上周三，美联储宣布维持每月850亿美元的债券购买计划不变。美联储的这一决定是根据国家原子钟于下午2点准时在华盛顿发布。消息从华盛顿传到芝加哥交易所需要7毫秒。然而，下午2点过后2到3毫秒，数十亿美元交易订单已经发出，从而能利用这一信息对市场产生影响的时间差获取巨额利润。美联储的成员一直呆在一个安全房间内，不得与外界沟通，直到2点过后才获准离开。是有人提前泄露了信息？还是有人发明了中微子通信技术？利用光缆，从华盛顿到芝加哥信息传输需要大约7毫秒；两地的直接距离是960公里，如果利用中微子通信穿越两地之间的一切障碍，那么所需时间大约为3毫秒。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
