Mechanics is considered in a universe containing negative mass. Demanding (i) conservation of momentum, (ii) principle of equivalence, (iii) no runaway motions, (iv) no Schwarzschild black holes, and (v) the inertial and active gravitational masses of a body shall have the same sign, we find thatall mass must be negative. Some properties of such a universe are investigated. We show that a neutral spherical body of arbitrarily small size is possible, and observers external to it can communicate… Expand

A consideration of the possibility of negative mass
SummaryThe inclusion of negative mass into Newton's laws of motion and gravitation is considered, and, as in previous investigations, no contradictions are discovered. A necessary modification to theExpand
On the existence of exotic matter in classical Newtonian mechanics.
According to Newton's law of gravitation the force between two particles depends upon their inertial, as well as their active and passive gravitational masses. For ordinary matter all three of theseExpand
Can a negative-mass cosmology explain dark matter and dark energy?
A recent study by Farnes (2018) proposed an alternative cosmological model in which both dark matter and dark energy are replaced with a single fluid of negative mass. This paper presents a criticalExpand
NEGATIVE MATTER PROPULSION
Negative matter is a hypothetical form of matter whose active-gravitational, passive-gravitational, inertial, and rest masses are opposite in sign to normal, positive matter. Negative matter is notExpand
A unifying theory of dark energy and dark matter: Negative masses and matter creation within a modified ΛCDM framework
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: gravitationallyExpand
Negative mass hypothesis in cosmology and the nature of dark energy
The observed acceleration of the universe arises a puzzling question. What is the nature of a dark energy that would cause this phenomenon? We recall the arguments against the existence of negativeExpand
Numerical Study of the Interaction Between Positive and Negative Mass Objects in General Relativity
Based on Baumgarte–Shapiro–Shibata–Nakamura formalism and moving puncture method, we demonstrate the first numerical evolutions of the interaction between positive and negative mass objects. UsingExpand
Constants and cosmology: The nature and origin of fundamental constants in astrophysics and particle physics
We ask about the nature and origin of the fundamental constants of astrophysics and particle physics, notably the speed of light c, the gravitational constant G, Planck's constant h, and theExpand
Cosmological implications of a nonseparable 5D solution of the vacuum Einstein field equations
An exact class of solutions of the 5D vacuum Einstein field equations (EFEs) is obtained. The metric coefficients are found to be nonseparable functions of time and the extra coordinate l and theExpand
Supergravity Domain Walls
Abstract We review the status of domain walls in N = 1 supergravity theories for the vacuum domain walls as well as dilatonic domain walls. We concentrate on a systematic analysis of the nature ofExpand
