How did starlin die?

Answer 1

Starlin died by being consumed by a black hole in the Delta Quadrant. While traveling throughout the different quadrants in our galaxy, Starlin came across a strange entity, that in fact was a black hole in disguise. Starlin, lacking any great mental capacity, fell for the black hole's trap and entered unknowingly. Hence, the great and late Starlin died via being consumed by a black hole in May 1951.
