A Non-Singular Cyclic Universe from Modified Gravity
Saurya Das, Mitja Fridman, Dhiraj Kuniyal +1
The Big Bang singularity marks a fundamental breakdown of General Relativity, yet all proposed quantum gravitational remedies invoke microphysical assumptions beyond the observatio…
A novel violation of the equivalence principle
Saurya Das, Mitja Fridman, Sourav Sur
It is generally assumed that any discrepancy between an object's inertial and gravitational masses, leading to a violation of the equivalence principle, arises from the nature of i…
A singularity free classical theory of gravity
Saurya Das, Mitja Fridman, Sourav Sur
We present a classical theory of gravity, which is singularity free at short distances and reduces to General Relativity at large distances. We discuss its implications.
Varying Newton's constant: a cure for gravitational maladies?
Saurya Das, Sourav Sur
We show that a slowly varying Newton's constant, consistent with existing bounds, can potentially explain a host of observations pertaining to gravitational effects or phenomena ac…
Gravitational lensing and missing mass
Saurya Das, Sourav Sur
The mass of an astrophysical object can be estimated by the amount of gravitational lensing of another object that it causes. To arrive at the estimation however, one assumes the v…
Emergent gravity at all scales
Saurya Das, Sourav Sur
It has recently been shown that any observed potential can in principle be generated via quantum mechanics using a suitable wavefunction. In this work, we consider the concrete exa…
