Item quasi-steady state cosmology(Wydawnictwa Uczelniane, 2001-06-20) Narlikar, J. V.This paper begin with a discussion of the shortcomings of standard cosmology, and then outlines an alternative cosmology called Quasi-Steady State Cosmology (QSSC). The theoretical framework and observational tests of the QSSC are next described. Finally some tests which can distinguish between the standard big bang cosmology and the QSSC are briefly mentioned.Item Quasi-steady state cosmology: some recent developments(Indian Academy of Sciences, 1997-03-13) Narlikar, J. V.This paper summarises the recent work on the quasi-steady state cosmology. This includes, the theoretical formulation and simple exact solutions of the basic equations, their relationship to observations, the stability of solutions and the toy model for understanding the growth of structures in the universe.Item Quasi-steady state cosmology(IOP Publishing, 1995-03-14) Hoyle, F.; Burbidge, G.; Narlikar, J. V.Because of a number of unsatisfactory features of the standard hot big bang cosmology, it is argued that there is a case for exploring alternative approaches to cosmology. The approach described here called the quasi steady state cosmology (QSSC, uses a field theoretic description of matter creation within the framework of general relativity. A cosmological solutions with the universe expanding exponentially along with cycles of expansion and contraction arises from mini-creation events taking place near the event horizons of highly collapsed massive objects. The now familiar phenomena like QSOs, AGN, radio sources etc. are the manifestations of matter creation in such events. In this way cosmology is seen to be related to high energy astrophysics in a very direct way. The quasi can explain the abundances of light nuclei and the microwave background, observed large scale features of the universe like the m-z relation, the source count, the angular size-redshift relation, as well as observed distribution of the ages of galaxies.Item Quasi-steady state cosmology(International Astronomical Union, 1994-03-12) Hoyle, F.; Burbidge, G.; Narlikar, J. V.Item Mach's principle and the creation of matter(Royal Society, 1963-04-23) Hoyle, F.; Narlikar, J. V.Accurate experiments have shown that the local inertial frame is the one with respect to which the distant parts of the universe are non-rotating. This coincidence, first noticed by Newton, later led to the ormulation of Mach's principle. It is known that relativity theory by itself cannot explain this coincidence. The introduction of a scalar 'creation field' into the theory is likely to improve the situation. Calculation shows that the continuous creation of matter has the effect of smoothing out any irregularities in the universe as itexpands, while rotation, if present, becomes less and less. This explains the observed remarkable degree of homogeneity and isotropy in the universe.Item Mach's principle and the creation of matter(Royal Society, 1962-11-27) Hoyle, F.; Narlikar, J. V.
