"Collapsing Cosmoses" is a very short (and apparently humorous) science fiction story by the late American authors H. P. Lovecraft and R. H. Barlow. Despite being billed as a short story, a more accurate description might be a fragment of an uncompleted work. It was published the year after Lovecraft's death by the fanzine Leaves.
Synopsis[]
Alien beings begin to muster their forces for war after receiving notice that a fleet of unidentified ships are converging on their area of the cosmos.
