As Thanksgiving approaches, take a minute to ponder this: some expansion is inevitable. But it isn't just your waistline that is growing. 10 years ago scientists discovered a dark energy that is pushing the universe outwards at increasing speeds. Tonight, get to the meat of one of the biggest physics quandaries of the 21st century with Dr. Eric Linder of Berkeley Labs. Starting at 5:30 p.m., Linder will discuss how dark energy has been linked to supernovas and dinosaur extinction at the Berkeley Repertory Theater. More interested in the dark forces cramping your networking skills? The Executive Sandbox will be discussing the essential communication skills to help you build rapport with clients and bosses at Patima Organic Coffee from 6:30 - 8:30 p.m. (Photo by Erin O'Connor)
