This one hour long lecture from Dr. Lawrence Krauss is simply a must-watch. Absolutely worth spending the time, especially if like to learn more about latest universe research results.
Lawrence Krauss is highly intelligent person with a great sense of humor, which you'll see in the video. The moments I enjoy the most are when he goes on explaining all those super-complex problems of astrophysics, writing numbers and greek letters all over the chalkboard, and when he's done explaining, he turns to the audience and says: "But we still don't know". Obviously all those years of research, study and calculations only brought them to "not-knowing". Genuine "not-knowing". Truth can only be experienced, it cannot be calculated or logically grasped. It cannot be put in to words. This I consider as a turning point That's when one is becoming meditative and starts looking inward.
Enjoy the show!!!
