Development of Cosmology: From a Static Universe to Accelerated Expansion

摘要: Within less than a century, our conception of the Universe has dramatically changed. While it was considered possible until 1920s that could be static and size Milky Way galaxy, we now have precise ideas on its age, evolution, geometry, contents way how structures may originated developed. Describing this rapid change world model is goal contribution. Beginning with Einstein’s theory General Relativity, I summarise evolution cosmological in parallel accumulation observational evidence. Cosmological expansion, age Universe, origin chemical elements, steady-state model, arguments for discovery relics hot beginning, dark matter cosmic are main items discussed. The essay ends inflation accelerated expansion.
