A Brief History of Everything, feat. Neil deGrasse Tyson

We begin our story about 13.7 billion years ago, when all the space, matter, and energy of the known Universe was locked up in a volume less than one trillionth of the size of the point of a pen.

The Illusion of Time

Time. We waste it, save it, kill it, make it. The world runs on it. Yet ask physicists what time actually is, and the answer might shock you: They have no idea. Even more surprising, the deep sense we have of time passing from present to past may be nothing more than an illusion. How can our understanding of something so familiar be so wrong?

Where Am I

Where Am I? Is a new documentary about the skills we use to find our way around. Whether you are an Inuit hunter, a foraging insect, or just someone out for a stroll, your brain is performing one of its most fundamental services – it’s navigating. Why are some of us good at finding our way, while others are not? Good navigators are able to use both memory and imagination…remembering where they have been, and imagining where they’re going. Some researchers believe we build a cognitive or mental map when we navigate, a kind of bird’s eye view of our surroundings, a view that can be rotated and examined in our mind. There has been about sixty years of argument amongst scientists about whether humans and other mammals actually form these cognitive maps or not. The advent of GPS or Global Positioning Systems has changed the discussion about navigation. GPS triggers a simpler, more automatic navigational technique that does not involve building a mental map. With GPS, we simply respond to directions and may not truly understand where we are.

The fundamentals of space-time (Part 2)

Light always travels at a speed of 299,792,458 meters per second. But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible! In this second installment of a three-part series on space-time, CERN scientists Andrew Pontzen and Tom Whyntie use a space-time diagram to analyze the sometimes confounding motion of light.

How did the Universe Begin?

The human race has succeeded in explaining nearly everything in this universe using mathematical formulae. Yet there is one place that remains shrouded in mystery -– black holes. Physicists believe that if they could discover a formula that explains the center of black holes, the last remaining mystery of the universe could finally be unraveled -– how the universe came into being. Their attempts have been mired by unforeseen pitfalls but with the development of superstring theory, physicists have arrived at a formula that could finally end their century-long search. What the formula described was a world beyond our wildest imaginations. This is the incredible story of physicists like Einstein, Hawking and the superstring theorists who have endeavored to solve the mystery of the origin of the universe.
