At the South Pole, the question “what time do we meet?” it is difficult to answer. Since it is the space in which the time zones are until they disappear and the reference of day and night does not work. The inhabitants decide the time zone they want to live their routine.

For example, scientific research bases from countries like the United States set time zones according to the home cities of the people who live there.

At the time of its launch, what do you know? It was a new kind of film: part documentary, part story, and part elaborate and inspiring visuals and animations. The protagonist, Amanda, played by Marlee Matlin, finds herself in a fantastic Alice in Wonderland-style experience when her boring and routine life literally begins to unravel and reveals the uncertain world of the quantum field that hides behind what we consider our normal waking reality.

As we watch Amanda struggle to understand the fundamental premises of her life, we see comments on her search for a multitude of scientists and mystics who serve as the Greek choir of modern times. His wisdom and ideas intertwine like a tapestry of truth, adding emphasis to the film’s underlying concept of the interconnectedness of all things.

Released in theaters for the first time in 2004, What do you know? It became one of the most successful documentaries of all time. Now distributed in more than 30 countries, it has wowed audiences around the world.
