Plot Synopsis

INVISIBLE WORLDS uses state-of-the-art cameras to document what happens beyond the limits of human vision. This three-episode series highlights things that are too small to see ("Off the Scale"), too fast to observe ("Speed Limits") or outside the visible spectrum ("Out of Sight"), answering questions like which organism can accelerate the fastest? (Answer: A spore can go from 0-20mph in two millionths of a second.) In the UK, this series was part of WORLD OF WONDER, a year of science programming on BBC in 2010.
