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 sc…

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, sw…

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 imposs…

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 bi…

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 …

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 ventur…

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 t…

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? I…

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 mass…

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 …

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 mat…

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 tha…

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…

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 o…

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 parall…

Mankind longs for proof that we are not alone in the universe, but the moment of first contact will certainly mean the end of the world as we know it. Whether that is a bad thing for humanity or the s…

Does your subconscious know more than you ever will, and is your conscious mind holding you back? Do thoughts control actions, or vice versa? Research shows that opening the subconscious may make peo…

Many religious traditions have predicted that our world will come to an apocalyptic end. Scientists agree that Earth can't last forever, but disagree on whether the universe and time itself can ever d…

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 an…

Scientists explore the effects of the Higgs Boson discovery, which validates the Standard Model in particle physics and solidifies the understanding of subatomic particles; highlights include an in-de…

It is a debate that has raged for centuries’. Groundbreaking evidence reveals that inside all of us are traces of cells from our relatives, blurring the lines between one life and another. Technology …

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 holocau…

If the stuff of life is spread throughout the cosmos, then the universe could be teeming with aliens.

Every single person who has ever lived was created from the genes of one man and one woman. But human sexual reproduction, unchanged for millions of years, is about to undergo radical change.

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 emai…

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…

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…

What if everything that has or will happen in the universe has already been determined and we are unable to change our inevitable destinies? Until the discovery of quantum uncertainty, physicists were…

What or who created all of the billions of species that have lived on Earth? Is all life the product of evolution as Charles Darwin proposed or was it the guiding hand of a higher power?

Is God worshipped in other worlds across the cosmos? How might alien deities differ from our own? Have advanced aliens discovered everything there is to know about the universe, or are they too lookin…

Do you make your own luck or does luck make you? We find luck, good and bad, in casinos, basketball courts, genetics labs and the subatomic world. It’s a journey that will radically revise your unders…

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…

With a little imagination, could a few terrorists sabotage a mighty nation? Perhaps even tear down modern civilization? The stability of the US, Europe, China, or any global power depends on high-spee…

There could be an undiscovered species on Earth unlike anything we’ve ever known. Not in the ocean, but the ocean itself! Its body spans thousands of miles; its heart beats with a one-thousand-year pu…

It is a nightmare that has stalked us for centuries: hordes of human beings transformed into mindless, cannibalistic monsters. Could this civilization-ending nightmare become reality? Scientists have …

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 …

If you had less than one second to make a life-or-death decision to shoot a man who might be armed with a lethal weapon, what would you do? Would the ethnicity of the man affect your decision?

Could science ever make the clock move backwards? Experiments in quantum physics are showing that the future influences the present: what happens later limits the choices we think we have now.

Evolution say that all life exists only to reproduce; a new theory proposes that instead of passing on genes, humans have another purpose.

Our universe seems real. But what if it's a video game? Scientists in a variety of fields are taking seriously the possibility that we live in a virtual reality.
