Network: Science Channel

Hosted by Morgan Freeman, Through the Wormhole explores the deepest mysteries of existence - the questions that have puzzled mankind for eternity. What are we made of? What was there before the beginning? Are we really alone? Is there a creator? These questions have been pondered by the most exquisite minds of the human race. Now, science has evolved to the point where hard facts and evidence may be able to provide us with answers instead of philosophical theories. Through the Wormhole brings together the brightest minds and best ideas from the very edges of science - Astrophysics, Astrobiology, Quantum Mechanics, String Theory, and more - to reveal the extraordinary truth of our Universe.

Is There a Shadow Universe?

#1 - Is There a Shadow Universe?

Season 5 - Episode 9 - Aired Jul 23, 2014

When we look up into the sky it appears we live in a universe that is filled with light. But scientists are now certain there is far more matter in the dark portions of our universe that we can’t see or touch. There’s something hiding in the shadows. Cosmologists agree that "dark matter" has helped shape our Universe, but now they need to figure out what dark matter is. What’s going on in this hidden world? Could it have formed its own dark stars, planets, and even life forms? Could this Shadow Universe threaten our world of light?

Is Gravity an Illusion?

#3 - Is Gravity an Illusion?

Season 5 - Episode 7 - Aired Jul 9, 2014

We feel it every moment of our lives but for physicists, gravity is the longest running unsolved mystery of the universe. Why do all objects that have mass pull on one another? Cutting-edge theories are proposing unexpected answers: Gravity could be another force in disguise, a thermodynamic mirage, or even, a shadow of a hidden holographic universe. If so, the force that holds us to the surface of the earth, and holds the earth in orbit around the sun, may be a trick of the mind. We feel it, but it may not be real. Is Gravity an Illusion?

Is Poverty Genetic?

#5 - Is Poverty Genetic?

Season 5 - Episode 3 - Aired Jun 11, 2014

Are the wealthy just born in the right place at the right time? Are the poor victims of a system designed to keep them down? Or do physics and biology determine who is rich and who is poor? Throughout history, distribution of wealth is governed by hidden forces: DNA, environmental stress, patterns of human migration and even the laws of thermodynamics! Nature seems to demand winners and losers in life. But does this mean greed is king, and the rich can take what they want? Or is cooperation – between microorganisms, monkeys, and humans – more essential to survival of a species?

The Riddle of Black Holes

#12 - The Riddle of Black Holes

Season 1 - Episode 2 - Aired Jun 16, 2010

They are the most powerful objects in the universe. Nothing, not even light, can escape the gravitational pull of a black hole. Astronomers now believe there are billions of them out in the cosmos, swallowing up planets, even entire stars in violent feeding frenzies. New theoretical research into the twisted reality of black holes suggests that three-dimensional space could be an illusion. That reality actually takes place on a two-dimensional hologram at the edge of the universe.

What Are We Really Made of?

#14 - What Are We Really Made of?

Season 1 - Episode 7 - Aired Jul 21, 2010

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.

Are you sure? The outcome – whatever your race – will surprise you. Brain imaging studies are showing that negative cultural stereotypes hijack everyone’s subconscious decision-making. But some science says we can overcome bigotry through exposure, self-awareness and flexible social networks… and, most controversially of all, ultra-violent video games!

Beyond the Darkness

#20 - Beyond the Darkness

Season 1 - Episode 8 - Aired Jul 28, 2010

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 as much dark matter as regular matter out there. But they have no idea what it is — only that it's not made of atoms, or any other matter we are familiar with. And Dark Matter is not the only strange substance in the Universe — a newly discovered force, called Dark Energy, seems to be pushing the very fabric of the cosmos apart.
