Time travel is not forbidden by the laws of nature, but to build a time machine, we would need to understand more about those laws and how to subvert them than we do now. And every day, science does learn more. In this film Horizon meets the scientists working on the cutting edge of discovery - men and women who may discover how to build wormholes, manipulate entangled photons or build fully functioning time crystals. In short, these scientists may enable an engineer of the future to do what we have so far been only able to imagine - to build a machine that allows us travel back and forward in time at the touch of a button. It could be you! Science fiction?

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!

Over 100 years ago, Albert Einstein grappled with the implications of his revolutionary special theory of relativity and came to a startling conclusion: mass and energy are one, related by the formula E = mc2. In "Einstein's Big Idea," NOVA dramatizes the remarkable story behind this equation. E = mc2 was just one of several extraordinary breakthroughs that Einstein made in 1905, including the completion of his special theory of relativity, his identification of proof that atoms exist, and his explanation of the nature of light, which would win him the Nobel Prize in Physics. Among Einstein's ideas, E = mc2 is by far the most famous. Yet how many people know what it really means? In a thought-provoking and engrossing docudrama, NOVA illuminates this deceptively simple formula by unraveling the story of how it came to be.

Extra dimensions of space — the idea that we are immersed in hyperspace — may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einstein’s subsequent work envisioned more dimensions still — but ultimately hit a dead end. Modern research has advanced the subject in ways he couldn’t have imagined. John Hockenberry joins Brian Greene, Lawrence Krauss, and other leading thinkers on a visual tour through wondrous spatial realms that may lie beyond the ones we experience.

The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object.
