Greetings everyone, I have a question that bothers me. What if two objects are traveling at 0.6C at opposite directions? Do no forces (gravitational mainly) apply to them at all? Is gravity only traveling at the speed of light or could this be challenged? It just seems to me weird that the gravity of objects 1 lightyear away take a year to occur while in the meantime one of the objects might have been destroyed. If these objects travel at such speed and direction the gravitational force will never reach them, thus this would render the law of universal gravitation false. I am no physics guy so if possible try to use something less academic. Thanks a lot for any answers.
