Atomic accelerator dating
The vacuum, Rees states, has in it “all the forces and particles that govern the physical world.” And he adds, it’s possible that the vacuum we can observe is in reality “fragile and unstable.” What means is that when a collider such as CERN’s LHC creates unimaginably concentrated energy by smashing particles together, Rees says, it can create a “phase transition” which would tear asunder the fabric of space,” which cause a cosmic calamity not just a terrestrial one.” The possibility is that quarks would reassemble themselves into compressed objects called strangelets. However under some hypotheses a strangelet could, by contagion, convert anything else it encounters into a new form of matter, transforming the entire earth in a hyperdense sphere about one hundred meters across –the size of a soccer field.
The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture.
Standing by the new Linac 4 machine, which cost 93 million Swiss francs ( million) and took 10 years to build, project leader Maurizio Vretenar said CERN had miniaturized the technology and saw many potential uses.
“It’s a brave new world of applications,” he told Reuters in Linac 4’s tunnel 12 meters under Geneva.
CERN has already built a version to treat tumors with particle beams and licensed the patent to ADAM, a CERN spin-off owned by Advanced Oncotherapy.
Another medical use is to create isotopes for diagnosing cancers.
Other museums don’t have the same luxury, and may not want to send their artworks away for analysis.
The inside of a prototype of a drift tube of the new linear accelerator Linac 4, the newest accelerator acquisition since the Large Hadron Collider (LHC), which is due to feed the CERN accelerator complex with particle beams of higher energy, is pictured during its inauguration at the European Organization for Nuclear Research (CERN) in Meyrin near Geneva, Switzerland, May 9, 2017.
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.
The method was developed in the late 1940s at the University of Chicago by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960.
Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons.
The experiments during 2018 at world-wide highest energy with the ALICE detector at the Large Hadron Collider (LHC) at the research center CERN produce matter where particles and anti-particles coexist, with very high accuracy, in equal amounts, similar to the conditions in the early universe.
