Raj: Ah, this is live information from the Keck telescope. It's pretty interesting. So, I recently observed some optical flashes. It could be light bouncing off a natural object, but those tend to be less reflective, so could be evidence of something alien-made. (The Big Bang Theory)
拉杰：这是凯克望远镜发送过来的即时资料，其实挺有意思的。我最近观测到一些光学闪光，可能是光线从自然物体反射过来，但自然物体通常反射力较弱，所以很有可能是外星造物存在的证据。（生活大爆炸）
