A Unifying Theory of Dark Energy and Dark Matter: Negative Masses and Matter Creation Within a Modified ΛCDM Framework J
Astronomy & Astrophysics manuscript no. theory_dark_universe_arxiv c ESO 2018 November 5, 2018 A unifying theory of dark energy and dark matter: Negative masses and matter creation within a modified ΛCDM framework J. S. Farnes1; 2 1 Oxford e-Research Centre (OeRC), Department of Engineering Science, University of Oxford, Oxford, OX1 3QG, UK. e-mail: [email protected]? 2 Department of Astrophysics/IMAPP, Radboud University, PO Box 9010, NL-6500 GL Nijmegen, the Netherlands. Received February 23, 2018 ABSTRACT Dark energy and dark matter constitute 95% of the observable Universe. Yet the physical nature of these two phenomena remains a mystery. Einstein suggested a long-forgotten solution: gravitationally repulsive negative masses, which drive cosmic expansion and cannot coalesce into light-emitting structures. However, contemporary cosmological results are derived upon the reasonable assumption that the Universe only contains positive masses. By reconsidering this assumption, I have constructed a toy model which suggests that both dark phenomena can be unified into a single negative mass fluid. The model is a modified ΛCDM cosmology, and indicates that continuously-created negative masses can resemble the cosmological constant and can flatten the rotation curves of galaxies. The model leads to a cyclic universe with a time-variable Hubble parameter, potentially providing compatibility with the current tension that is emerging in cosmological measurements. In the first three-dimensional N-body simulations of negative mass matter in the scientific literature, this exotic material naturally forms haloes around galaxies that extend to several galactic radii. These haloes are not cuspy. The proposed cosmological model is therefore able to predict the observed distribution of dark matter in galaxies from first principles. -
The Algebra of Grand Unified Theories
The Algebra of Grand Unified Theories John Baez and John Huerta Department of Mathematics University of California Riverside, CA 92521 USA May 4, 2010 Abstract The Standard Model is the best tested and most widely accepted theory of elementary particles we have today. It may seem complicated and arbitrary, but it has hidden patterns that are revealed by the relationship between three ‘grand unified theories’: theories that unify forces and particles by extend- ing the Standard Model symmetry group U(1) × SU(2) × SU(3) to a larger group. These three are Georgi and Glashow’s SU(5) theory, Georgi’s theory based on the group Spin(10), and the Pati–Salam model based on the group SU(2)×SU(2)×SU(4). In this expository account for mathematicians, we ex- plain only the portion of these theories that involves finite-dimensional group representations. This allows us to reduce the prerequisites to a bare minimum while still giving a taste of the profound puzzles that physicists are struggling to solve. 1 Introduction The Standard Model of particle physics is one of the greatest triumphs of physics. This theory is our best attempt to describe all the particles and all the forces of nature... except gravity. It does a great job of fitting experiments we can do in the lab. But physicists are dissatisfied with it. There are three main reasons. First, it leaves out gravity: that force is described by Einstein’s theory of general relativity, arXiv:0904.1556v2 [hep-th] 1 May 2010 which has not yet been reconciled with the Standard Model. -
Engineering the Quantum Foam
Engineering the Quantum Foam Reginald T. Cahill School of Chemistry, Physics and Earth Sciences, Flinders University, GPO Box 2100, Adelaide 5001, Australia [email protected] _____________________________________________________ ABSTRACT In 1990 Alcubierre, within the General Relativity model for space-time, proposed a scenario for ‘warp drive’ faster than light travel, in which objects would achieve such speeds by actually being stationary within a bubble of space which itself was moving through space, the idea being that the speed of the bubble was not itself limited by the speed of light. However that scenario required exotic matter to stabilise the boundary of the bubble. Here that proposal is re-examined within the context of the new modelling of space in which space is a quantum system, viz a quantum foam, with on-going classicalisation. This model has lead to the resolution of a number of longstanding problems, including a dynamical explanation for the so-called `dark matter’ effect. It has also given the first evidence of quantum gravity effects, as experimental data has shown that a new dimensionless constant characterising the self-interaction of space is the fine structure constant. The studies here begin the task of examining to what extent the new spatial self-interaction dynamics can play a role in stabilising the boundary without exotic matter, and whether the boundary stabilisation dynamics can be engineered; this would amount to quantum gravity engineering. 1 Introduction The modelling of space within physics has been an enormously challenging task dating back in the modern era to Galileo, mainly because it has proven very difficult, both conceptually and experimentally, to get a ‘handle’ on the phenomenon of space. -
– 1– LEPTOQUARK QUANTUM NUMBERS Revised September
{1{ LEPTOQUARK QUANTUM NUMBERS Revised September 2005 by M. Tanabashi (Tohoku University). Leptoquarks are particles carrying both baryon number (B) and lepton number (L). They are expected to exist in various extensions of the Standard Model (SM). The possible quantum numbers of leptoquark states can be restricted by assuming that their direct interactions with the ordinary SM fermions are dimensionless and invariant under the SM gauge group. Table 1 shows the list of all possible quantum numbers with this assumption [1]. The columns of SU(3)C,SU(2)W,andU(1)Y in Table 1 indicate the QCD representation, the weak isospin representation, and the weak hypercharge, respectively. The spin of a leptoquark state is taken to be 1 (vector leptoquark) or 0 (scalar leptoquark). Table 1: Possible leptoquarks and their quan- tum numbers.

The Pati-Salam model [4] is an example predicting the existence of a leptoquark state. In this model a vector lepto- quark appears at the scale where the Pati-Salam SU(4) “color” gauge group breaks into the familiar QCD SU(3)C group (or CITATION: S. -
Thermodynamics of Exotic Matter with Constant W = P/E Arxiv:1108.0824
Thermodynamics of exotic matter with constant w = P=E Ernst Trojan and George V. Vlasov Moscow Institute of Physics and Technology PO Box 3, Moscow, 125080, Russia October 25, 2018 Abstract We consider a substance with equation of state P = wE at con- stant w and find that it is an ideal gas of quasi-particles with the wq energy spectrum "p ∼ p that can constitute either regular matter (when w > 0) or exotic matter (when w < 0) in a q-dimensional space. Particularly, an ideal gas of fermions or bosons with the en- 4 3 ergy spectrum "p = m =p in 3-dimensional space will have the pres- sure P = −E. Exotic material, associated with the dark energy at E + P < 0, is also included in analysis. We determine the properties of regular and exotic ideal Fermi gas at zero temperature and derive a low-temperature expansion of its thermodynamical functions at fi- nite temperature. The Fermi level of exotic matter is shifted below the Fermi energy at zero temperature, while the Fermi level of regular matter is always above it. The heat capacity of any fermionic sub- stance is always linear dependent on temperature, but exotic matter has negative entropy and negative heat capacity. 1 Introduction arXiv:1108.0824v2 [cond-mat.stat-mech] 4 Aug 2011 The equation of state (EOS) is a fundamental characteristic of matter. It is a functional link P (E) between the pressure P and the energy density E. Its knowledge allows to predict the behavior of substance which appears in 1 various problems in astrophysics, including cosmology and physics of neutron stars. -

Teleportation
TELEPORTATION ESSAY FOR THE COURSE QUANTUM MECHANICS FOR MATHEMATICIANS ANNE VAN WEERDEN SUPERVISOR DR B.R.U. DHERIN UTRECHT UNIVERSITY JUNE 2010 PREFACE The aim of this essay is to describe the teleportation process in such a way that it will be clear what is done so far, and what is still needed, to develop a teleportation device for humans, which would be my ultimate goal. However much is done already, there are thresholds that still have to be overcome, some of which will need real ingenuity, and others brute computing power, far more than we are now capable of. But I will show why I have confidence that we will reach this goal by describing the astonishing developments in the field of teleportation and the speed with which computing, or technology, evolves. The discovery that teleportation really is possible came about while I was in my thirties, but I was largely unaware of its further developments until I started the research for this essay. Assuming that I am not the only one who did not know, I wrote this essay aimed at people from my age, in their fifties, who, like me, started out without television and computer, I even remember my Mother telling me how she bought a transistor radio for the first time, placed it in a closet and closed the door, just to be amazed that it could still receive signals and play. We saw it all come by, from the first steps on the Moon watched on the television my parents had only bought a few years earlier, I clearly remember asking my Father who, with much foresight, got us out of our beds despite my -
Can Mass Be Negative?
Can Mass Be Negative? Vladik Kreinovich1 and Sergei Soloviev2 1Department of Computer Science University of Texas at El Paso El Paso, TX 7996058, USA [email protected] 2Institut de Recherche en Informatique de Toulouse (IRIT) IRIT, porte 426 118 route de Narbonne 31062 Toulouse cedex 4, France [email protected] Abstract Overcoming the force of gravity is an important part of space travel and a significant obstacle preventing many seemingly reasonable space travel schemes to become practical. Science fiction writers like to imagine materials that may help to make space travel easier. Negative mass { supposedly causing anti-gravity { is one of the popular ideas in this regard. But can mass be negative? In this paper, we show that negative masses are not possible { their existence would enable us to create energy out of nothing, which contradicts to the energy conservation law. 1 Formulation of the Problem Overcoming the force of gravity is an important part of space travel and a significant obstacle preventing many seemingly reasonable space travel schemes to become practical. Science fiction writers like to imagine materials that may help to make space travel easier. Negative mass { supposedly causing anti- gravity { is one of the popular ideas in this regard. But can mass be negative? 2 Reminder: There Are Different Types of Masses To properly answer the question of whether negative masses are possible, it is important to take into account that there are, in principle, three types of masses: 1 • inertial mass mI that describes how an object reacts to a force F : the object's acceleration a is determined by Newton's law mI · a = F ; and • active and passive gravitational mass mA and mP : gravitation force ex- erted by Object 1 with active mass m on Object 2 with passive mass m · m A1 m is equal to F = G · A1 P 2 ; where r is the distance between the P 2 r2 two objects; see, e.g., [1, 3]. -

Introduction Time is mysterious. Philosophers and scientists have pondered the question of what time might be for centuries and yet till this day, we don’t know what it is. Everyone talks about time, in fact, it’s the most common noun per the Oxford Dictionary. It’s in everything from history to music to culture. Despite time’s mysterious nature there are a lot of things that we can discuss in a logical manner. Time travel on the other hand is even more mysterious. -
Negative Matter, Repulsion Force, Dark Matter, Phantom And
Negative Matter, Repulsion Force, Dark Matter, Phantom and Theoretical Test Their Relations with Inflation Cosmos and Higgs Mechanism Yi-Fang Chang Department of Physics, Yunnan University, Kunming, 650091, China (e-mail: [email protected]) Abstract: First, dark matter is introduced. Next, the Dirac negative energy state is rediscussed. It is a negative matter with some new characteristics, which are mainly the gravitation each other, but the repulsion with all positive matter. Such the positive and negative matters are two regions of topological separation in general case, and the negative matter is invisible. It is the simplest candidate of dark matter, and can explain some characteristics of the dark matter and dark energy. Recent phantom on dark energy is namely a negative matter. We propose that in quantum fluctuations the positive matter and negative matter are created at the same time, and derive an inflation cosmos, which is created from nothing. The Higgs mechanism is possibly a product of positive and negative matter. Based on a basic axiom and the two foundational principles of the negative matter, we research its predictions and possible theoretical tests, in particular, the season effect. The negative matter should be a necessary development of Dirac theory. Finally, we propose the three basic laws of the negative matter. The existence of four matters on positive, opposite, and negative, negative-opposite particles will form the most perfect symmetrical world. Key words: dark matter, negative matter, dark energy, phantom, repulsive force, test, Dirac sea, inflation cosmos, Higgs mechanism. 1. Introduction The speed of an object surrounded a galaxy is measured, which can estimate mass of the galaxy.
