Description
Three of the most important words in science are “I don’t know.” Not knowing implies a Universe of opportunities—the possibility of discovery and surprise. Our understanding of science has advanced immeasurably over the last five hundred years, yet many fundamental mysteries of existence persist: How did our Universe begin? How big is the Universe? Is time travel possible? What’s at the center of a black hole? How did life on Earth arise? Are we alone? What is consciousness, and can we create it?
