Dark Energy
TLDR
Dodelson et al. as discussed by the authors showed that the universe is so much bigger than the bit we can see in our observable bubble and we know nothing about what lies out there in the cosmos.Abstract:
The universe is so much bigger than the bit we can see in our observable bubble and we know nothing about what lies out there in the cosmos. The challenge is so much bigger than is shown on this chart and it is evident that we really only understand a tiny fraction of the whole cosmos. Theories for Dark Energy have been around for a long time but we still have no satisfactory explanation. None of the theories are adequate, some are clearly wrong – an error of 10^120 is a really big miss! Scott Dodelson of Carnegie Mellon University, one of the lead scientists behind the Dark Energy Survey’s new map of cosmic structure says:read more

TL;DR: The role of torsion in gravity has been extensively investigated along the main direction of bringing gravity closer to its gauge formulation and incorporating spin in a geometric description, and various torsional constructions, from teleparallel, to Einstein-Cartan, and metric-affine gauge theories are reviewed.
Journal ArticleDOI
Beyond the Cosmological Standard Model
TL;DR: A review of the current state of the field and a framework for anticipating developments in the next decade can be found in this paper, where the authors identify the guiding principles for rigorous and consistent modifications of the standard model, and discuss the prospects for empirical tests.

De Sitter Space and the Swampland
TL;DR: In this article, the authors proposed a swampland criterion for the existence of a meta-stable de Sitter (dS) vacuum in string theory, for a scalar potential of any consistent theory of quantum gravity.
Journal ArticleDOI
Black holes in scalar-tensor gravity.
TL;DR: It is extended that black holes which are stationary as the end point of gravitational collapse in Brans-Dicke theory are no different than in general relativity to the much more general class of scalar-tensor and f(R) gravity theories, without assuming any symmetries apart from stationarity.
Journal ArticleDOI
WIMP dark matter candidates and searches - current issues and future prospects
TL;DR: In this article, the authors review several current aspects of dark matter theory and experiment, including current bounds and recent claims and hints of a possible signal in a wide range of experiments: direct detection in underground laboratories, gamma-ray, cosmic ray, X-ray and neutrino telescopes, and the LHC.
