Steven Spielberg is attached to direct an untitled sci-fi film for Paramount Pictures that delves into Caltech physicist Kip Thorne's theories of gravity fields, says The Hollywood Reporter.

Although the project is considered embryonic -- there is no screenplay yet and would likely be three to four years away from fruition -- Thorne wrote a treatment with the help of producer and science nut Lynda Obst, prompting Spielberg's involvement.

Obst ("How to Lose a Guy in 10 Days") will produce the film through her Paramount-based shingle.

Based on real science, the film will explore the mind-bending territory of black holes and gravity waves and touch on some of the hypotheses that Albert Einstein chased but never could prove. Thorne, a longtime friend of Obst's, is one of the world's leading experts on relativity.
