The safety of high energy particle collisions was a topic of widespread discussion and topical interest during the time when the Relativistic Heavy Ion Collider (RHIC) and later the Large Hadron Collider (LHC)—currently the world's largest and most powerful particle accelerator—were being constructed and commissioned. Concerns arose that such high energy experiments—designed to produce novel particles and forms of matter—had the potential to create harmful states of matter or even doomsday scenarios. Claims escalated as commissioning of the LHC drew closer, around 2008–2010. The claimed dangers included the production of stable micro black holes and the creation of hypothetical particles called strangelets, and these questions were explored in the media, on the Internet and at times throug

rdfs:comment	Некоторые специалисты, а также простые граждане, поднимают вопросы по безопасности Большого адронного коллайдера. Эти вопросы имеют заметный резонанс в средствах массовой информации. (ru) 高能粒子对撞实验的安全性问题在相对论性重离子对撞机（RHIC）以及大型强子对撞机（LHC）建设和承担任务期间受到了广泛关注和议论。公众担心用于制造新的粒子和物质形态的高能可能会产生有害的物质状态甚至导致全球灾难危机。在LHC即将投入运行的2008年至2010年间，有关其安全性的争论更为激烈。其中涉及到的风险包括产生稳定的微型黑洞或是制造出假定存在的奇异夸克团。这些问题受到了传统媒体、互联网以至法院的关切。为了回应对于LHC的担忧，欧洲核子研究中心（CERN）委托了一批独立科学家来评估风险。在2003年发表的报告中，他们总结道，目前的粒子实验，例如RHIC和LHC中的粒子碰撞，不会产生任何威胁。CERN之后又委托了一批隶属于中心但不参与LHC项目的物理学家做了另一次评估。在2008年发表的报告中，他们基于对于安全性的新的研究结果重申了LHC对撞实验的安全性。这份报告得到了20位CERN外部科学家组成的委员会和美国物理学会粒子和场部执行委员会的审核和认可，随后在受同行评审的刊物《》中发表。发行这一刊物的英国物理学会也认可报告的结论。报告排除了大型强子对撞机导致全球灾难危机的可能性，并表示LHC、RHIC以及其他实验中的物理情形和碰撞事件在宇宙中自发而定期地发生，而没有导致有害的后果。比如地球上观测到的所具有的能量就比人造粒子对撞高得多。 (zh) The safety of high energy particle collisions was a topic of widespread discussion and topical interest during the time when the Relativistic Heavy Ion Collider (RHIC) and later the Large Hadron Collider (LHC)—currently the world's largest and most powerful particle accelerator—were being constructed and commissioned.

Les dangers supposés des collisions de particules au LHC qui sont planifiées à partir de l'automne 2009, sont des scénarios d'apocalypse impliquant la création de trous noirs et de particules hypothétiques nommées strangelets.
