"Steven Spielberg is set to defy gravity in a new film he will direct for Paramount Pictures.

The Oscar-winning filmmaker's latest venture is an untitled sci-fi film that delves into Caltech physicist Kip Thorne's theories of gravity fields.

Although the project is considered embryonic -- it has no screenplay and would likely take at least three years to make -- Thorne wrote a treatment with the help of producer and science enthusiast Lynda Obst, prompting Spielberg's involvement.

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

Based on real science, the film would 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.

It is unclear how Thorne's scientific theories will evolve into a film-ready narrative, but the concept has been described as in the vein of ""2001: A Space Odyssey.""

Spielberg, who directed last year's summer tentpole ""War of the Worlds"" for Paramount, is developing and producing another sci-fi thriller, ""When Worlds Collide,"" for the studio.

Although he has not picked the project he will direct next, there are at least two leading candidates: ""Indiana Jones 4"" for Paramount and an untitled Abraham Lincoln biopic for DreamWorks.
