Zach charts a journey to determine whether time travel is possible. He meets a man who claims to have traveled back in time due to a secret government program and a group of people living in Liverpool known as “time slippers.” Zach then makes an visit to the CERN headquarters in Geneva, where he attempts to understand the origins of the universe and the dimension of time. Equipped with this new knowledge, Zach tests his own perception of time with an elaborate skydiving experiment to see if he can slow down time itself.

Light always travels at a speed of 299,792,458 meters per second. But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible! In this second installment of a three-part series on space-time, CERN scientists Andrew Pontzen and Tom Whyntie use a space-time diagram to analyze the sometimes confounding motion of light.
This is an astonishing tale of perseverance and ingenuity that reveals how scientists have battled against the odds for almost a century to detect and decode the neutrino, the smallest and strangest particle of matter in the universe. Inside the world-renowned physics laboratory Fermilab, a team of scientists are constructing an audacious experiment to hunt for a mysterious new 'ghost' neutrino. If they find it, this could transform our understanding of the nature and fabric of our universe. The problem is, these tiny particles are almost impossible to detect. Elsewhere, physicists conduct experiments in some of the most extreme environments on the planet: from deep mine shafts in South Dakota to vast ice fields at the South Pole. In these unlikely places supersized neutrino detectors hope to unlock the universe's deepest secrets. Could neutrinos overturn the most precise theory of particle physics that humans have ever written down? Could they even be a link to a hidden realm of new particles that permeate the cosmos - so called dark matter? Scientists at Fermilab are edging towards the truth.

A unique and captivating documentary on the story of humanity's quest to measure time. Who invented time, who invented the clock? Why 1 hour, why 60 minutes, why 60 seconds? Since prehistoric times, man has sought to measure time, to organize social and religious life, to plan food supply... Today we can surf the Internet, geolocate, pay by credit card ... All our daily lives depend on time and the synchronization of clocks. The history of the invention of time and of the ways and instruments to measure it is a long story... Controlling Time, one of Humanity's biggest obsessions. First, man began to calculate the observable phenomena of time using incredible astronomical measuring instruments. Calendars were born. Then, he sought to quantify ever more precise durations, with ever more sophisticated machines, in order to establish a social, conventional time, the same for all. Today, this time, inscribed on our smartphones, is established by atomic clocks which have become the keystone of our digital world. Not without enormous industrial and economic challenges at stake. Through what major technological breakthroughs have we succeeded in controlling time, to the point of being able to make its ultra-precise factory the foundation of our interconnected society? From France to Greece, through Italy, England, and Switzerland, a group of experts —astrophysicists, engineers and historians — follows in the footsteps of genius inventors who forged our perception of time and our relationship to the world. For better and for worse. This film delves into the invention of time & ways to measure it. Don't waste time and be sure to make time to watch this fascinating film!
