  1. 01Horizon S2016E04Oceans of the Solar SystemS2016E04 · 9.0The oceans define the earth. They are crucial to life and we used to think that they were unique to our blue planet. But we were wrong.It has recently been discovered that there are oceans all over our solarsystem and they are very similar to our own. And now scientists are going on an epic journey in search of new life in places that never seemed possible. Nasa is even planning to dive to the depths of a strange, distant ocean in a remarkable submarine.Horizon discovers that the hunt for oceans in space is marking the dawn of a new era in the search for alien life.
  2. 02How to Build a Time MachineS2018E03 · 7.5Time 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? Watch this space.
