OUR UNIVERSE : AN EXPANDING MYSTERY Supratik Pal Indian Statistical Institute, Kolkata
Night Sky From New York
Supernova Anisotropy Probe Wilkinson Microwave Anisotropy Probe
Our Galaxy Milky Way
How far are They ? 4 Light Years = (300000 km/sec) X (4X365X24X60X60 sec) = 40000000000000 kilo-meters !!! Nearest Galaxy Our Galaxy
What do they tell us ? Age of the Universe = 13800000000 Years Size of our Universe = 13800000000 Light Years = 100000000000000000000000 kilo-meters !!! Why are they so important ?
And miles to go • Dark energy or cosmological constant? • What is dark energy? • Why is cosmological constant so small? • What is dark matter? • Who governs fast expansion at the beginning? • How were stars, galaxies etc formed? • Gravitational waves: yes or no? • How to match precise observational data? • How to discriminate a model from others? • Many more…..
