宇宙弦(Cosmic string)是假设性的、理论上可能存在的时空。假设宇宙弦是成立的,在不同时空产生第一阶段变化时,在域边界取得了的两个地区之间的那个“弦”。 这有点类似于界限之间形成晶体颗粒,晶体颗粒在凝固的液体,或裂缝形成时,水冻结成冰(ρ<水)。在我们的宇宙,如相变化可能发生在早期作为宇宙的形成。它应出现于宇宙极早期时间,在大爆炸之初,0秒到1秒之间的极短瞬间。
宇宙弦还会产生无与伦比的至强引力波。
Cosmic strings would also create incredible gravitational waves, stronger than any other known source.
宇宙弦与此类似,它是时空上狭长的瑕疵带。
This is similar to the objects called cosmic strings, which are extremely thin and extremely long defects in the shape of space-time.
有人认为宇宙弦长得离谱,最长可与上千银河比肩。
Cosmic strings are thought to be incredibly long, up to the order of the sizes of thousands of galaxies.
