Well, I heard a question from Roula and I will answer it. My favorite SciFi is Ender’s Game by Orison Scott Card. It is about a war against an alien species known as the Formic or the Buggers. Ender is the kid who commands the attack fleet in the Third Formic War and defeats the aliens.
Here’s my idea of the day. I believe humans already have the technology and resources to build a starship. Not with those fancy antimatter ships, but just a large spaceship that runs on nuclear power. It could be launched in pieces into space, built in space, then sent close to Jupiter to gravitationally assist the spacecraft, then it would start exploding nuclear weapons behind it so it would get shot to its destination.
