#1 - The Riddle of Black Holes
S1:E26/16/2010
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.

#2 - What Happened Before the Beginning?
S1:E46/30/2010
Every cosmologist and astronomer agrees: our Universe is 13.7 billion years old. Using cutting-edge technology, scientists are now able to take a snapshot of the Universe a mere heartbeat after its birth. Armed with hypersensitive satellites, astronomers look back in time to the very moment of creation, when all the matter in the Universe exploded into existence. It is here that we uncover an unsolved mystery as old as time itself — if the Universe was born, where did it come from? Meet the leading scientists who have now discovered what they believe to be the origin of our Universe, and a window into the time before time.

#3 - Beyond the Darkness
S1:E87/28/2010
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.

#4 - Is Time Travel Possible?
S1:E36/23/2010
Einstein's Theory of Relativity says that time travel is perfectly possible — if you're going forward. Finding a way to travel backwards requires breaking the speed of light, which so far seems impossible. But now, strange-but-true phenomena such as quantum nonlocality, where particles instantly teleport across vast distances, may give us a way to make the dream of traveling back and forth through time a reality. Step into a time machine and rewrite history, bring loved ones back to life, control our destinies. But if we succeed, what are the consequences of such freedom? Will we get trapped in a plethora of paradoxes and multiple universes that will destroy the fabric of the universe?

#5 - Is There an Edge to the Universe?
S2:E26/15/2011
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?

#6 - What Are We Really Made Of?
S1:E77/21/2010
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.

#7 - Does Time Really Exist?
S2:E36/22/2011
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?

#8 - Are Robots the Future of Human Evolution?
S4:E77/10/2013
We are in the midst of a revolution so insidious we can't even see it. From our telephones to our vacuum cleaners to our cars, we have robots that live and work beside us. And now we're designing them to think for themselves, giving them the power to learn to move on their own.

#9 - Is There a Creator?
S1:E16/9/2010
It's perhaps the biggest, most controversial mystery in the cosmos. Did our Universe just come into being by random chance, or was it created by a God who nurtures and sustains all life? The latest science is showing that the four forces governing our universe are phenomenally finely tuned. So finely that it had led many to the conclusion that someone, or something, must have calibrated them; a belief further backed up by evidence that everything in our universe may emanate from one extraordinarily elegant and beautiful design known as the E8 Lie Group. While skeptics hold that these findings are neither conclusive nor evidence of a divine creator, some cutting edge physicists are already positing who this God is: an alien gamester who's created our world as the ultimate SIM game for his own amusement. It's an answer as compelling as it is disconcerting.

#10 - How Did We Get Here?
S1:E57/5/2010
Everywhere we look, life exists in both the most hospitable of environments and in the most extreme. Yet we have only ever found life on our planet. How did the stuff of stars come together to create life as we know it? What do we really mean by 'life'? And will unlocking this mystery help us find life elsewhere?

S2:E87/27/2011
Medical advances have doubled human life expectancy in past centuries. But can humans ever beat death altogether? Can we control and fix the errors that build up in our DNA over the years? Can we find a way to replace the chemistry of life with something more durable? This episode wonders into the mystifying definition of 'eternity' as it relates to human lifespan.

#12 - Are We Alone?
S1:E67/14/2010
Aliens almost certainly do exist. So why haven't we yet met E.T.? It turns out we're only just developing instruments powerful enough to scan for them, and science sophisticated enough to know where to look. As a result, race is on to find the first intelligent aliens. But what would they look like, and how would they interact with us if we met? The answers may come to us sooner than we imagine, for one leading astronomer believes she may already have heard a hint of their first efforts to communicate.

#13 - How Does the Universe Work?
S2:E67/13/2011
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.

#14 - Are There More Than 3 Dimensions?
S2:E46/29/2011
We move and live in three dimensions: length, width, and height. However, Einstein revealed what was once unimaginable: time is actually a dimension and linked with space itself. To reconcile the massive cosmic and miniscule quantum worlds, physicists are realizing four dimensions may not be enough. They're unraveling up to eleven dimensions. How could this be true? Where could these dimensions be?

#15 - Can We Travel Faster than Light?
S2:E77/20/2011
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.

#19 - Is There Life After Death?
S2:E16/8/2011
In the premiere episode of the second season, Morgan Freeman dives deep into this provocative question that has mystified humans since the beginning of time. Modern physics and neuroscience are venturing into this once hallowed ground, and radically changing our ideas of life after death. Freeman serves as host to this polarized debate, where scientists and spiritualist attempt to define 'what is consciousness,' while cutting edge quantum mechanics could provide the answer to what happens when we die.

#20 - Is There a Sixth Sense?
S2:E57/6/2011
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?

#21 - What Do Aliens Look Like?
S2:E98/3/2011
Science fiction writers have always had their little green men. But these humanoid aliens were based soundly on Earth-based life, not any extra terrestrial evidence. Today, we've discovered hundreds of planets around other stars. As we learn what some of these alternative Earths might look like, science and imagination have allowed us to use real science to imagine the biology of their inhabitants. Will they have two eyes? Two legs? What color will their skin be? Which species on Earth can give us clues about likely biology of aliens? And what can we learn from how life on Earth developed to help us understand what ET really looks like?

#22 - When Did Time Begin?
S5:E107/23/2014
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!

#24 - Are There Parallel Universes?
S2:E109/4/2011
Most scientists believe that you are not really you, but rather, you all. On the edge of space, buried in a black hole, or right on top of you, there could be an exact copy of yourself living a parallel reality. In those parallel worlds, you may be living your wildest dreams, or your worst nightmares. Finding them is no longer restricted to the realm of science fiction. Recent game-changing theories now suggest that if these worlds exist, intelligent life in these alternative worlds could be trying to send us messages. As scientists further unravel this astounding possibility, a new possibility emerges: the fate of our entire universe may depend on these hidden cosmic twins.

#25 - Did We Invent God?
S3:E108/8/2012
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?
