How can structures, which take up defined, rigid portions of space, make us feel transcendence? How can chapels turn into places of introspection? How can walls grant boundless freedom? Driven by intense childhood impressions, director Christoph Schaub visits extraordinary churches, both ancient and futuristic, and discovers works of art that take him up to the skies and all the way down to the bottom of the ocean. With the help of architects Peter Zumthor, Peter Märkli, and Álvaro Siza Vieira, artists James Turrell and Cristina Iglesias, and drummer Sergé “Jojo” Mayer, he tries to make sense of the world and decipher our spiritual experiences using the seemingly abstract concepts of light, time, rhythm, sound, and shape. The superb cinematography turns this contemplative search into a multi-sensory experience.

The use of embryonic stem cells has ignited fierce debate across the spiritual and political spectrum. But what if we could create manmade stem cells - or find super cells in adults that could forever replace embryonic cells and remove the controversy? Today, we are on the brink of a new era - an age where we may be able to cure our bodies of any illness. Stephen HAWKING has spent his life exploring the mysteries of the cosmos, now there is another universe that fascinates him - the one hidden inside our bodies - our own personal galaxies of cells.

Armenian radio-engineer Arevik Sargsyan has struggled throughout her life to preserve ROT54, a giant telescope built by her uncle in the 1980s.
