Specifically, I am wondering if the stretching that a gravitational wave does to you as it passes through you, if the stretching was big enough (say half a meter), could it rip you apart, or does it not work that way? I know that gravitational waves that go through Earth do not get this big, they only increase the distance between your head and your feet by a very small amount, but supposing that the amount was much much larger, would it separate your head from your feet, tearing you apart in your midsection? Or would you not even notice, as perhaps the bonds between atoms stay intact, even though spacetime is doing weird stuff? I suppose that if you die from spaghettification by falling into a black hole, then extreme gravitaiton waves will tear you apart too... ?? Further, I read this black hole merger that LIGO detected released the equivalent of three solar masses worth of energy as gravitational waves in about half a second? Assuming someone was close by, in a nearby spaceship, when that happened - what would happen to the person? Is there much radiation emitted that would fry them? When you're that close to three suns worth of matter becoming energy as gravitational waves, what happens to you in terms of the gravitation waves passing through you? Would a nearby planet be torn apart?
