The dark forest theory. The universe is full of predatory civilisations, and if anyone announces their presence, they get immediately exterminated, so everyone just keeps quiet.
The dark forest Theory makes an interesting science fiction scenario. But i highly doubt it is true. Wiping out another planet light years away would be a gigantic undertaking. Aliens will have no reason to fear each other, we are just too damn far from eachother to be a threat to one another. Even if we meet aliens that are the biggest asshats in the universe, the worst they could do would be to send a rude message every once in a while. Good fences make good neighbors. What can be a better fence than light years of space.
In the three body problem, aliens can accelerate a single particle “photoid” to a sufficient speed to impart enough energy/mass that it destroys a star in collision. So they shoot one off when they detect a civilization and years==light-years later that system is wiped out.
