¿¡Y tú que (s)abes!? was released in the year 2004。¿¡Y tú que (s)abes!? is also called as What the #$*! Do We (K)now!?, Ti sto... biip... xeroume?, Sacred Science, Quem Somos Nós?, ¿Y tú qué sabes?, What the Bleep Do We Know!?。

"WHAT THE #$*! DO WE KNOW?!" is a radical departure from convention. It demands a freedom of view and greatness of thought so far unknown, indeed, not even dreamed of since Copernicus. It's a documentary. It's a story. It's mind-blowing special effects. This film plunges you into a world where quantum uncertainty is demonstrated - where neurological processes, and perceptual shifts are engaged and lived by its protagonist - where everything is alive, and reality is changed by every thought.

¿¡Y tú que (s)abes!? actors and actresses include Armin Shimerman, Elaine Hendrix, John Ross Bowie, Marlee Matlin, Robert Blanche, Tin Tran。
