Lecture Date: Tuesday, October 30, 2007. What is the Universe made of? This question has been asked as long as humans have been questioning, and astronomers and physicists are finally converging on an answer. The picture which has emerged from numerous complementary observations over the past decade is a surprising one: most of the matter in the Universe isn't visible, and most of the Universe isn't even made of matter. In this talk, I will explain what the rest of this stuff, known as "Dark Energy" is, how it is related to the so-called "Dark Matter", how it impacts the evolution of the Universe, and how we can study the dark universe using observations of light from current and future telescopes. Lecturer: Risa Wechsler, SLAC National Accelerator Laboratory.

Is the creation story of Genesis 1 compatible with modern science? Does a literal reading of the text show remarkable knowledge of future discoveries? Or, must the text be reinterpreted to align it with today's scientific discoveries? In this video series, we examine Genesis 1 in light of modern science. We take a detailed look at each verse and compare it with the findings of physics, cosmology, biology and other scientific fields. We examine the book as it was plainly written, as creationists like Ken Ham and Kent Hovind approach the text. We will also look at fresh interpretations of the text from authors like Andrew Parker and Gerald L. Schroeder and see if we can discover any hidden scientific knowledge in the chapter. Or, will we merely uncover what Genesis got wrong?
