The Odds of Discovering Life and Romance

PBS Member Stations rely on viewers like you. To support your local station, go to: http://to.pbs.org/DonateOKAY ↓ More info and sources below ↓ A cosmic love story, starring a guy named Carl Sagan Click here to SUBSCRIBE, it's FREE! -- http://bit.ly/iotbs_sub Love is a complicated combination of brain chemicals and behavior that scientists are only just beginning to figure out. And it's remarkable that in every society that we have looked at on Earth, romantic love exists. So if love is so universal, and there are 7 billion other people out there looking for it, why can it seem like it's so hard to find? In this episode, we'll look at what we can learn about the search for love from the search for extraterrestrial life. We'll start with Enrico Fermi's paradox of why we haven't been contacted by any extraterrestrials yet, and then at Frank Drake's equation to estimate the number of civilizations that might exist in our galaxy (updated with current numbers). Finally, we'll meet a young lady named Ann and see if we can calculate how many special someones there might be out there for her. It's a cosmic love story!

When Will We Stop Consuming Oil?

Rising CO2 levels and the changing climate that results from burning fossil fuels mean that we should probably stop using oil sooner rather than later, though Let's take a look at history and see how we've used different fuels, so that we might figure out when and how to make oil a thing of the past LEARN MORE: Special thanks to Sheril Kirshenbaum and the Webber Energy Group at the University of Texas at Austin for their help with this series. http://www.webberenergygroup.com/ Check out their awesome online course "Energy 101" to learn about energy and energy policy from A to Z! http://www.energy101.com/ And to find out what people think about energy, check out the UT Energy Poll: http://www.utenergypoll.com/ Have an idea for an episode or an amazing science question you want answered?
