2 Zero-order cosmology 2 1 The FLRW metric The FLRW metric is d?2 = dt 2 a(t) dr2 1 kr2 + r2d 2 + r2 sin2 d?2 : = dt 2 a(t) dr2 1 kr2 + d 2 ; where k= 0; 1 and, if k= 1, ris bounded Hubble noticed that objects seemed to recede at velocity proportional to their distance (There were all kinds of problems with his paper, but he was right in

Cosmology On occasion I refer back to that book (cited here as “G&C”) for material that does not seem worth repeating here Classical general relativity has not changed much since 1972 (apart from a great strengthen-ing of its experimental veri?cation) so it did not seem necessary to cover gravitation as well as cosmology in the present

of inflationary cosmology, which draws on a blend of concepts from particle physics and gravitation The last few years have been a remarkably exciting time for cosmology, with new observations of unprecedented accuracy yielding many surprises Einstein_s legacy is flourishing in the early 21st century Inflation was invented a quarter of a century
