have to agree with you Carla. plus there doesn’t seem to be anything to back up the claim that they took their lives seeking to travel back in time only that they were afraid of the punishment the girl who lost the key would get… the time travel reference was stated in her note as a wish and not a reason exactly. very tragic story…

@ Carla . you are spot on the idea of a 12 year child with the idea in her head to kill herself is shocking.
What sort of world are we all devoloping.

Cool, il give it a read later. It sounds very deep, plus I seen that episode of futurama + suicide booth. Could this be the future???

It’s so cool that my comment was removed and now you reply to yourself :) I cannot blame them, it looks crazy and fake, maybe offensive to some. I was also in shock when I found what modern understanding of the universe is after I read book by Micho Kaku (Parallel Worlds ) and the Grand Design by Stephen Hawking.

I was only saying what I learn from respected open sources and that idea of time travel by suicide is not that bizarre as it seems. Ok, now, remove it.
You like it or not but you cannot remove this from wikipedia as well:

http://en.wikipedia.org/wiki/Many-worlds_interpretation#Quantum_suicide_thought_experiment

It has been claimed that there is a thought experiment that would clearly differentiate between the many-worlds interpretation and other interpretations of quantum mechanics. It involves a quantum suicide machine and an experimenter willing to risk death. However, at best, this would only decide the issue for the experimenter; bystanders would learn nothing.

That’s just a thought experiment, a tool to explain a concept by analogy. It’s not actually real, as physics does not work like that on a macroscopic scale.

My apologies but this observation is not necessarily true. You will know if you go through this experiment :) the fact that wave function collapsed and you appeared in this universe cannot automatically mean that other universes are not possible. Have you read the Wikipedia article linked? What about alternative histories which all happened, is it not macroscopic scale?

Of course is just a theory but it is a mainstream theory. LHC was built to prove it.

Yes I did read it; I also have a reasonably good grasp of quantum mechanics and its various interpretations (Many Worlds, Copenhagen, Heim) as I’m a physicist.

The LHC wasn’t built to “prove” anything, and certainly not to prove that the Many Worlds interpretation of quantum physics is the correct one. It was built to test a wide variety of ideas in order to verify or falsify them, in so far as is possibly the LHC.

For anyone observing; Conor Farrell = correct, angryzes = Wrong.

Many worlds intrepretation is ONE possible intrepretation of quantum mechanics. Others include Copenhagen, Ensemble, favoured Higgs space etc and they are ALL speculative. We simply don’t know, and indeed, it’s likely we will never be able to test it which is why we call them intrepretations rather than theory. Wavefunction collapse is hotly contested, and in some versions not required. Is it because of this, for example, I tend towards emsemble version which treats the wavefunction as entirely probabilistic.

The LHC was buil for thousands of reasons, but not the one mentioned – it’s highest profile job is testing the Higgs mechanism to see how particles acquire mass. Quantum suicide is a thought experiment – a consequence of CERTAIN versions of Many worlds. And the operater would still be quite dead or maimed in the majority of worlds after the timeline split. In any case, you cannot travel between worlds as the history line splits and forbids it.

Dave, also a physicist.

I am sorry Conor, Dave. I am not a physicist but I am a software developer and I know what logic is. Why to argue if you actually agree with me? I never said that it is anything more than theory but you guys, tell what is and what isn’t with such certainty like you know it :) I do not care what you beleive in – just prove multiverse theory wrong and then we will start to talk. You may start with m-theory and 11 th dimension.

I know that LHC was built to find some certain particles which may prove that theory wrong or right. We cannot prove it right or wrong here :) Moreover, dear physicists – please explain why do you think that if this one is “just a thought experiment” – that it cannot be actually implemented? Are all “just a thought experiments” are not possible perform in reality? I think the only impediment that there is no brave scientist who want to try it and also the fact that observers will not be able to know if it was sucessful.

I don’t think either of us said anything about being certain of anything, as you said. We can’t be certain, as physics hasn’t given the answers just yet. We just said that thought experiments are analogies and that there are many more interpretations of quantum physics.

You are also implying that we don’t “believe” in the multiverse idea: I, for one, am actually quite fond of that interpretation at the moment. Asking for one of us to prove that the idea is incorrect is pointless, as neither one of us said it was incorrect, and the definitive evidence to build such a proof are simply not there yet.

“…just prove multiverse theory wrong and then we will start to talk. You may start with m-theory and 11 th dimension” is a very loaded statement, where you appear to be implying that if it can’t be proven, then it must be correct because you want it to be. You should note also that M-theory involves two types of branes: ones with 11 dimensions, as you said, but also branes with 26 dimensions which you left out.

Hm, kind of feel why you can be either mathematician or physycist – so, we kind of agree, is it not? My only statement was that “idea of time travel by suicide is not that bizarre as it seems”. And, as far as I see – you agree with it! ( and I agree with you ).

… 26 dimensions … and it’s not the end. I have a suspicion that there is no limit. It is like a piece of paper looks like 2d object but it is in fact 3d object. Why not to have 26d piece of paper and claim that it is actually in 27d object, just 27th dimension is so insignificant that we ignore it. If you ask me what I would prefer – I would prefer 42 dimensions, just for fun.
