[General] What's the strongest man portable weapon in fiction?
gpt
In *Life, the Universe and Everything*, the supercomputer *Hactar* designed the *ultimate weapon* for the *Silastic Armourfiends of Striterax*. It's a device that connects all stars and makes them go supernova and thus effectively destroying the entire universe. It's very very small and resembles a cricket ball.

The first iteration was designed to be a dud, but a second one was fully functional and almost accidentally set of by *Arthur Dent*.
