tell the difference?

[Trotskylvania]

No, there is strong evidence to suggest that general relativity implies paradox free time travel in the form of closed timelike curves.

Time travel, if it exists and I'm not convinced it is possible, results in a situation where the transmission of information to the past results in the conditions through which that information was transmitted to the past. A causes B, B causes A.

A new timeline would start at the point you changed something. That is if you changed some event that no matter how tiny created an important ripple in time.

[Southeastern Xiatao]

I think it would be very very bad if you go back in time and change a historic event.

It's 2.
There's no such thing as 1 and 3.
It's not so easy (in fact it isn't possible) destroying the continuum.
More interesting are the (apparent) paradoxes originating from the outcomes of 2...

But is it "Time gets stuck in a loop bad" or "The universe is destroyed" bad?

[Differing Opinions]

Its always been my understanding that all possibilities exist simultaneously, so time travel in and of itself doesnt accomplish much since the travelers universe is still limited to the results of probabilty they can actually observe for themselves. It would never be possible for any one of us to significanty affect the multiverse at large.

[Eol Sha]

I've always liked the Multiverse theory. Don't know how it would actually work, but it's super cool and less depressing.

There actually two different theories, and hence further paradoxes:
In example: if infinite universes already exist before the travel, how we can create a whole new universe/timeline (the correct word is "bubble") by travelling back? That alternate "bubble" already exists before the travel, because the number of "bubbles" is infinite.
And, in all cases, you cannot change the past of the "bubble" you're departing from, nor even if you are going to thermonuclearize the whole Earth during the Tang Dynasty.

Sometimes I like to drive recklessly, just to kill off different versions of me in the multiverse.

[Chessmistress]

I don't think time travel is possible, although I'll change my mind should I see actual evidence stating otherwise. I think the universe works like a video game, in a video game the only reason you can go backwards and change things is because the past state is being stored somewhere, there is information on how things once were. I think that in our universe past timelines are not stored and once an event happens it has already happened, its results are all that we have left.

What kind of evidence?
Seeing people travelling time?
That's very unlikely to see.

However it implies a lot of complications: in example since it's a time travel but not a spatial travel you have to calculate with great precision the exact position of the planets in the very exact moment of your arrival.
Unless you're in a spaceship or something you cannot simply travel from April 13, 2016 to April 10, 2016: three days ago the Earth was in another point of the space, so you would materialize in April 10, 2016 in the outerspace, not on the Earth: you would materialize in the same point you're in April 13, 2016, but the Earth is still travelling to reach such point.

I smoked cigarettes for roughly twenty years, and wonder how many mes the cancer has killed off, and whether I should thank them for taking the bullet for me.

Ha! Risottia cannot into time travel!

[Mexar]

Time travel gave/gives/will give me a headache!

[The Derpy Democratic Republic Of Herp]

Besides, backwards time travel is impossible, silly.

[The Intergalactic Russian Empire]

You forgot one.

Set timeline:

You can't change the past because you time travelling is already part of history. Want to go back in time and kill Hitler as a baby? The mere fact that Hitler was around means that somehow you failed to kill Hitler.
