发帖数: 1166 | 9 科学家首次在实验室制造出传导磁场的“虫洞”时空隧道，因此提示宇宙的三维空间之
外还存在另外的空间。
据“每日科学”（science daily）网站9月3日报导，西班牙巴塞罗那自治大学（
Universitat Autònoma de Barcelona）的科学家在实验室内，使用超材料和超导界面
建立了磁场传送隧道。他们检测到，在产生磁场的磁力源远端，出现了不可能在自然界
中单独存在的磁单极子。
报导说，这一实验结果让科学家感到很惊讶。其结果只能解释为，磁场的一个磁极被传
送到另外的部位，但是传送过程与途径是无法被检测出来的，这个隐形的传送过程与途
径就是超出常规三维空间的另外空间。
首席研究员阿尔瓦‧桑切斯（àlvar Sánchez）解释道，磁场虫洞是引力虫洞的
模拟形式，因为磁场虫洞“改变了空间的拓扑性质（topology），其条件是磁力清除空
间中的内区（inner region）。”
报导说，实验结果也提示，人们能够更好地利用磁场，比如在医疗中的核磁共振（MRI
）领域，可以实现远程核磁共振检查而不必让病人进入或靠近检测仪器，因此让病人感
到更舒适。

An excerpt from: Occult Ether Physics
by William R. Lyne
From: Don Allen

According to Tesla's lecture prepared for the Institute of Immigrant Welfare
(May. 12, 1938), his "Dynamic Theory of Gravity" was one of two far
reaching discoveries, which he "...worked out in all details", in the years
1893 and 1894. The 1938 lecture was less than five years before his death.
