[Marvel Universe 616] What could stop Galactus?

At a certain point, it would seem as though the various civilizations would say "Enough of this bullshit!" and try to kill or contain Galactus. So, what would work?

Beta Ray Bill almost killed Galactus by finding out where he was going to feed and destroying the planet before he got there. So that's one way.

Reed Richards developed an anti-Galactus mecha suit that costs a billion dollars a second to run. That may work.

Doctor Doom stole his powers.

Aegis and Tenebrous beat the snot out of him.

Thanos once blasted Galactus so hard he went flying and his helmet shattered. It didn't come close to killing him, but he was not a happy camper afterwards.
