In a rocket a person can burst like a bubble, or solidify completely, or boil, or explode in a fountain of blood so quickly he doesn't have time to shout out, and then only his bones will be clattering against the metal, and they'll go on circling in Newtonian orbit with an Einsteinian adjustment, our rattles of progress!
