Omega Minor is a 2004 novel by the Belgian writer Paul Verhaeghen.

The narrative follows a number of European research students and their theories about the Omega density parameter and the nature of dark matter, as well as ponders on the violence of World War II.

[1] Matt Thorne reviewed the book for The Independent: "Among authors of big novels that address science, technology and psychology, Verhaeghen is closer to William T Vollmann, Don DeLillo and the underrated British author James Flint than Thomas Pynchon or David Foster Wallace.

He has almost no interest in popular culture and his conspiracy theories tend to focus on historical injustice rather than sinister cabals.

Thorne continued: "Omega Minor is undoubtedly a curate's egg, but few recent novels rival its richness.
