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!
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.
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.
Quantum theory, the best explanation of how atoms and anything smaller behave, is so weird even scientists who have mastered it find it baffling. But bit by bit scientists are finding maybe it's not so weird as comparable behavior is discovered in our every day world. It's just that no one noticed before.
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 email. Could brain hackers someday be able to rewrite our thoughts?
Our universe seems real. But what if it’s a videogame? Scientists in a variety of fields are taking seriously the possibility that we live in a virtual reality. Maybe the Big Bang was just the moment someone flipped the switch and turned on our universe. Maybe what looks random has already been programmed to happen. If some advanced civilization did design and program our universe, would we ever know? Scientists are looking for glitches in the laws of the universe that may uncover its hidden code.
Death is life's greatest certainty. But that may be about to change. Scientists have discovered an immortal animal that may hold the secret of endless regeneration. They're on the brink of editing our DNA so that we can cure death like a disease. Or is dying necessary for the survival of our species?

Every 17 minutes in America, someone is killed with a gun. Politicians can't seem to stop the violence. But epidemiologists, psychologists and big data crunchers are discovering that gun crime spreads like a virus -and science may be able to stop its spread.

Physicist Dr Helen Czerski takes us on an amazing journey into the science of bubbles. Bubbles may seem to be just fun toys, but they are also powerful tools that push back the boundaries of science. The soap bubble with its delicate, fragile skin tells us about how nature works on scales as large as solar system and as small as a single wavelength of light. Then there are underwater bubbles, which matter because they are part of the how the planet works. Out at sea, breaking waves generate huge plumes of bubbles which help the oceans breathe. From the way animals behave to the way drinks taste, Dr Czerski shows how bubbles affect our world in all sorts of unexpected ways. Whether it's the future of ship design or innovative new forms of medical treatment, bubbles play a vital role.

Mysteries of the Unseen World transports audiences to places on this planet that they have never been before, to see things that are beyond their normal vision, yet literally right in front of their eyes. Mysteries of the Unseen World reveals phenomena that can't be seen with the naked eye, taking audiences into earthly worlds secreted away in different dimensions of time and scale. Viewers experience events that unfold too slowly for human perception; They "see" the beauty, drama, and even humor of phenomena of that occur in the flash of a microsecond; They enter the microscopic world that was once reserved only for scientists, but that Mysteries of the Unseen World makes accessible to the rest of us; They begin to understand that what we actually see is only a fraction of what there is TO see on this Earth. High-speed and time-lapse photography, electron microscopy, and nanotechnology are just a few of the advancements in science that now allow us to see a whole new universe of things, events, creatures, and processes we never even knew existed and now give us new "super powers" to see beyond what is in front of us. Visually stunning and rooted in cutting-edge research, Mysteries of the Unseen World will leave audiences in complete thrall as they begin to understand the enormity of the world they can't see, a world that exists in the air they breathe, on their own bodies, and in all of the events that occur around them minute-by-minute, and nanosecond-by-nanosecond. And with this understanding comes a new appreciation of the wonder and possibilities of science.
