Beyond the Big Bang

   2007    Science
The universe began with a massive expansion, billions and billions of years ago, and it continues to expand with every passing second. The idea that the universe, and man's very existence, began with a "Big Bang" is no longer a topic of debate among most scientists--it is essentially taken as fact.

When Did Time Begin

   2014    Science
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!

Parallel Universes

   2008    Science
Some of the world's leading physicists believe they have found startling new evidence showing the existence of universes other than our own. One possibility is that the universe is so vast that an exact replica of our solar system, our planet and ourselves exists many times over. These Doppelganger Universes exist within our own Universe; in what scientist now call "The Multiverse." If proof is found it will change our lives, our minds, our planet, our science and our universe.

Still a Revolutionary: Albert Einstein

   2020    History
Albert Einstein, the most famous scientist of all time, was a world-renowned celebrity, greeted like a rock star when he appeared in public. An anti-war firebrand, Einstein also spoke out on issues ranging from women's rights and racism to immigration and nuclear arms control. But today, his image has been neutered into that of a charmingly absent-minded genius. He was, in fact, a powerful force for social change and a model for political activism.
Using a wealth of rarely-seen archival footage, correspondence, and new and illuminating interviews, filmmaker Julia Newman makes the case that Albert Einstein's example of social and political activism is as important today as are his brilliant, groundbreaking theories.

What are We Really Made of

   2011    Science
What is the universe made of? If you answered stars, planets, gas and dust, you'd be dead wrong. Thirty years ago, scientists first realized that some unknown dark substance was affecting the way galaxies moved. Today, they think there must be five times our understanding of the universe and the nature of reality itself has drastically changed over the last 100 years - and it's on the verge of another seismic shift. In a 17-mile-long tunnel buried 570 feet beneath the Franco-Swiss border, the world's largest and most powerful atom smasher, the Large Hadron Collider, is powering up. Its goal is nothing less than recreating the first instants of creation, when the universe was unimaginably hot and long-extinct forms of matter sizzled and cooled into stars, planets, and ultimately, us. These incredibly small and exotic particles hold the keys to the greatest mysteries of the universe. What we find could validate our long-held theories about how the world works and what we are made of -- or, all of our notions about the essence of what is real will fall apart.
