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 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.

The Nazis knew it was their last chance. The British knew it was the deadliest threat they'd ever face. And the Americans knew it could fall into the wrong hands. The V2 rocket quickly became Hitler's greatest deadly weapon and beacon of hope to turn the course of World War II in his favor. Watch Nazi Germany's desperate attempt at victory as the Allies race to stop them and see how the V2 miraculously went from deadly weapon to amazing feat of space technology.

After years of anticipation, autonomous vehicles are now being tested on public roads around the world. As ambitious innovators race to develop what they see as the next high-tech pot of gold, some experts warn there are still daunting challenges ahead, including how to train artificial intelligence to be better than humans at making life-and-death decisions. How do self-driving cars work? How close are we to large-scale deployment of them? And will we ever be able to trust AI with our lives?
Learn about the technologies that will usher in a whole new way of life: we will live in floating cities, fly to work and travel in cars capable of operating underwater. And, with new technologies, humanity will find new ways of protecting and conserving resources to meet the needs of a growing population by using renewable sources of water, food and electricity. The era of smog-filled skies will be over, because fewer of us will be driving cars. Where we’re going, we won’t need roads. We’ll be piloting environmentally friendly personal vehicles between cities and under the seas. And the good news is we’ll never be lost, thanks to new advances in GPS-driven virtual mapping. Then again, with the ability to teleport our presence anywhere on Earth, we might not have to travel at all. And, best of all, we’ll all have more time to enjoy the astounding advances of our near future, because we’ll all be living longer. A lot longer.
To respond to global demand and population growth, energy production will have to increase by 75% between now and 2050. The fossil fuels (oil, coal and natural gas) that we use currently use on a massive scale are becoming increasingly rare and are highly polluting, wreaking havoc on the climate.
