Can science understand everything? NASA scientists attempt to answer the question

‘Please define everything…’

This short documentary is built around a single question posed in 2005-6 to scientists working at the NASA Space Sciences Laboratory at the University of California, Berkeley: ‘Do you think science can understand everything?’ Most of them pause or take a deep breath before venturing out on such thin ice. From seeking clarity on the meaning of the question, to weighing careful, nuanced answers, to relative certainty one way or the other, their perspectives provide a fascinating window on to the varying motivations and world views of scientists working at the frontiers of human knowledge.
