2 Max Tegmark University of Pennsylvania Max Tegmark University of Pennsylvania MEASURING THE UNIVERSE

3 Max Tegmark Univ. of Pennsylvania Campos de Jordão September 2,2002 Who cares? WHO CARES ABOUT COSMOLOGY? Particle physicists: - Is there dark matter? Massive neutrinos, wimps, axions or something else? - Did inflation happen? Can we learn about physics at very high energies? General relativists: - Did inflation produce gravity waves? - What is the geometry of the Universe? Numerical simulators: - Only need to run the code once, not for umpteen cosmological models People on the street - Will there be a big crunch? - How did it all begin? - Are there infinitely many other stars? Observers: - What is the correct age, distance and size for the objects being studied?

LECTURE 2: Cosmic microwave background: The basics of acoustic oscillations, how different cosmological parameters affect the CMB, summary of current and upcoming experiments. LECTURE 3: Galaxy clustering: The basics of structure formation, how different cosmological parameters affect the matter power spectrum P(k), summary of current and upcoming galaxy surveys. LECTURE 4: Other cosmological probes, outlook: Gravitational lensing, Lyman alpha forest, supernovae Ia, latest constraints on cosmological parameters, open questions, my speculations about what will be exciting areas for future research.
