The Asteromorphs are a future human species that appear in the speculative fiction work All Tomorrows. They are the descendants of the spacer faction that spread through the galaxy after disappearance of the Qu in gigantic hollowed-out worlds. Without the restrictions of gravity, their brains have grown to monstrous sizes. The Asteromorphs eventually evolved into god-like creatures with even more massive brains. After a victorious war against the Gravital machine empire, they became the undisputed dominant race in their home galaxy, creating an intergalactic empire.
