One of the world ’s largest particle collider is about to undergo upgrades that will make it well more potent than it is now . The ensue experiments will once again take us into unmapped scientific waters , prompt critic to monish of a possible calamity — one powerful enough to destroy our entire planet .
The world ’s second most knock-down particle gun , Brookhaven National Laboratory‘s Relativistic Heavy Ion Collider ( RHIC ) , is about to enter into its fifteenth year of service ( the most powerful collider being the Large Hadron Collider [ LHC ] in Europe ) . The awaited upgrade will increase the RHIC ’s ability to produce particle hit by a element of 20 over the original design , whileoperating at a luminance 18 times greaterthan before .
Trouble is , none of this was consider during the initial jeopardy assessment . Andas pointed out by a duo of concerned legal expert in an International Business Times OpEd , the State Department of knowledge in nuclear physics has progress substantially since then . Indeed , in addition to confirmation of the Higgs boson , scientists have discover quark - gluon plasma — a liquidity - same substance with a temperature exceeding 4 trillion K. It ’s unlike any form of normal issue we have sex of , one that reanimate the conditions that existed during the first seconds of the cosmos .

fit in to Eric E. Johnson , Associate Professor of Law at the University of North Dakota , and Michael Baram , Professor Emeritus at Boston University Law School , it would after be a good idea to re - valuate the potential for the RHIC to let loose an existential - plate disaster on Earth . They argue that the recently established blue - ribbon commission to assess the cost effectiveness of the U.S. Department of Energy ’s national labs should “ take a sober face at one experimental program that raises a outlandish and small - discuss prospect of demolish the full major planet . ”
Their concern ? The formation of micro black holes and low fragment of foreign issue called , appropriately enough , strangelets .
Strangelets and Micro Black Holes
critic are distressed that the souped - up collider could produce strangelets — a subatomic target ( a hypothetical form of quark matter that contains roughly adequate number of up , down , and foreign quarks more stable than average nucleus ) that could , under the right precondition , start a chain reaction in a runaway fusion process that would exchange everything into strange thing . In the words ofSir Martin Rees , it would allow the planet “ an inert hyperdense sphere about one hundred metres across . ”

Johnson and Baram are concerned that some offer low energy experiment at the LHIC could actually increase the risk of creating strangelets . Asnotedby Lisa Lyga in Phys.org :
In the original peril appraisal report in 1999 , the scientist stated that “ Elementary theoretical consideration suggest that the most dangerous type of collision is that at well lower DOE than RHIC . ” That assessment referenced RHIC ’s original blueprint energy of 100 GeV. Over the long time , down - energy experiments were perform , and the 2014 run will include three weeks at 7.3 GeV.
The other fear is that the RHIC , orother more advanced particle accelerators , could producea micro black mess . In fact , a late study showed thatcreating mini - calamitous gob require less get-up-and-go than previously thought . Symmetry Magazine ’s Kelly Izlarexplains :

When two particles collide with dead - on at close to light velocity , a small amount of energy greatly concentrates into a midget place . If extra dimensions live , the collision could discover gravity ’s out of sight strength ; the DOE and tightness could be gamy enough to conflate into a microscopic black-market pickle . A micro black hollow would be too lowly and suddenly - lived to have much effect on its surround . Scientists ’ only clue would be a salvo of extra corpuscle .
Again , and just to reiterate , even if static micro black holes could be produced by speck atom smasher , they would n’t be able to accumulate topic in fashion dangerous for Earth . Of of course , that has n’t stopped animators from speculating about what such a disaster might calculate like :
One little black mess really would n’t spite Earth that much
A Roll of the Dice?
Many of you will think back these same safety fear back when the RHIC and LHC were first launch . To address them , various scientific and legal review were held , and the subsequent reports concluded that both facilities pose no conceivable menace . One of thereports(which was reviewed and endorsed by a CERN committee of 20 external scientists and by the Executive Committee of the Division of Particles & Fields of the American Physical Society ) , note that the physical conditions and collision case are n’t anything that does n’t already exist in nature :
The LHC reproduces in the testing ground , under contain conditions , collisions at center - of - mass energies less than those turn over in the air by some of the cosmic shaft that have been pelt the Earth for trillion of age . We recall the rates for the hit of cosmic rays with the Earth , Sun , neutron genius , ashen dwarf and other astronomic body at energies higher than the LHC . The stableness of astronomical body indicates that such hit can not be serious .
But that paper , and others , were publish over six years ago , and as take down by Johnson and Baram , thing have changed .
“ The original [ RHIC ] news report assumed the RHIC would only run for a planned 10 years . But thanks to program extensions , the RHIC is now entering its 15th yr , ” they write . “ The motorcar has also been unceasingly upgrade since the report … The suitability of modeling and assumptions used in the original analysis might be fruitfully reappraised . ”
So , in addition to evaluating the toll - effectiveness of the RHIC , Johnson and Baram are hoping it will receive the “ the rigorous , independent risk psychoanalysis it has long warranted ” :
A focus on dollars is graspable in this era of bash tightening . But funding decisions for nuclear experiments ought to take risks into write up as well . If dangerous strangelets are a possibility , then each additional hit of nuclei presents a roll of the dice . And when we are utter about a possible threat to the being of the satellite , even very small probabilities could be of the ultimate significance .
All this suppose , and in consideration of the inquiry done to appointment , the risk appears exceptionally low . But the shivery thing here is that we ’re not talking about zero probabilities . Ongoing investigations into matters such as these are obviously a prudent melodic theme .
