You exist. You shouldn’t. Stars and galaxies and planets exist. They shouldn’t. The nascent universe contained equal parts matter and antimatter that should have instantly obliterated each other, turning the Big Bang into the Big Fizzle. And yet, here we are: flesh, blood, stars, moons, sky. Why? Come join us as we dive deep down the rabbit hole of solving the mystery of the missing antimatter.
MODERATOR: Brian Greene
PARTICIPANTS: Marcela Carena, Janet Conrad, Michael Doser, Hitoshi Murayama, Neil Turok
OPENING FILM: Animation by Eoin Duffy of Studio Belly, written by Justin Weinstein and Brian Greene

Electromagnetic Spectrum , a science documentary explaning forms of lightThe visible light that we see is just a small part of the actual light emitted throughout the universe. Through the combination of electrical and magnetic fields, light energy is produced. Nothing in the universe moves faster than the speed of light, which is 186,000 miles per second, or 670,000,000 miles per hour. Light travels in different wavelengths. The portion of light we see, referred to as visible light, shows up as the colors of the rainbow. These are red, orange, yellow, green, blue, indigo and violet. The other types of light in the spectrum, or the invisible light, are radio, microwave, infrared, ultraviolet, x-ray, and gamma ray. In this order, radio waves have the longest wavelength, while gamma rays have the shortest.Since all matter emits light, we can use infrared telescopes to see stars and dust in space that we would otherwise be unable to see. And by viewing the color of the star, we can gauge its distance and its temperature.
A second doesn't always feel like a second—time can seem to slow down if you're riding a death-defying roller coaster, or speed up while you're having a night out on the town. But just what's going on inside our heads to skew our perception of time? Neuroscientists Lila Davachi, Dean Buonomano, David Eagleman, and Kia Nobre discuss findings from the latest scientific investigations into the intricacies of our internal clocks in "The Deceptive Watchman," a program in the Big Ideas series at the 2014 World Science Festival.

Brought to you by www.excellent.org.uk. Lack of water is the biggest threat to the lives of people living in dryland Africa. In addition, soil erosion further threatens their ability to grow enough food to eat. In this short film, we expalin how communities work together to conserve soil and water to create true self-help development.
