Sensing the Inflationary Production of Scalars
A. J. Foraci, C. Litos, R. P. Woodard
We review the mechanism by which loops of matter fields contribute to the graviton self-energy during de Sitter inflation. This self-energy is used to quantum-correct the linearize…
A Nonlocal Realization of MOND that Interpolates from Cosmology to Gravitationally Bound Systems
C. Deffayet, R. P. Woodard
Nonlocal modifications of gravity derive from corrections to the quantum gravitational stress tensor which grow nonperturbatively strong during primordial inflation and may persist…
Resumming Photon Loops for Inflationary Gravity
A. J. Foraci, R. P. Woodard
A previous calculation of the 1-loop photon contribution to the graviton self-energy on de Sitter background is considered. We first show that there is no local obstacle to conserv…
Visions in Quantum Gravity
Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…
The Price of Abandoning Dark Matter Is Nonlocality
C. Deffayet, R. P. Woodard
We consider the classic question posed by Pardo and Spergel about the price of abandoning dark matter in the context of an invariant, metric-based theory of gravity. Our answer is…
How Far Are We from the Quantum Theory of Gravity?
R. P. Woodard
I give a pedagogical explanation of what it is about quantization that makes general relativity go from being a nearly perfect classical theory to a very problematic quantum one. I…
