How did a smooth Big Bangmake complicated things like us?• Gravity is long range attractive force– Matter distribution is unstable• Remove heat, and system heats up more• Makes condensed objects (stars, galaxies, etc.)• Gravitational energy flows support complexity• Stars release heat from nuclear reactions– Heat & light received by Earth supportcomplexity, from weather to photosynthesisOct. 13, 2008 Mather Munich 2008 14
Brief History of the UniverseBig Bangseen byCOBE &WMAP?Galaxyassembly?Galaxies,stars,planets,life• Horrendous Space Kablooey - exponential expansion, primordial fluctuations,matter/antimatter, dark matter, dark energy, 13.7 ± 0.2 billion years ago• Annihilation of antiparticles, 1 part per billion matter remaining• Formation of Helium nuclei, 3 minutes, redshift z = 10 9– [1+z = size of universe now / size then]• Formation of neutral gas “recombination”, 389,000 yrs, z=1089• Population III supermassive stars, super-supernovae, and black holes, z=17(age ~ 200 Myr)• Galaxy formation in small parts, star formation, merging and clustering ofgalaxy parts, until z~1• Expanding universe begins to accelerate, 5 billion years ago• Earth and Sun form, 4.5 billion years ago• Mammals dominant, ~ 55 million years ago• Humans, lions, tigers, mammoths, 1-2 million years ago• Telescopes, Galileo, 1609: ~ 400 yr• Theory of Special Relativity, 100 yr• NASA founded, Oct. 1, 1958• Signs of life on other planets …?• Far future: we’re toast (1 billion yrs)• Andromeda Nebula collides with Milky Way (5 billion years)• Sun goes out (7.6 billion years)• Universe continues to expand faster, we lose sight of other galaxies• Universe goes dark?Oct. 13, 2008 Mather Munich 200815
