Galaxie vznikly jen n\u011bkolik set milion\u016f let po vzniku vesm\u00edru. V t\u00e9 dob\u011b, p\u0159ed asi 13 miliardami let, byly galaxie mal\u00e9 a nach\u00e1zely se mnohem bl\u00ed\u017e u sebe. Sr\u00e1\u017eky byly b\u011b\u017en\u00e9. Jak se galaxie navz\u00e1jem sr\u00e1\u017eely, zv\u011bt\u0161ovaly se a m\u011bnily tvar.<\/p>\n

Od t\u00e9 doby se vesm\u00edr rozp\u00edn\u00e1. V\u011bt\u0161ina galaxi\u00ed se od sebe vzdaluje vysokou rychlost\u00ed, s v\u00fdjimkou galaxi\u00e1ln\u00edch shluk\u016f, kde se galaxie navz\u00e1jem ob\u00edhaj\u00ed.<\/p>","protected":false},"excerpt":{"rendered":"
