引力弦。我们看到一个吗?

Gravitational strings. Do we see one?

S. V. Krasnikov

摘要:

我提出了一类被称为引力弦(GS)的物体,因为它们与传统的宇宙弦相似:尽管前者只是平坦时空中的奇点,但这两种类型都是同样“现实的”,它们可能扮演同样重要的宇宙学角色,它们的透镜性质是相似的。我认为,神秘的对象CSL-1是一个证据,有利于GS的存在。

英文摘要:

I present a class of objects called gravitational strings (GS) for their similarity to the conventional cosmic strings: even though the former are just singularities in flat spacetime, both varieties are equally "realistic", they may play equally important cosmological rôle and their lensing properties are akin. I argue that the enigmatic object CSL-1 is an evidence in favor of the existence of GS.
