Machian Gravity: A mathematical formulation for Mach's Principle
Santanu Das
The general theory of relativity (GR) was proposed with an aim of incorporating Mach's principle mathematically. Despite early hopes, it became evident that GR did not follow Mach'…
Aspects of Everpresent (I): A Fluctuating Cosmological Constant from Spacetime Discreteness
Santanu Das, Arad Nasiri, Yasaman K. Yazdi
We provide a comprehensive discussion of the Everpresent cosmological model arising from fundamental principles in causal set theory and unimodular gravity. In this framework t…
Mach's principle and the origin of the quantum phenomenon
Santanu Das
Concept of inertial mass is not well defined in physics. For defining inertial mass of a particle we need to know its acceleration under some force in an inertial reference frame,…
Machian gravity and a cosmology without dark matter and dark energy
Santanu Das
The standard model of cosmology is based on the general theory of relativity and demands more than 95\% of the universe to consist of dark matter and dark energy that has no direct…
