‘The physics community has never separated like this’: Row explodes on plans for the new major Hadron collision | Big hadron collision

Scientists develop plans to build the world’s largest machine in an area below the Swiss-French border. More than 30 billion dollars (£ 23 billion) will be spent to drill a 91 km circular tunnel in which subatomic particles will accelerate to the speed of light and break down. From the resulting nuclear ruins, scientists hope that they will find clues to help them understand the detailed structure of the universe.

It is an extraordinary ambitious project. However, it is also a controversial thing – many scientists are afraid of the machine, the future circular striking (FCC), for decades, financing for under -atomic physics for decades and can be caused by new promising ways.

Others argue that Mega-Collider is imposed on physicists without consulting the European Nuclear Research Organization CERN without consulting appropriately.

“I am surprised to see how they listed this concept,” I surprised to see how they listed this concept. Observer. “Things don’t have to work like this. The physics community needs to tell CERN what the next step should be, not the opposite.”

These arguments directed the magazine Nature This month, “a war continues for the future of particle physics”. He warned that many of the dozens of physicists analyzed their views, many of them criticized the proposed collision and could trigger the dangerous sections between the groups. As Prof Ruben Saakyan from London University College said to the magazine: “ [physics] The community has never been divided before. “

CERN says FCC offers scientists the chance to make a “unique discovery of space, time and matter. Since its establishment in 1954, the organization in Geneva has become a very challenging example of the effectiveness of international scientific cooperation, and has gained a reputation in producing world -leading research for decades.

Great Hadron Collider (LHC) – Currently, the world’s largest machine – in 2012 revealed the presence of Higgs particle. This was the first direct evidence that an area known as the Higgs area penetrated the universe and was responsible for giving various masses to different basic particles.

However, LHC is planned to be closed by 2040 and although it would provide greater information, many puzzles have not been solved about the structure of the universe. Among the permanent mysteries, its presence includes the nature of the dark matter, which is extracted from the influences of gravity on galaxies but unknown. Similarly, the existing observations cannot be explained by the existing observations.

In order to meet these problems, CERN proposed to build a new mega-coach, which will have a much stronger and much larger version of LHC. It would be built in two stages. First, to understand the critical roles in influencing other basic forces, HigGS particles would produce large numbers and would be around 2040 online. At that time, it would be reused after a few decades, so that he could hit the protons in large energies and provide new data about the universe. This version will start around 2070.

However, in unique energies recommended for FCC, acceleration technology is not available yet. It is assumed that it will be developed only in 40 years. Such an assumption worries some scientists and the fact that FCC will cost so much that it will lock scientists into a device that will monopolize funds for particle physics for decades.

Abramowicz, who was rejected as a “toy değiştiril, who may not be able to guarantee the holes existing in the current theories, said Abramowicz said,“ We ​​will stop the development of other technologies because there will be no money for them and years, ”he said.

Instead, the researchers have proved that linear accelerators to fire particles with flat lines have proved that the likelihood of cheaper, more flexible and more likely to achieve results may be more than a circular collision. This point was supported by the German accelerator center Deutsches Electronen-Synchrotron (Desy)-based researcher in Hamburg.

“There are other technologies on the horizon that can be used to accelerate particles such as protons without the need for large magnets or tunnels,” he said. “Plasma wave technology is one of them. The existing devices were small, but we could see that they were ready to use to run a great striking in 20 years.”

However, if he continued to FCC, he could lock funds for decades and dictate the aspect of particle physics in most of the century, and the list has been added.

“We will tell the next generations exactly what to do scientifically, and that’s why we need to ask ourselves today: Who will decide what our grandchildren should research and do not do research?”
