Introduction ). What are the mysteries of the origins of the universe in addition to the world's largest machine? The following information is disclosed on the site of the European Nuclear Research Center.

Over the past few decades, physicists have been deepening their understanding of the basic particles that constitute the universe and their interactions in detail. Deeper understanding makes the "Standard Model" of particle physics more plump, but there are still gaps in this model, so that we cannot draw a complete picture. In order to help scientists reveal these key unsolved mysteries in particle physics, a large amount of experimental data is required, and the large-scale Hadron ordinator will assume the role of a "data provider, this is also a very important step. The large-scale Hadron ordinator can accelerate the two beam to an unprecedented state of energy before a collision. The impact at this time may bring unexpected results, which is definitely unimaginable to anyone.

Newton's unfinished work-What is quality?

What is the origin of quality? Why are tiny particles having quality while other particles having no such "treatment "? Scientists have not yet found a definite answer to these questions. The most likely explanation seems to be found on the Hebrew boss. The Hebrew boss is the last undiscovered particle in the particle physics theory of the standard model. Its existence is the cornerstone of the entire standard model. As early as 1964, the Scottish physicist Peter Higgs predicted the existence of such particles for the first time, but scientists have not yet seen it.

Atlas and CMS experiments will actively look for signs of this elusive particle presence.

An "invisible" question -- what makes up 96% of the universe?

Everything we see in the universe-from small ant to a huge galaxy-is made up of ordinary particles. These particles are collectively referred to as matter, and they constitute a universe of 4%. The rest is believed to be composed of dark matter and dark energy, making it hard to detect and study them. Studying the properties of dark matter and dark energy is one of the greatest challenges facing particle physics and cosmology today.

Atlas and CMS experiments will look for super symmetric particles to validate a hypothesis related to dark matter composition.

Nature preferences-why can't we find antimatter?

We live in a world made up of things. Everything in the universe, including us, is made up of things. Antimatter is like a twin brother of matter, but it carries the opposite charge. When the universe was born, the Big Bang produced the same amount of material and antimatter. However, once the twins meet, they will "Get together" and eventually convert them into energy. Somehow, a small amount of material survived and formed the universe in which we live now, while its twin brother antimatter almost disappeared without a trace. Why can't nature treat this pair of twins equally?

The LHCb experiment will look for differences between things and antithings to help explain why nature is so biased. Previous experiments have observed some differences between the two, but so far research has found that it is not enough to explain why the number of material and dark matter in the universe shows a significant imbalance.

The secret of the "big bang"-what is the state of matter in the first second after the birth of the universe?

The material that makes up everything in the universe is believed to have come from a series of dense and hot basic particles. Now, ordinary substances in the universe are composed of atoms, and the atoms have a nucleus consisting of a proton and a neutron. the proton and neutron are formed by other particles that are called "gluon. This kind of constraint is very powerful, but in the first Universe, due to the extremely high temperature and great energy, it is difficult for the gluon to combine the quark. That is to say, this constraint seems to be formed in the first few microseconds after the "big bang". At this time, the universe has a very hot and dense mixture composed of quark and gluon, this is what we call the "quark-gluon plasma ".

Alice's experiment will use the large-scale Hadron orlinder to simulate the original Cosmic form after the Big Bang to analyze the properties of the quark-rubber plasma.

The hidden world-does the extra dimension of space actually exist?

According to Einstein's general theory of relativity, the three-dimensional space for human survival and the timeline constitute the so-called four-dimensional space. Later theories suggested that there may be spaces with hidden dimensions. The string theory implies that additional spatial dimensions have not yet been observed by humans, and they appear under high energy conditions. Based on this speculation, scientists will carefully analyze the data obtained by all detectors to find signs of extra dimensions.
