We ask some of the world’s top thinkers in science, astronomy, technology, academia and futurism to ponder some of our most popular What If videos. What If half the Earth’s population was wiped out? What If you fell into a pool of liquid nitrogen? What If we lived in a Galactic Zoo? What If we are living in a simulation? What if we Settled on the Moon? What if we became Cyborgs? What If we discovered Alien Life? What If you lived 50 years into the future?
