UNSEEN UNIVERSE VERSION (SUBTITLES) REVISED: SEP 11, 2019 SCENE TIME SCRIPT TITLES OPENING TITLES 01:00 UNSEEN UNIVERSE INTRO INTRODUCTION 00:40 We are creatures of sight, always trying to see farther and in greater detail, exploring the distant universe far beyond our other senses. 01:15 A fleet of huge instruments are our new eyes on the cosmos, tuned to all the colors of light. Airborne telescopes scan the heavens. Observatories on high mountain peaks stare through Earth's clear skies, and spread across vast dry deserts, huge telescopes watch the sky. Radio ears as big as a football stadium capture the lowest frequencies of light. 01:53 Another radio device the size of a kitchen table discovered that the stars first began to shine nearly 13 billion years ago, just after the universe began. To capture some of the most elusive particles buried detectors are deep underground, even under the ice, at the south pole, at the Ice Cube Observatory. 02:35 Why so many instruments in so many different places? Because so much is happening that we cannot see we need devices to reveal what our eyes cannot. These instruments show us a universe that is real but not visible to our eyes. We see the result of powerful forces - nuclear, gravitational and magnetic, driving change in the universe. 03:09 There is a cosmic drama in the heavens above, with scenes and characters we've never seen before. It's magnificent, it's beautiful, it's fascinating, it's startling, surprising, enigmatic, and forever puzzling.
