What If is a Webby Award-winning science documentary web series that takes you on an epic journey through hypothetical worlds and possibilities, some in distant corners of the universe, others right here on Earth. Each scenario examines a scientific theory, research or fact through hypothetical questions that fascinate and engage. By combining human perspectives with an almost inexhaustible pool of science-based imaginations we get a glimpse into humankind's delicate existence in an otherwise hostile universe.
