We float along the river of time. But does that river have a source? Where did time come from? Some believe time and space are one thing, and the Big Bang started the cosmic clock. Others believe the universe existed for almost half a million "years" before light could move and time began. Still others say time is older than our universe. But what if time itself is an illusion? Incredible new experiments may hold the answer. One groundbreaking experiment gives us the power to punch holes in time…and another may create a machine that operates outside time’s boundaries!

In The Science of Interstellar, Kip Thorne, the physicist who assisted Nolan on the scientific aspects of Interstellar, shows us that the movie's jaw-dropping events and stunning, never-before-attempted visuals are grounded in real science. Thorne shares his experiences working as the science adviser on the film and then moves on to the science itself. In chapters on wormholes, black holes, interstellar travel, and much more, Thorne's scientific insights-many of them triggered during the actual scripting and shooting of Interstellar-describe the physical laws that govern our universe and the truly astounding phenomena that those laws make possible.

Foo Fighters commemorate their 20th anniversary by documenting the eight-city recording odyssey that produced their latest, and eighth, studio album. Foo Fighters founder Dave Grohl directs the series, which taps into the musical heritage and cultural fabric of eight cities: Chicago, Austin, Nashville, Los Angeles, Seattle, New Orleans, Washington D.C. and New York. The band based themselves at a legendary recording studio integral to the unique history and character of each location. One song was recorded in each city, and every track features local legends. Even the lyrics were developed in an experimental, unprecedented way: Grohl held off on writing them until the last day of each session, letting himself be inspired by the experiences, interviews and personalities that became part of the process. Foo Fighters Sonic Highways is, in Grohl’s words, “a love letter to the history of American music.” Each episode delves into the identity of each city -- showing how each region shaped these musicians in their formative years and, in turn, how they impacted the cultural fabric of their hometowns. Every artist who appears in the show, regardless of genre or locale, started as an average kid with universal dreams of making music and making it big. Grohl made his feature film directorial debut in 2013 with the universally acclaimed Grammy-winning Sound City, a celebration of the human element in the creation and recording of music. Foo Fighters have won 11 Grammy Awards, including four for Best Rock Album, more than any other band. Premiering on the eve of Foo Fighters’ 20th anniversary, Foo Fighters Sonic Highways aims to “give back” to the next generation of young musicians. As guitarist and singer Buddy Guy, an interviewee from the Chicago blues scene, explains, “Everything comes from what’s come before.”
In the first episode, Dave Grohl and friends discuss the rise of the famous Chicago music scene from the roots blues of Muddy Waters and Buddy Guy to the Rock and roll of Cheap Trick.

'The Coldest War': With the polar ice caps shrinking due to global warming, new trade routes are being exposed, along with billions of dollars' worth of natural-resource reserves. The five nations bordering the Arctic are readying themselves to fight for it. The problem is that there's one non-NATO country that already considers itself rightful owner of the region: Russia. With Vladimir Putin's recent military annexation of Crimea, there's a definite possibility its aggressions will boil over, returning the international community to precarious Cold War footing. We will head north to witness NATO forces participating in the largest polar military exercise in history. 'Heroin Warfare': Since the U.S. occupation of Afghanistan, heroin production in the region has skyrocketed, making the country the number-one producer by a large margin. Though Iran, Afghanistan's neighbor, is an ultraconservative country, Afghan heroin flowing across the border has actually caused Iran to have the worst heroin use problem in the world. Suroosh Alvi gets a rare look inside Iran to meet the suffering heroin addicts, and see how the country is coping with the illegal drug trade.
