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!
We are all at the mercy of the Sun. Its glowing disc sustains nearly all life on Earth. But the Sun also holds a dark secret: someday, our aging, expanding star will bathe the Earth in a fiery holocaust. Everything we know will turn to hot, bubbling, plasma.
It's called the speed limit of the universe. Einstein blew all of our minds when he worked out the Theory of Relativity, and showed that space and time were malleable substances. He also theorized that we as humans can never travel faster than the speed of light, which leaves the stars and other galaxies almost impossibly out of our reach. But the dreams of Star Wars and Star Trek are not dead. In fact, there could be ways to travel faster than the speed of light - and some of them are already being tested in labs around the world.
Quantum theory, the best explanation of how atoms and anything smaller behave, is so weird even scientists who have mastered it find it baffling. But bit by bit scientists are finding maybe it's not so weird as comparable behavior is discovered in our every day world. It's just that no one noticed before.
Our minds store our entire lives, our memories and our deepest desires. Tell no one, and our thoughts remain our own. But our brains are biological computers. Computer hackers can tamper with our email. Could brain hackers someday be able to rewrite our thoughts?
Our universe seems real. But what if it’s a videogame? Scientists in a variety of fields are taking seriously the possibility that we live in a virtual reality. Maybe the Big Bang was just the moment someone flipped the switch and turned on our universe. Maybe what looks random has already been programmed to happen. If some advanced civilization did design and program our universe, would we ever know? Scientists are looking for glitches in the laws of the universe that may uncover its hidden code.
Death is life's greatest certainty. But that may be about to change. Scientists have discovered an immortal animal that may hold the secret of endless regeneration. They're on the brink of editing our DNA so that we can cure death like a disease. Or is dying necessary for the survival of our species?

You may think you know who wrote the Declaration of Independence and what it says -- but do you really? Political theorist Danielle Allen looks at the document's origin and originators to give us a picture of the men and the moment in time that shaped the United States of today.
It's perfectly human to grapple with questions, like 'Where do we come from?' and 'How do I live a life of meaning?' These existential questions are central to the five major world religions -- and that's not all that connects these faiths. John Bellaimey explains the intertwined histories and cultures of Hinduism, Judaism, Buddhism, Christianity and Islam.

He Named Me Malala is an intimate portrait of Nobel Peace Prize Laureate Malala Yousafzai, who was targeted by the Taliban and severely wounded by a gunshot when returning home on her school bus in Pakistan’s Swat Valley. The then 15-year-old (she turns 18 this July) was singled out, along with her father, for advocating for girls’ education, and the attack on her sparked an outcry from supporters around the world. She miraculously survived and is now a leading campaigner for girls’ education globally as co-founder of the Malala Fund. Acclaimed documentary filmmaker Davis Guggenheim (An Inconvenient Truth, Waiting for Superman) shows us how Malala, her father Zia and her family are committed to fighting for education for all girls worldwide. The film gives us an inside glimpse into this extraordinary young girl’s life – from her close relationship with her father who inspired her love for education, to her impassioned speeches at the UN, to her everyday life with her parents and brothers. - “One child, one teacher, one book and one pen can change the world." – Malala
