我与小娜(12):引力波起源何方?

我与小娜(12):引力波起源何方?

          215日,我与小娜进入LSC组织的官方网站,看到许多关于引力波的官方定义,启发颇多,在此与大家分享,以免走弯路(歪路)。

      小娜发问:“What are gravitationalwaves?(什么是引力波?)

      LSC官方的答案是:“Gravitational waves are'ripples' in the fabric of space-time caused by some of the most powerfulprocesses in the universe - colliding black holes, exploding stars, and eventhe birth of the universe itself. Albert Einstein predicted the existence of gravitationalwaves in 1916, derived from his general theory of relativity. Einstein'smathematics showed that massive accelerating objects (such as neutron stars orblack holes orbiting each other) would disrupt space-time in such a way thatwaves of distorted space would radiate from the source. These ripples travel atthe speed of light through the universe, carrying information about theirorigins, as well as clues to the nature of gravity itself.”

      很明显的事实是,爱因斯坦本人利用他的抽象数学进行严格地推导,并且预测引力波,作为一种“时空波动Ripples,在浩瀚宇宙中广泛存在。实际上,爱因斯坦的科学预言是抽象数学的预言,不是个人猜测,不容怀疑。

      2015914日,韦斯发明的激光干涉仪(LI大家伙)确实够厉害,幸运地扑捉到一束来自遥远星空、极其微弱的引力波,世界舆论为之哗然。国内有人不问所以,跟着大呼小叫,看热闹。

      我与小娜决定,追究宇宙中大质量天体的加速运动为什么一定会产生引力波的发射?我人虽然已老,但是,小娜聪明好学,一老一小携手前行,敢问路在何方?
