The Earth will not be destroyed

Will the black hole swallow the earth? Forget it and continue to pay your mortgage, of course if you have land to pay taxes.

A new Large Hadron Collider (LHC) molecular accelerator, expected to go into operation this fall on the outskirts of Geneva, does not bring any threat to the earth or the universe. That is information from Cern's safety report, the manufacturer of this accelerator. The report was approved by the board of directors of the European Nuclear Research Organization, which built the accelerator.

The safety assessment team consisted of five physicists who wrote in their report that: 'There is no basis to worry about the consequences of new elements or forms that can be manufactured by LHC.' Any activity of the accelerator has happened in nature many times.

Physicists who worked anonymously for a year and a half are John Ellis, Michelangelo Mangano, Gian Giudice and Urs Wiedemann of Cern, along with Igor Tkachev of Moscow's Research Institute. In a press conference, Cern director Robert Aymar said: 'With the report, the laboratory has completed all the environmental and safety tests required to ensure its robust operation. This interesting research device '.

They showed the progress of the machine being pushed up to the maximum. It was designed to accelerate Proton, the basic unit of matter, to the energy of 7 trillion Electrons and then smash them together to create primitive fireballs, a small version of the explosion. forming the Big Bang universe. Physicists will collect debris from those fireballs to find the forces, particles, or even new laws of nature that can occur in 1/100 million seconds.

Some critics claim that Cern has ignored or underestimated the risk that the accelerator could create a black hole that swallowed the earth, or that it could create dangerous particles.

However, the safety team has shown that cosmic rays also create energy collisions equivalent to the earth and other objects in space many times . They wrote: 'This means that nature has done about 1031 LHC experimental programs since the universe was formed' . But stars and galaxies still exist.

The new report is an update and extension of a 2003 report, focusing on black hole issues. They can be created according to some variations of speculative string theory . Can a black hole swallow the earth? These theories predict that black holes will disintegrate very quickly. But if a stable black hole is somehow created, it is very likely that it is produced from cosmic ray conflict.

The report focuses primarily on a 96-page analysis of Steven B. Giddings of the University of California, Santa Barbara, and Dr. Mangano, which will be available on the next physics section. In that paper, Dr. Giddings and Dr. Mangano concluded: 'Prudent arguments are based on detailed observations as well as the best available scientific knowledge, including reliable astronomical data, which leads to the multidimensional conclusion that there is no risk from black holes'.

The difference between the two ways of creating black holes is that black holes created from cosmic rays have a speed close to the speed of light, passing straight through the earth without leaving any impact; while the black hole created by conflict is related to the earth and can be captured. However, if black holes created from cosmic rays actually exist, physicists say dense cosmic ash such as neutron stars or white dwarfs can hold them and are swallowed up. But that does not happen and the above objects continue to exist.

This report is reviewed and approved by a scientific council outside Cern. Finally, after 14 years with an investment of 8 billion dollars, the future of physics has come close.

Cern's engineers are in the process of cooling superconducting magnets, powering the protons around their 17-mile path, down to about 3 degrees F above absolute zero. They are doing it on schedule, and said they will start circulating protons in the accelerator in August, then start overclocking them a few months later.

Since the engineers have not completed the "training" of the current-carrying magnets needed to push protons to the highest energy, the original plan was to pulse each proton by 5 million electron volts, five times the The amount of physicists achieved before.

Traditionally in winter Cern will close for a while, the magnet will be trained to the highest energy. The spring to the accelerator will be activated again with 14 million pulses of momentum. Then physicists will be able to breathe.
