back to article Triumph in Geneva! LHC beams up and running again

There were emotional scenes last night at the headquarters of underground international atom-smasher science alliance CERN, as joyful boffins celebrated the successful restarting of the Large Hadron Collider. The colossal machine circulated its first beam around the entire 27-km supermagnet circuit at 22:01 Swiss time, and sent …

Yet Mr. Hawking’s theory has never been proved and it contradicts Einstein Relativity. So to prove Mr. Hawking right, 2 experiments were devised last year: a satellite called Fermi was launched to detect radiating black holes in the cosmos, but it failed to find any. A second test was done, manufacturing superfluid condensates, similar to those CERN will make with quarks; but formed with lighter, inoffensive ‘electro-weak’ Atoms. Those ‘atomic holes’ rotate 1 million times slower, absorbing sound ‘phonons’ instead of light ‘photons’ - reason why they are called dumb holes, instead of black holes. So, this June in an experiment at Haifa, Atomic Condensates rotating at supersonic speed became Dumb holes and absorbed sounds. Problem is they didn’t evaporate, proving that Quark Condensates, made at CERN, will absorb light & matter without evaporation. Because in Nature all what is possible happens (Totalitarian principle), Quark Holes should happen at LHC, making prohibitive for Public Policy the risks for Earth of a quark factory in this planet. CERN affirms LHC carries no risk, but critics contest neither Haifa or Fermi showed evaporation and the Company’s safety report doesn’t study Quark Condensates, which were little known when the factory was designed.

Evidence showing the people at CERN aren't being responsible with this physics malarky is already popping up, and if they can't be trusted to use their newfound telekinetic abilities for anything better than posing for photos, what happens when they really start smashing atoms!?

Quite: But about black holes...

Some very learned scientists have postulated that the largest black hole generated by the LHC is itself.

It is of such enormous dimensions that money disappears into the LHC-BC never to be seen again: In this universe.

@luis sancho

The highest energy cosmic rays are vastly beyond what CERN can manage. They've been hitting Earth, and everywhere else, for billions of years. We're still here.

Lots of other places in the Universe go way beyond anything we can make. Only the most extreme of all become black holes.

But that doesn't even slow down the people yelling "Don't cross the beams!"

Re: damocles sword

You're missing the main reason for which LHC is certainly safe: this type of collisions, and even more powerful ones, happen routinely in Earth atmosphere when cosmic rays collide. If smashing atoms together at high speed was enough to create stable black holes, it would happen all the time. We wouldn't even have stars.

The rest of the safety report is just decoration. You could disprove all of it, and LHC would still be demonstrably safe. If black holes didn't evaporate, all that would mean is that the nanoscopic ones created by high-energy collisions disappear in some other way, but they can't be stable or we wouldn't be here. In fact, finding out something like that would be a major success.

WTF

I had no idea it was restarting but last night I felt most peculiar, honestly, the unannounced event being just a few kms away.

I first became suspicious whilst having a late supper when the cutlery disappeared off the table and out the window heading in the general direction ofds CERN. This morning I was decidedly suspicious when I noticed that my bicycle was missing.

As for quark, well my missus bought some this morning from the local farm and they mentioned that bizarrely an awful lot of it had appeared overnight and they were happy to sell it off by the bucketful...but their metal buckets had disappeared so it had be plastic. Tastes a bit different as well, a bit of a burnt milk taste, hmm.

I think I will head off to the DIY store this weekend and see if I can buy as many as possible big brackets with very big screws to try and lock down the wife, kids and the goldfish and hopefully stop us all disappearing across the "event horizon" next Tuesday at 13.13 (French time that is, not Swiss, to be not quite as precise).

Just like stuff in the LHC cosmic rays are particles that travel close to the speed of light. But cosmic ray head to head collisions are extremely rare. I question the reassurances.

I want pictures of Alyx Vance ... no, NOT Ashlee Vance!

"Just like stuff in the LHC cosmic rays are particles that travel close to the speed of light. But cosmic ray head to head collisions are extremely rare. I question the reassurances."

You might then want to peruse this: http://arxiv.org/abs/0806.3381 No, I don't understand the math either.

Note that cosmic rays may have far more energy than particles found in the LHC beam pipe and that "black holes in LHC" (N.B: non-stable ones; to all intent and purposes, it's just short-lived particles at that point) comes from people looking for extra dimensions to stuff stringy branes into, which sounds just slightly more plausible than purple cotton elephants dancing on your front porch when your are not looking.

But it's fun speculating: http://www-atlas.lbl.gov/physics/Sven_Black_Holes_with_ATLAS.ppt

"And whats all this about getting no radiation from a black hole when there are many beautiful pictures of great arcs of colour that are explained as X-rays from a black hole causing fluorescence"

That's not Hawking Radiation. That is radiation and accelerated stuff coming from the black hole's accretion disk, i.e. matter being seriously compressed until it squeaks. Only black holes of very small mass (primordial Black Holes evaporating to nothing in front of the camera right about now) yield a detectable gamma-ray burst of known signature. None seen so far.

But it's PUB CONTINUATION TIME now!

Collisions in Space Theory is FLAWED

The "Cosmic Rays occurring in Space" theory is flawed. Particles created from cosmic rays that strike with the Earth travel at nearly the speed of light. If neutral micro black holes are created from cosmic ray impacts with Earth they would pass through Earth and into space adding to the dark matter (non-light emitting matter) in the universe. The LHC collides particles head on and some particles produced by the LHC will be slowed down enough to be captured by Earth.

CERN just simply isn't taking this into account. Instead, they're putting all of humanity at risk.Many reputable scientists agree that the risk of catastrophe is at least 50%. The day collisions begin, I recommend keeping your children home from school and reminding them how much you love them. This isn't looking good.

Alan is right

Alan is absolutely right, head-to-head direct particle collisions are extremely rare in space and we really don't know what happens for sure. Yet we're attempting to do it on our home planet. I say again, there is a huge risk that something can go horribly wrong.

You're right, head-on particle collisions in deep space ARE pretty rare, compared to the length of time humanity has lived.

Of course head-on particle collisions in deep space have only been going on for what, ~15 billion years? At much higher energy levels. So what are the chances of anything having gone wrong anywhere remotely near any place our solar system has ever gotten close?

Pretty damned close to 100%.

Some fairly simple energy considerations.

It doesn't matter if head-to-head collisions in space are extremely rare, because the collisions between some of the more energetic cosmic rays we've already seen and fairly mundane atmospheric nitrogen nuclei are still many orders of magnitude more powerful than what the LHC can manage by whacking two multi-TeV protons together.

The only reason anyone even bothers building supercolliders is so that energetic collisions can happen on demand in large numbers in controlled environments which happen to have elaborate sensors immediately nearby. Cosmic rays have been identified (type "Oh My God particle" into Google*) with kinetic energy comparable to that of a professionally pitched baseball; one little subatomic particle with a kinetic energy of tens of joules, or about eight or nine orders of magnitude beyond what the LHC can impart to a proton. None of these has destroyed the earth, despite standing what should, by all rights, be a far better chance than any of the protons the LHC will accelerate.

As for "right here on earth": The protons are travelling at a hair less than the speed of light, and doing so in such a direction that points through some relatively shallow part of the Earth's crust and into space, whereas a cosmic ray striking Earth with twenty joules of kinetic energy tends to aim through rather more of the planet and, despite the energy difference, is not going appreciably faster. Somehow, nothing more interesting has resulted from this than the occasional Cerenkov radiation event in the upper atmosphere.

Active galactic nuclei are producing particles more energetic than those of any accelerator mankind is likely to produce within the lifespan of the solar system, since the production of black holes of several billion solar masses like one might need to produce such particles will likely elude our manufacturing capabilities for the forseeable future. Yet, somehow, things which stand in the way of their jets are not turning into clouds of strangelets or black holes or whatever other nonsense. All that happens to them is that they get hit with a lot of intense radiation from the jet, on account of which I recommend against the wishes of any readers overly sensitive to gamma rays who plan to vacation to M87**.

Re collisions in space probability

I don't pretend to know the physics, but regarding this question about direct collisions in space happening and us not getting big bangs.

I'd assume that a few random direct hits in an area the size of the earth every second won't cause anything more than a very tiny explosion / mini blackhole or similar....nothing that we'd notice since if we did life wouldn't have gotten going. However if you send a concentrated beam of billions of particles towards each other then won't this likely increase the effect drastically and thus increase the chances of something more noticeable happening?

For the record - not against this LHC thing, just trying to put non-physics teacher logic to it.

"I don't pretend to know the physics, but regarding this question about direct collisions in space happening and us not getting big bangs."

Yes, but consider: we know that White Dwarfs and Neutron Stars exist. These balls of compressed matter absorb cosmic rays; if anything untoward would happen with reasonable probability, these stellar objects would quickly transform into Strange Stars or Black Holes, the more so as a microscopic Black Hole would have a hard time _not_ finding material in its immediate vicinity to hoover up; it could not traverse the star like a bird traverses a cloud. This is not being observed.

"If neutral micro black holes are created from cosmic ray impacts with Earth they would pass through Earth and into space adding to the dark matter (non-light emitting matter) in the universe."

Sorry but you are forgetting that the Earth is not the only object in the galaxy. Micro black holes would not pass so easily through a star, particularly a neutron star, and yet nobody has ever seen stars disappear and yet these are being hit by the same cosmic rays that hit the Earth.

"CERN just simply isn't taking this into account."

Yes we are - the argument regarding neutron stars was used in a recent LHC safety report conducted by non-CERN particle physicists. There is absolutely no scientific reason for any safety concern from Black Holes and if you doctorate were in physics you would know that.
