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.

What Are We Really Made of?

#2 - What Are We Really Made of?

Season 1 - Episode 7

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.

Does Time Really Exist?

#4 - Does Time Really Exist?

Season 2 - Episode 3

It is a question that has vexed philosophers and scientists for centuries; 'What is Time?' Exactly how is our past, present, and future connected by that arrow of cause and effect that we call Time? Is time simply another dimension, just like the dimensions of space we know? Can you run time backwards just as easily as it runs forward, just as left-to-right can swap for right-to-left? If other universes exist, then what is time like in them: could their Time be different from ours? And we'll probe the biggest question about time: Is our future determined? Do we exercise free will? Or, is time merely a dream?

Is Gravity an Illusion?

#6 - Is Gravity an Illusion?

Season 5 - Episode 7

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 There an Edge to the Universe?

#13 - Is There an Edge to the Universe?

Season 2 - Episode 2

It is commonly theorized that the universe began with the Big Bang 13.7 billion years ago. But since we can only see as far as light has traveled in that time, we can't actually make out the edge of the universe. Could it be that the universe is infinite? Is there any way to find out what the shape of the universe really is? Can we find the edge, discover what might lie beyond it, and perhaps even discover a universe next to ours?

Is There a Shadow Universe?

#14 - Is There a Shadow Universe?

Season 5 - Episode 9

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?

Beyond the Darkness

#15 - Beyond the Darkness

Season 1 - Episode 8

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.

Can We Travel Faster Than Light?

#20 - Can We Travel Faster Than Light?

Season 2 - Episode 7

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.

How Does the Universe Work?

#21 - How Does the Universe Work?

Season 2 - Episode 6

Since the ancient Greeks first speculated that everything they observed in reality was the result of the interaction of tiny particles they called atoms, great thinkers have tried to find a single mathematical formula that governs and explains the workings of the entire universe. So far, though, even minds as brilliant as physicists Albert Einstein and Stephen Hawking have been unable to come up with that single grand equation of everything, also known as the theory of everything, or the final theory. Nevertheless, they continue to try, because without that final piece of the puzzle that is reality, the sum total of what we know falls a bit short of making sense.

Did We Invent God?

#22 - Did We Invent God?

Season 3 - Episode 10

Our belief in a God above explains all we can't understand. Where do religious beliefs come from? Some experts believe God may exist only in our brain, that we are wired to worship the supernatural and that faith in a higher power gives us an evolutionary advantage. Is it possible that God is really just a neurological accident? And does that make Him any less real? Did God invent humanity, or did humanity invent God?

The Riddle of Black Holes

#23 - The Riddle of Black Holes

Season 1 - Episode 2

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.

Is God an Alien Concept?

#24 - Is God an Alien Concept?

Season 5 - Episode 1

Is God worshipped in other worlds, across the cosmos? How might alien deities differ from our own? The answer may lie buried on Earth. Animal behaviorists are testing elephants and finding them capable of having spiritual thoughts. Artificial intelligence researchers are building enlightened robots that contemplate the divine. Meanwhile, cosmologists are looking for universal equations that could replace God. Have advanced aliens discovered everything there is to know about the universe? Or are they looking to a higher power for answers?

Is There a Sixth Sense?

#25 - Is There a Sixth Sense?

Season 2 - Episode 5

Can we perceive objects and events beyond the world detected by our five senses? The true limits of our human brain remain a scientific mystery. New studies in neuroscience are showing that our minds can really detect events and objects that our conscious selves know nothing about. Can we predict events in the future? Is there such a thing as a global consciousness? Could physical laws on the cusp of being discovered be at the root of all this?
