Gravitational waves fascinate me.
Somewhere at this very moment in a galaxy billions of light years away there are two ginormous black holes caught in the mighty tug of the other’s killer grip and forcing each to circle the other like passionate whirligigs. There’s so much mass concentrated in these two titans that the entire universe jiggles as these sparring black holes close the gap. As the laws of physics decree, the faster those black holes dance around each other the more gravitational waves they produce, emanating like ripples on a lake. Those gravitational ripples pull energy away from this dancing duo and forces them into an ever tighter embrace. Sooner or later so much gravitational energy is lost that it pushes these two behemoths so close together that they literally smack into each other in a mighty “BOOM!!!” that spews gravitational waves all over the heavens and leaving behind an even larger black hole as the final victor. Eventually those gravitational ripples make their way to our humble little world which we can pick up with the aid of specially designed detectors. Pretty wild stuff if you ask me. I’m positive that’s what made me flinch.
