    Alternative cosmologies
    (Dordrecht, D. Reidel Publishing Co., 1987-04-12) Narlikar, J. V.
    This review highlights some of the cosmological theories proposed as alternatives to the standard hot big bang model. Specific ideas discussed here are the matter-antimatter symmetric cosmologies, the empirical two-component model, the G-varying cosmologies, the chronometric cosmology and a simplified quantum cosmology. It is argued that many alternative cosmologies have contributed useful concepts and offered observational tests that have enriched the field of cosmology as a science.

    Mach’s principle
    (2011-04-10) Narlikar, J. V.
    The underlying idea in Mach's principle is that the origin of inertia or mass of a particle is a dynamical quantity determined by the environment, in particular the rest of the matter in the universe. In this article, we discuss the role of this idea in the Brans {Dicke theory of gravitation and the Hoyle {Narlikar cosmology.

    Role of a virtual library in the coming decades
    (ASP Conference Series, 2010-03-30) Narlikar, J. V.
    This paper consists of the keynote address presented by Dr. Narlikar, distinguished and renowned scholar and founder-director of the Inter-University Centre for Astronomy and Astrophysics. Dr. Narlikar critically examines the nature of library and information centers of the past and future through anecdote, example, and philosophical examination. He discusses the synergies between astronomical research and library science, speculates on the future of authenticity in a web-based environment and describes the futuristic “virtual library.”

    Cosmology and the origin of nuclei
    (2010-04-06) Narlikar, J. V.
    The problem of explaining the origin of all the chemical elements found in the universe is a central problem in astrophysics. In the 1940s Fred Hoyle suggested that they were cooked inside stars, starting with nucleosynthesis of neutrons and protons. In the same decade George Gamow argued that in a hot big bang universe in the first few minutes, the ambient conditions were suitable for formation of nuclei. This paper will review the progress of both these ideas and show that a reasonable compromise between these ideas can be found today.
