Modeling Repulsive Gravity with Creation
R. G. Vishwakarma, J. V. Narlikar
There is a growing interest in the cosmologists for theories with negative energy scalar fields and creation, in order to model a repulsive gravity. The classical steady state cosm…
Comments on "Dark matter: A phenomenological existence proof"
R. G. Vishwakarma
A recent paper by Ahluwalia-Khalilova (astro-ph/0601489) is examined where he claims that the standard FRW cosmology with a predicts existence of dark matter without invoking t…
Do recent supernovae Ia observations tend to rule out all the cosmologies?
Ram Gopal Vishwakarma
Dark energy and the accelerated expansion of the universe have been the direct predictions of the distant supernovae Ia observations which are also supported, indirectly, by the ob…
In Quest of a True Model of the Universe
R. G. Vishwakarma
While many observations support the validity of Einstein's general relativity as the theory of gravity, there are yet many that suggest the presence of new physics. In order to exp…
Inhomogeneities in the Microwave Background Radiation interpreted within the framework of the Quasi-Steady State Cosmology
J. V. Narlikar, R. G. Vishwakarma, Amir Hajian +3
We calculate the expected angular power spectrum of the temperature fluctuations in the microwave background radiation (MBR) generated in the quasi-steady state cosmology (QSSC). T…
Can brane cosmology with a vanishing Λexplain the observations?
R. G. Vishwakarma, Parampreet Singh
A plethora of models of the universe have been proposed in recent years claiming that the present universe is accelerating, being driven by some hypothetical source with negative p…
