什么是反物质?反物质就是指物理学家根据反粒子理论提出的由反粒子组成的物质.物质都是由基本粒子组成的.1897年,英国科学家汤姆生发现了第一个基本粒子——电子,以后,科学家们陆续发现了质子、中子、各种介子和超子,现在基本粒子已多到三百余种.而所谓反粒子,则是指电荷数与原粒子相反的粒子.1928年,英国物理学家狄拉克创见性地预言了电子的反粒子——正电子的存在,1932年,美国科学家卡·达·安德逊在研究宇宙
What is anti-matter? Anti-matter refers to the physicist’s anti-particle theory based on the composition of the anti-particle material. The material is composed of basic particles. In 1897, the British scientist Thomson discovered the first basic particle - electron, Later, scientists discovered protons, neutrons, various mesons, and supertrons. Now, there are more than three hundred kinds of elementary particles. The so-called antiparticles refer to particles whose charge number is opposite to that of the original particles. 1928 British physicist Dirac creatively predicted the anti-particles of electrons - the existence of positrons. In 1932, American scientist Ka Da Anderson studied the universe.
