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.

本研究的目的是寻找虫洞观测试验的方法。直到最近，虫洞都是由广义相对论引入的纯粹的假设对象。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。已经提出了几种新的方法。然后，三次尝试已经完成了搜索虫洞。到目前为止，还没有发现任何候选者，对厘米级虫洞和星系级虫洞的研究受到了限制。一个初步的限制已经强加在行星大小的虫洞。这些结果意味着虫洞并不像恒星那样丰富。关于虫洞的稳定性有几个活动。这些研究表明，虫洞是不稳定的，很难生存的宇宙年龄。
