Is Magnetic Moment Variant or Invariant in a Plasma?

Authors: Leonard Freeman
Comments: 6 Pages.

For many years one of the basic tenets of plasma physics has been the invariance, or constancy, of the magnetic moment of a charged particle in a magnetic field that varies slowly in time or space. However it is proposed here that this is invalid. It is shown that there are contradictions within the conventional theory, and that this is due to a missing term in the derivation

Quasi-Periodic Oscillations, Mass and Jets of Black Holes: XTE J1550-564 and Sgr A*

Authors: Jacob Biemond
Comments: 32 pages, including 5 figures and 5 tables.

In this paper the recently proposed three tori model for the explanation of three high frequency quasi-periodic oscillations (QPOs) has been applied to black holes. The circular tori are: an outer torus with charge Qo, a torus with mass mm in the middle and an inner torus with charge Qi, whereas the star bears a charge Qs. Especially, the gravitational interaction between the torus with mass mm and the masses of the other two tori has been taken into account in this work. For the explanation of four low frequency QPOs a special interpretation of the gravitomagnetic theory has again been applied. Predictions of the new model are compatible with deduced high and low frequency QPOs of the stellar black hole XTE J1550-564 and the supermassive black hole Sgr A*. Moreover, the Lense-Thirring precession frequency for black holes is discussed. Furthermore, it is shown, that a massive torus around Sgr A* may lead to a higher and anisotropic observed mass for the black hole. Finally, the origin of jets is investigated by studying the radial motion of charge in the Kerr-Newman space-time. It is shown that charge may be bound on a shell slightly outside the ergosphere.

Antimatter in Voids Might Explain Dark Matter and Dark Energy

Authors: Scott S Neal
Comments: 6 pages, 3 figures

Traditional theories on cosmology require a sufficient amount of CP violation, undiscovered matter particles and missing energy to explain what is observed in our universe today. Traditional theories on antimatter assume that if antimatter atoms existed, they would distort space-time in the same way as normal matter. However, gravitational forces between antimatter atoms have not yet been experimentally measured. This paper speculates on what might happen if antimatter distorts space-time opposite to normal matter. The repulsive force of the anti-hydrogen atoms in the voids between galaxies would cause those voids to expand and would exert additional forces pressing inward on the galaxies. Simulations of this model produce galaxy rotation curves which match what is observed today without the need for any Dark Matter. An explanation of the MOND paradigm is also provided.
