Observational tests of wormholes

本研究的目的是寻找虫洞观测检验的方法。直到最近，虫洞都是广义相对论引入的纯粹假设对象。对丰度没有限制。我们举办了两次研讨会，讨论虫洞测试的方法和意义。已经取得了惊人的进展。已经提出了几种新方法。然后进行了三次搜索虫洞的尝试。到目前为止，还没有找到候选人。对厘米大小的虫洞和银河尺度的虫洞施加了限制。对行星大小的虫洞已经有了初步的限制。这些结果表明虫洞并不像恒星那样丰富。对虫洞的稳定性进行了研究。这些研究表明虫洞是不稳定的，很难在宇宙年龄内存活。

The purpose of this research is to find methods of observational tests of wormholes. Until recently, wormholes are purely hypothetical objects introduced by the General Theory of Relativity. There was no restriction on the abundance. We have held two workshops to discuss the methods and meaning of the tests of wormholes. There have been amazing progress. Several new methods have been proposed. Then three attempts have been done to search wormholes. Until now, no candidate has been found. The limits have been imposed on the cm size wormholes and galactic scale wormholes. A preliminary limit has been imposed on the planet size wormhole. These results implies wormholes are not abundant as stars. There were several activities on the stabilities of wormholes. These studies show the wormholes are unstable and hard to survive cosmological age.
