Human interest in the possibility of other worlds in the Universe has existed for over two millennia. In recent centuries, this question has been translated into the following terms: Are there planetary systems linked to stars other than the Sun? Developments in astronomical instrumentation have transformed this philosophical dream into a new, vibrant chapter in astronomy. This article describes my journey that started over 40 years ago with the exploration of the dynamics of our Galaxy, that brought astonishing scientific progress to which my collaborators and I have contributed, and eventually led to the amazing discovery of the plurality of worlds.

 多重世界


人类对宇宙中其他世界的可能性的兴趣已经存在了两千年多了。近几个世纪以来，这个问题已被转化为以下术语：是否存在与太阳以外的恒星相关的行星系统？天文仪器的发展将这一哲学梦想转变为天文学充满活力的新篇章。本文描述了我从 40 多年前开始探索银河系动力学的旅程，我和我的合作者为这一过程做出了贡献，带来了惊人的科学进步，并最终导致了多重世界的惊人发现。
