Abstra act Co osmologicaal inflation n is a propposal that for a while, very eaarly in its h history, the Universe expanded d (almost ) exponen ntially fast. This coould explaain why the Universe is so large e and has not (yet) collapsed. Inflation can also explain whyy the Universe is so homogenneous and d isotropicc on very large scales, and whyy its geometry is (alm most) flat . Moreove er, quantu um effectss during in nflation the strucctures see coulld have generated g en in the Universee today, such s as galaxies and clusters. Measurem ments of the t cosmic microw wave background are probing models of inflatiion, and may sho ow us hhow to connect c them m with particle physsics, quantum graviity and perhaps stri ng theoryy.
