PBS Space Time Season 2017 Episode 10 Time Crystals!

PBS Space Time is a popular science-based show that explores the mysteries of the universe and provides its viewers with cutting-edge science and technology information. In season 2017, the show aired its 10th episode titled "Time Crystals!" that delves into the latest groundbreaking discovery in the field of physics.

In this episode, the show's host, Matt O'Dowd, takes the viewers on a fascinating journey of exploration into the weird and wonderful world of time crystals. According to Matt, time crystals are a new state of matter that scientists have recently discovered, and they could have far-reaching implications for our understanding of the universe.

The episode begins by explaining what time crystals are and how they were first discovered. As Matt explains, time crystals are extraordinary materials that spontaneously move in a repeating pattern, even when they are at a state of rest. Put simply, time crystals are materials that oscillate not only in space, as crystals do, but also in time.

Matt goes on to explain the incredible properties of time crystals, including the fact that they have a certain type of symmetry that has never before been observed in nature. This symmetry is called "time-translation symmetry breaking," and it tells us that time crystals behave differently depending on the time axis in which they are observed.

The host then delves deeper into the physics behind time crystals, particularly the phenomenon of coherence, which is the ability of a system to remain in a well-defined quantum state over time. Coherence is crucial to understanding the behavior of time crystals, as it allows these crystals to maintain their repeating patterns over time.

Matt also explains the cutting-edge experiments that are being conducted to explore time crystals, including the use of lasers and magnetic fields to create and study these unique materials. He also describes the various challenges that scientists face in understanding and manipulating these materials, including the need to develop better tools for measuring them.

Towards the end of the episode, Matt discusses the potential applications of time crystals in technology, including the creation of new types of computer memory and other advanced devices. He also emphasizes the philosophical implications of time crystals, particularly the way in which they challenge our notions of time and space.

Overall, "Time Crystals!" is a fascinating and thought-provoking episode that offers a glimpse into the cutting-edge of physics research. It provides audiences with an accessible and engaging overview of this new and exciting area of science, exploring not only the science but also the potential implications for our understanding of the universe and for technological advancements in the future.
