Have advanced aliens discovered everything there is to know about the universe, or are they, too, looking for answers? The answer may lie buried on Earth. 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 understanding of the laws of nature and the human brain. Are the wealthy born in the right place at the right time?
Are the poor victims of a system designed to keep them down? Do physics and biology determine who is rich and who is poor? Throughout history, distribution of wealth is governed by hidden forces. There could be an undiscovered species unlike anything we've ever known - the ocean. Its body spans thousands of miles; its heart beats with a one-thousand-year pulse.
It could even have an immune system capable of annihilating all other life on earth. It is a nightmare that has stalked us for centuries: hordes of human beings transformed into mindless, cannibalistic monsters. Could this nightmare become reality? Neuroscientists are discovering how easy it is to lose conscious control of our bodies. 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. This program delves deep into the atom to find the ultimate constituents of matter focusing finally on the theoretical Higgs Boson. S1, Ep8. Scientists have discovered that the universe we see is an incidental component of all there is. This program explains how dark matter and dark energy were discovered and how scientists are struggling to understand them.

And we'll probe the biggest question about time: Is our future determined? Do we exercise free will? Or, is time merely a dream? 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? 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? 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.
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. 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. 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? 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. 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 start of a great future is uncertain.
How different are the races? Is there even such a thing as race? Could technology create a superior race? The answer may tell us where humanity is headed, what our descendants will look like and how they will think. As scientists peer across the galaxy, a new revelation emerges: The universe is shockingly organic. Are the secrets to the life and death of the universe hidden not in physics, but biology? Could it be that the universe is alive? What is it that makes you you? Scientists are searching the brain for the core of who we are - some would call it the soul, others, our personal identity.
How do we become who we are? Is empty space really empty? Scientists regard understanding the true nature of empty space may explain where the universe came from, whether it is fated to expand into oblivion or whether it will undergo another dramatic transformation that could destroy everything we know.
With cloning and genetic engineering, we can bring back extinct animals. But could we also bring back dead humans? Is it possible to keep our brains alive after our bodies have died? Could we rise from the dead in some strange new form?
Can we - should we - resurrect the dead? What drives some to torture and kill without remorse? Why do seemingly normal people commit acts of cruelty and violence. Researchers are exploring our inner demons, looking for ways to isolate and neutralize the source of evil in the brain.
Is it really possible to change human nature? 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 people healthier and more creative. There are also dangers lurking in the dark recesses of the mind. 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 disappear.
Some may hope for eternity, but the possibility of never-ending time has mind-bending implications for the present. 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? 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-depth discussion of the Higgs field and mass.
We can all trace our lives back to a beginning. But what defines the beginning? Is it the moment when two cells unite? Or does something have to know it is alive before its life can begin?
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 holocaust. Everything we know will turn to hot, bubbling, plasma. If the stuff of life is spread throughout the cosmos, then the universe could be teeming with aliens. Will alien brains think in ways we understand?
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.
