What is the nature of the universe's greatest mystery, dark matter? Matter we are able to see with our eyes are only 5% of the universe. The rest is occupied by mysterious objects that exist but have no known form which we call "dark matter”. In this film, we deep dive into the history and the latest theoretical research of dark matter proposed by professor Lisa Randall and simulation images shared by professor Naoki Yoshida. We will also introduce observation facilities in Japan and around the world that are trying to capture dark matter itself.
