Episode Details

The astroquarks examine new observations of the rate of expansion of the universe and its consequences for Dark Energy, the mysterious force that is causing the expansion of the universe to accelerate. That, and what it would be like to live on Titan, a world where methane (natural gas) takes the place of water on the Earth: it rains methane into methane lakes, and it freezes out depending on the season. It's a veritable methanological cycle.
