# Dark Matter: Introduction

@article{Rees2004DarkMI, title={Dark Matter: Introduction}, author={Martin J. Rees}, journal={arXiv: Astrophysics}, year={2004} }

This short review was prepared as an introduction to the Royal Society's 'Dark Matter' conference. It addresses the embarrassing fact that 95% of the universe is unaccounted for. Favoured dark matter candidates are axions or weakly-interacting particles that have survived from the very early universe, but more exotic options cannot be excluded. Experimental searches are being made for the 'dark' particles but we have indirect clues to their nature too. Comparisons of data (from, eg…

On the Nature of Dark Matter and Dark Energy

- Physics
- 2010

It is known that all candidates in dark matter (DM) particles (neutrinos, axions, supersymmetric particles etc.) can not explain the basic properties of DM. The same can be said on the proposed…

Dark matter, dark energy and modern cosmology: the case for a Kuhnian paradigm shift

- Physics, Philosophy
- 2008

Several works in the last few years devoted to measure fundamental probes of contemporary cosmology have suggested the existence of a delocalized dominant component (the "dark energy"), in addition…

Spin-half fermions with mass dimension one: theory, phenomenology, and dark matter

- Physics, Mathematics
- 2005

We provide the first details on the unexpected theoretical discovery of a spin-one-half matter field with mass dimension one. It is based upon a complete set of dual-helicity eigenspinors of the…

Ultra High Energy Cosmic Rays from decays of Holeums in Galactic Halos

- Physics

Stable, quantized gravitational bound states of primordial black holes called Holeums could have been produced in the early universe and could be a component of the Super Heavy Dark Matter (SHDM)…

Quintessential Inflation, Unified Dark Energy and Dark Matter, and Higgs Mechanism

We describe a new type of gravity-matter models where gravity couples in a non-conventional way to two distinct scalar fields providing a unified Lagrangian action principle description of: (a) the…

Wheeler-DeWitt Quantization of Gravity Models of Unified Dark Energy and Dark Matter

- Physics

First, we describe the construction of a new type of gravity-matter models based on the formalism of non-Riemannian space-time volume forms - alternative generally covariant integration measure…

Unified Dark Energy-Dark Matter model with Inverse Quintessence

- Physics
- 2012

We consider a model where both dark energy and dark matter originate from the coupling of a scalar field with a non-canonical kinetic term to, both, a metric measure and a non-metric measure. An…

Quantum Celestial Mechanics: Large-scale Gravitational Quantization States in Galaxies and the Universe

- Physics

We report a new theory of celestial mechanics for gravitationally bound systems based upon a gravitational wave equation derived from the general relativistic Hamilton‐Jacobi equation. The single ad…

Metric-Independent Spacetime Volume-Forms and Dark Energy/Dark Matter Unification

- Physics
- 2015

The method of non-Riemannian (metric-independent) spacetime volume-forms (alternative generally-covariant integration measure densities) is applied to construct a modified model of gravity coupled to…

Quintessence, Unified Dark Energy and Dark Matter, and Confinement/Deconfinement Mechanism

- Physics
- 2018

We describe a new type of generalized gravity-matter models where $f(R)=R+R^2$ gravity couples in a non-conventional way to a scalar "inflaton" field, to a second scalar "darkon" field responsible…
