oh yes i know about this, it's quiet a fascinating theory and it's been reported wrong in almost every news paper i've read...
Basically (and i mean VERY basically) every thing that can happen at a given point exists as a possible event, i could press any of they keys next for
example - it's not until i press a key that the 'waveform collapses' and it's settled - this all comes from the debate about the double slit
experiments done with photons and Schrödinger with his boxes of cats.. anyway...
Well cutting a very long story too short Schrodinger then put his friend in the box (metaphorically) - because only the friend would be aware if he
was alive or dead and couldn't know that he was dead schrodinger proposed (to point out how silly this whole debate was) that his friend would have
to survive... untill someone else opened the box and could choose the possibility that death had happened...
A tree of possible events is formed, at the moment we are at a point where soon the LHC will turn on or it will break again, if we assume that it is
turned on and a massive event kills us ALL instantly then who is left to know about this? (yes jesus lovers this is the one point science needs a god
for, to destroy the world but i digress)
The THEORY then goes that because we can't exist in a world we don't exist in and we need to exist to experience the world... we reset back to a
point that we DO exist, the most likely next alternative that doesn't end in out death! This is of course that a stray coupling should do so much
damage, etc, etc... It could be impossible to collide two hadron particles faster than a certain level, we might NEVER in all of history and science
manage to do it.
It's been suggested that it's impossible to die, easy for other people to die but for that magic person who is using the word "I" it's absolutely
impossible - test it out! haha you didn't did you? because it would be impossible, you WERE going to but then IT moved you to a existence where you
didn't quiet trust me enough, every time you almost die it resets to a position you're safe... haha hmmm..... PLEASE dont try it.
Absolutely wonderful thought experiment, alas the world developed slowly over billions of years without us - or so we think - and "I" didn't exist
before "I" was born......
so in short, its an interesting concept that blowing ourselves up isn't going to happen however it's also a load of old hogwash.....
some people, scientists among them - think that some agency from the future is sending spies back in time to make sure we don't destroy the earth -
of course this makes no sense, you need a first time clear route before you start messing with the time lines, unless some crazy agency from a new
dimension is trying to mess with our natural timeline - you can't go back in time and be your own grandfather but you CAN go back in time and kill
your own grandfather as a child, the cern situation would be like the former not the latter.
anyway in the interest of full disclosure i should tell you that i only know most of this stuff because i met a time traveler (who didn't think
smashing particles into each other was very interesting or dangerous /btw)
