What Is the Biggest Thing in the Universe?

This documentary sets out to answer a deceptively simple question: what is the largest structure in the entire universe? It journeys up the cosmic ladder from planets and stars to galaxies, clusters and the vast filaments of the cosmic web. Along the way it explains how astronomers measure such staggering scales and why the answers stretch the imagination. Clear, visual and full of wonder, it is a satisfying tour of the biggest things science has ever found. Free to watch in HD on Dr Documentary.
