that's how i learned it (equally stressed syllables) from my history of science professor, who (sadistically) assigned gravity's rainbow for the meticulously researched, and fanciful, historical digressions strewn throughout the book. glad to know he wasn't wrong about the pronunciation.

that was my intro to pynchon, being thrown head-first into the deep end. i did actually read the book, but it was... challenging. i appreciate the experience in hindsight, but rued every minute of it at the time.
