Everything and Nothing: Part 1, "Everything"
This documentary, the first of a pair, follows physicist Jim Al-Khalili as he asks a childlike question with a vast answer: why does it get dark at night? The inquiry opens onto the size and boundaries of the known universe and our understanding of space. The film turns everyday wonder into a serious scientific journey. It is a rewarding watch for anyone interested in physics, astronomy, and the true scale of the cosmos. Free to watch in HD on Dr Documentary.
