在欧洲核子研究所(CERN)的实验室里,每10分钟有10亿颗反质子,以1/10光速飕飕的从一个环形加速器中飞奔出来。可是要想合成一个最简单的反原子却很不容易。1996年他们制造出9颗反氢原子,一下成为该年度的科技大新闻。新闻界为何对此给予如此高的评价?也许这联系到一个深奥的原因:反物质世界是否存在? 反物质世界并不像听起来那样古怪,其实大自然中每个粒子,皆伴有一个反粒子,它的性质刚好与该粒子相反。如电子带一负电荷,反电子则具正电荷。两者间的关系的确可谓古怪,它们一旦相碰
In the CERN laboratories, there are 1 billion anti-protons every 10 minutes, running out of a circular accelerator at 1/10 speed of light. However, it is not easy to synthesize one of the simplest anti-atoms. In 1996 they created nine anti-hydrogen atoms, and then became the science and technology news of the year. Why does the press give such a high evaluation? Perhaps it is related to a profound reason: the existence of an anti-material world? The anti-material world is not as weird as it sounds. In fact, every particle in nature is accompanied by an anti-particle, Its nature is exactly the opposite of the particle. If the electronic belt with a negative charge, the anti-electronic positive charge. The relationship between the two indeed strange, once they meet
