有个巨大的，差不多 1000 倍于地球面积的物体，正阻挡着来自遥远恒星 KIC 8462852 发出的光。没有人确切知道那是什么东西。天文学家 Tabetha Boyajian 讨论了这个巨大的、异常的天体可能是什么。一位同行提了一个不太寻常的建议：这有没有可能是外星人建造的巨大的超级建筑呢？如此非同寻常的想法需要非同寻常的证据来证实。在本次演讲中，Boyajian 讲述了作为科学家，面对未知如何搜寻并且检验假说的故事。

宇宙中最诡异的恒星

A distant star, KIC 8462852, baffled astronomers when its brightness dipped by over 20 percent, hinting at something massive—possibly 1,000 times Earth's area—blocking its light. Citizen scientists, not computers, first spotted the star’s strange behavior in the Kepler data, igniting a global scientific puzzle. Natural explanations, from comets to planetary collisions, fell short, while speculation reached as far as alien megastructures. The ongoing investigation unites professionals and amateurs, highlighting the power of human curiosity in the face of the unknown.
