PBS Space Time Season 2016 Episode 4 The Origin of Matter and Time
- January 27, 2016
PBS Space Time is a show produced by PBS Digital Studios that explores the mysteries of the universe, from the tiniest subatomic particles to the biggest questions about space and time. In season 2016 episode 4, titled The Origin of Matter and Time, the show delves into the origins of matter and time and their relationship to one another.
The episode opens with host Matt O'Dowd explaining that matter and time are intimately linked, as the particles that make up matter are constantly moving through time. He then introduces the concept of entropy, the tendency of matter to become more disordered over time, and how it is related to the arrow of time, or the direction in which time flows.
From there, O'Dowd delves into the history of the universe, starting with the Big Bang, and explains how scientists have been able to trace the evolution of matter from that initial explosion to the present day. Along the way, he explores concepts such as dark matter and dark energy, which make up the vast majority of the universe but remain shrouded in mystery.
As the episode progresses, O'Dowd also touches on the concept of symmetry, which plays a huge role in our understanding of the universe and its origins. He explains how the symmetry of fundamental particles such as quarks and leptons influences the properties of matter and contributes to the complexity of the universe we see around us.
Throughout the episode, O'Dowd uses numerous visual aids and analogies to help viewers grasp these complex concepts, such as a toy train set representing the different levels of symmetry in the universe. He also interviews several experts in the field, including physicist Sean Carroll and astronomer Neil deGrasse Tyson, to provide additional insight and perspectives on the topic at hand.
Ultimately, The Origin of Matter and Time is a fascinating look at some of the most fundamental questions about the universe and the forces that shape it. With its engaging and accessible approach to complex scientific concepts, it's sure to appeal to anyone with an interest in astronomy, physics, or the mysteries of the cosmos.
