i heard something about a pole shift? of which case the earth will go out of orbit and uh the solar system will uh collapse or something

Ooooo, another good end-of-the-world scenario.  With that one, earth would still exist, but life as we know it could end.  The magnetic field of the earth is from iron in the core of the earth.  This iron is moving around, so the magnetic field moves around too.  We've known this for a while, the magentic-north pole moves around up in northern Canada, well south of the geographic north pole.

Since the iron does move around, and the innards of the earth are in constant flux, the polarity of the giant-magnet-that-is-the-earth can flip over - north becomes south and south becomes north as far as a compass goes.  This is thought to correspond to a collapse of the earth's field (since to go from positive to negative, you have to go through zero).  Everyone knows that our magnetic field shields us from a lot of radiation from the sun, making life peachy.  Some say that this lessening of our shield could cause harmful radiation to reach us and cook us, but that probably won't happen, since flips have happened a lot of times before, even since the appearance of homo erectus.  However, a flip has not happened since this whole electronics thing has happened this century.  It's been shown that sunspots, even with our magnetic shield, can disrupt electronics, communications, etc.  So a lack of our magnetic field could result in a heck of a lot of problems with our current technologies, but no one really knows.

The phenomenon is sometimes called "geomagnetic reversal"

i forget what i heard/read but it wasn't much about magnetic fields, it was more about the earth starting to spin in the opposite direction.

only 9 more days.... w00t!

honestly, im really not sure how to think about it though. smashing lead ions into eachother.... i heard that doesnt even happen in space? i dunno...

nothing i can do about it though. i saw a cool video a while ago about the LHC. i hope im not the only one who actually thought this was cool    (i know its nerdy but idgaf)

I don't think LHC can produce a singulary.  It is looking for Z0 and other particles with far less than the energy needed to make a tiny black hole.
---- do I here a sucking sound ?  ;D What is the smallest mass needed to make a sustaining black hole?

And the same would be true of anyone who existed in that sort of space, and any measurement devices they chose to use, and they would just as vehemently deny the possibility of a universe like ours existing, since it is made of weird things that wouldn't join together in ways they were familiar with.

The weird part isn't that such strange things might occur. It is that such strange things might occur all of the time, and we never even notice. Or, more conservatively, that we might be living in a universe that is the way it is because some indescribable being in some indescribable universe turned on their version of the LHC.

Sustained black holes are roughly 1.5-3.0 and larger solar masses. However, it is entirely likely the LHC will generate mini-black holes. The energies available in the TeV (trillion electron volts) will slam protons together at such energies as to compress their masses into a very, very small space. If they indeed create black holes at the LHC it will lend support to string theory with its multiple dimensions. The critical component to black holes is very large mass to generate the gravity to create a singularity. In our normal macro world gravity is pretty predictable. If you half the distance between masses you increase the gravity by a factor of 4. Now bring those distances very close (a limit approaching zero) and the gravitation approaches infinity (well sort of). The masses of the particles are very small and bringing them close does indeed increase the gravitational field but not quite enough for them to collapse into a singularity based on classical physics. If, however, the multidimensional world of string theory is correct, the gravitational effects of these dimensions will provide additional force to cause a proton-proton collision to create a singularity. Basically, if the distance between the particles increases more than a factor of 4 each time the distance is halved then the gravitational field must be assisted from somewhere outside our three physical dimensions.

Now these mini black holes will not engulf the earth and the solar system as the unenlightened fear mongers claim. Quantum physics predicts that the smaller the black hole the more energetic the release of Hawking radiation. Thus the mini-black hole comprised of only a portion of each proton (the rest is blown apart in a mass of collision fragment particles) will evaporate instantly. Furthermore, the physics predicts a specific set of decay particles to be generated as it evaporates. These particles are detected all the time coming from the upper atmosphere as very high energy cosmic rays bombard the nitrogen and oxygen atoms in the atmosphere. So there are min-black holes being created and evaporating all the time 60-70Km above us. These cosmic rays collisions are in the hundreds of trillion electron volt range. Hopefully, the LHC can achieve black hole formation.

Here's a though that will twist your noodle. Once we get to playing around with multidimensional space, it is theoretically possible to create a big bang and a brand new universe that will expand as large as our universe. Of course it will not destroy our universe as, like our universe, it will create its own space as it grows.

By the way, the girl doing the LHC rap video is a recent physics graduate of Michigan State University, my alma mater. She cut her teeth on our fully functioning super conducting cyclotron. Ok, so a cyclotron is old school but having been there myself, it's pretty freakin' impressive.

To be honest, I'm not sure what you're trying to debate anymore, and I'm not really arguing with anything you're saying.  Very strange things might occur that change the very nature of the universe and we never notice, yes.  And the LHC might do that, yes.  And there may be other universes where strange matter is the norm, yes.  But all I was talking about is if stable strangelets came into contact with atomic nuclei here on earth in our current universe.  The result of that would be that the matter would be become strange matter, and it would obviously be strange matter.  There's no "within the system the measurement won't change", because the system would cease to exist in any form that we recognize.  There would be no more test chamber, no more measurement sensor, nothing but a big hunk of strange matter with the quarks that used to be us floating around inside.  I don't know about any other sentient beings in alternate universes, all I'm saying is what would happen if these hypotheses are correct and strangelets, as hypothesized, were made and caused the reaction predicted by the theory.  Strange matter might be normal in another universe, but to us, we would cease to exist in any recognizable form if *our* matter was converted to strange matter.

If I recall correctly the LHC does it's first experiment 10/10

lol @ "The European Organization for Nuclear Research (CERN)" so EONR = CERN does it?

my theory always was that: if antimatter was created with the LHC, the (anti)mass created wouldn't have the same mass as the earth's. if, say, 1 gram of antimatter was created, then it'd neutralize with 1 gram of matter.

the LHC is a particle accelerator and it works with THAT: Particles. particles dont have the mass of the whole earth, they can form one but they wont if they're isolated or in little groups
(yeah i know this sounds retarded, but that's what i use to justify it to everyone)

^Absolutely true of anti-matter vs. "normal" matter. But strange matter (if hypothesized correctly) doesn't work the same way. Anti-matter, when interacting with its opposite, annihilates, and both are destroyed/converted to energy. Electron + positron = gamma rays, but no left over particles or matter. But according to at least some hypoheses, a strangelet + normal matter = a bigger strangelet. This strangelet could therefore convert MORE matter into strange matter. There's never an annihilation step, just a strangelet consuming more and more until everything it can possibly touch is all one big hunk of strange matter.


Yeah, it's confusing: strange matter, dark matter, antimatter; very hard to keep it all straight sometimes.

On 10th of september at 4:30 AM (New York Time) 10:30 AM (Greenwithc time) the LHC will be turn on...
I live in the center of Italy, very near to Suisse and to LHC.

We have to hope that the law of Hawking is true, and the black hole will evaporates.
Maybe John Titor had not say a lie...

Heeeyy John Titor, you have read about him too ??

Yes I have read about him from some years ago, from 2004. I know some things of him...
He can be a "clown", but, who knows... He's very fascinating, and has captured my attention.
I have also seen a documentary (in italian language) of him, and it have explained some misteryous things of him, And some things that John had foretold are been happen (such as the crazy cow).

And he has told that he go across the time by a little machine (500 pounds of weight) that can generate mini black hole, and then it can make a snatch in the space-time net.



I have found the laser test of John's trainer in the 2035. The trainer shows that a laser beam is curved by the gravity of the black hole machine... I want one of these...

Sort of amusing that one would think that gravity should create a huge lensing effect, way beyond that of stars, yet neither cause shifting of the beam due to space bending, nor pull on the guy holding the laser...

While it would be cool to have the ability to create localized gravity wells on that sort of scale (the possibility of an Alcubierre drive comes to mind), it isn't exactly congruent to modern physics to be able to change the rate at which the influence of gravity drops off. And that is what you'd need to do in order for such a picture to be made. Heck, space around the anomaly should be curved enough for light to redshift close to the beam.

A simpler explanation is that he's influencing the light in another way... say, like, with a leaky fiber, or shining light on a squirt gun.

I'm just saying...

Oh, and... a mini black hole needn't be a big deal, even if it's stable. It wouldn't swallow up more than a few atoms here and there, and if they do end up being created by the LHC, then they've certainly been created in the atmosphere already, as noted by another poster. Similar things go for strangelets, as I recall. As for mini black holes, a charged, spinning black hole of a certain size and mass could be modeled as an electron so far as I know.

That said, once one exceeds the power of known cosmic ray events, it's time to invest money in a sandbox; i.e. getting it into space.
