One hundred years ago humans first arrived at South Pole and for the past 20 or so years scientists have traveled there to build telescopes to study the early Universe. These experiments measure light left over from the Big Bang, the cosmic microwave background (CMB). They provide a unique snapshot of the infant Universe at a time when it was only ~400,000 years old, or 0.003% of its current age. These measurements and other evidence tell us that the Universe began with a Big Bang about 14 billion years ago, and that it contains only 4 percent "ordinary" matter (e.g., stars and galaxies, you and me, etc.). The rest of the Universe consists of two mysterious dark components: Dark Matter and Dark Energy. We will discuss evidence for the Big Bang, Dark Matter, and Dark Energy; the latest results from the South Pole, and what its like to work at the bottom of the world.
