Starburst is a science fiction novel by American writer Frederik Pohl, published in 1982.
It is an expansion of his 1972 novella The Gold at the Starbow's End.
Starbust is a novel in which an astronaut crew goes from being doomed to becoming superpowered.
[1] Dave Langford reviewed Starburst for White Dwarf #54, and stated that "OK at novelette length but Pohl just hinted at the details of their offstage apotheosis: but the more you hear about it the less likely it sounds, and the book becomes a prolonged anticlimax.
A smooth read, yes, but the original story is diluted to insipidity.
