Evidence for the quantum birth of our Universe

Unnikrishnan, C. S; Gillies, G. T; Ritter, R. C (Indian Academy of Sciences, 2002-08)

We present evidence for a nonsingular origin of the Universe with initial conditions determined by quantum physics and relativistic gravity. In particular, we establish that the present temperature of the microwave background ...
Probing massive gravitons in f(R) with lensed gravitational waves

Sharma, Vipin Kumar; Harikumar, Sreekanth; Grespan, Margherita; Biesiada, Marek; Verma, Murli Manohar (Elsevier B.V Funded by SCOAP, 2024-12)

We investigate the novel features of gravitational wave solutions in f(R) gravity under proper gauge considerations in the shifted Ricci scalar background curvature (R1+ϵ). The solution is further explored to study the ...
What is Special About the Planck Mass?

Sivaram, C (South Asian Publishers Pvt Ltd, 2008-06)

Planck introduced his famous units of mass, length and time a hundred years ago. The many interesting facets of the Planck mass and length are explored. The Planck mass ubiquitously occurs in astrophysics, cosmology, quantum ...
