Correlation Between Particle Universe And The Origin Of Life

The Standard Model of particle physics summarizes the most basic structure of matter,including three Fundamental interaction of strong,weak and electromagnetic,as well as the theoretical mechanism of electric weak symmetry breaking of mass origin.The discovery of Higgs Boson in 2012 ended the search for Elementary particle in the Standard Model.The theoretical predictions of the standard model of particle physics are highly consistent with the experimental results.So far,the experimental results of electromagnetic,weak,and strong interaction have met the predictions of this theory.Although there are some problems,such as not including gravity,unable to explain the mass of neutrinos,and lack of dark matter candidates,we cannot deny its success.At the same time,astrophysics has also made great achievements,which strongly support the Big Bang theory through the accurate measurement of the Big Bang nucleosynthesis and microwave background radiation.According to the theory of the Big Bang,in the early days of the universe,the temperature and energy were extremely high,and the matter was in the state of particles and radiation,which also made particle physics closely combined with Cosmology,forming multiple frontier interdisciplinary disciplines such as particle Cosmology,nuclear astrophysics,Astrobiology,etc.Astrobiology focuses on origin of life and other issues.It is a newly developed interdisciplinary involving physics,astronomy,biology and other disciplines,and there is little research in China.Life is composed of material particles,and origin of life originates from material particles.Life is gradually born in the process of the evolution of the universe,and evolves or disappears due to the changes in the environment of the universe.Therefore,the exploration of the origin of life is inseparable from the research of particles and the universe.This thesis investigates the frontier progress of particle physics,cosmology and origin of life,tries to explores the relationship between particle universe and the origin of life,link particle cosmology and Astrobiology,and thoroughly explores the origin of life in several stages.In this thesis,the standard model of particle physics and the big bang model of the universe are first described,and the physical relationship between particles,the universe and life matter is revealed in the scale mass picture of everything.In Chapter 2,the origin of the positive matter world is mainly discussed,including the CPT symmetry in physics,the state of positive and negative matter symmetry in the early universe,and the mechanism of the formation of positive and negative matter asymmetry.This mechanism may have led to a far greater proportion of positive matter than antimatter in the current universe.The third chapter mainly discusses the elements of life and the origin of life.The Big Bang nuclear synthesis produced the early light elements of the universe,mainly composed of 75% hydrogen,25% helium,and a small amount of lithium.The light elements gradually generate heavier elements through the Nuclear reaction inside the star,and then combine carbon,hydrogen,oxygen,nitrogen,phosphorus,sulfur and other elements into organic matter,and gradually give birth to the earliest life.The fourth chapter talks about the possible connection between dark matter and the extinction of dinosaurs.Astronomical observations have found that in addition to ordinary matter,there are invisible dark matter and dark energy.Dark matter accounts for over80% of the total amount of matter in the universe,and the distribution of dark matter in the Milky Way may have a significant impact on the motion of related celestial bodies within the solar system.Through the exploration of meteorite craters,researchers found that there is a periodicity of about 30 to 35 million years for asteroids to collide with Earth.To explain this periodicity,scientists believe that there is also a thin disk of dark matter in the middle of our Milky Way disk.When the solar system moves up and down,it is subject to the dual gravitational effects of the Silver River disk and the dark matter disk.Ice bodies in the Oort cloud are disturbed and enter their orbits towards Earth.One of the asteroids crashed into Earth 65 million years ago,causing the extinction of 75% of species,including dinosaurs.At the end,a summary and outlook were given for the thesis.
