Last fall, we featured a talk by the hot-shot theoretical physicist Lawrence Krauss, “A Universe from Nothing,” which answered some big enchilada questions: What is our current understanding of the universe? When did the universe begin? What came before it? How could something come from nothing? And what will happen to the universe in the future?
The lecture gave a snapshot of the thinking laid out in Krauss’ newly-released book by the same title: A Universe from Nothing: Why There Is Something Rather than Nothing. The book just hit the stands, and right now it’s #51 on the Amazon bestseller list. Not bad for a text that delves into the complex mysteries of dark matter, quantum mechanics and cosmology.
In case you missed the original lecture, we have posted “A Universe from Nothing” below for your viewing pleasure. (It has racked up over a million views on YouTube.) And you can catch the video trailer for Krauss’ new book right above. Find more great physics videos in our collection of Free Online Courses and Great Science Videos.
