One of the unsolved problems in physics is called dark matter. It should be called non-shining matter or invisible matter in order to include transparent matter. We will review the discovery of the dark matter and various explanations, some of which state that dark matter consists of baryons. In this article, we will discuss the possibility of 4He...

One of the unsolved problems in physics is how thick accretion disks produce and eject relativistic jets. ”Jet-producing disks are thick” [1]. Another unsolved problem is how quasars and active galactic nuclei persist at least millions of years, while their masses are up to milliards of solar masses. Here we suggest that these problems are connecte...

This paper investigates the relevant processes in the tornado including the dynamics of rotation and thermodynamics as well as condensation. The main novelty of this paper is the explanation of the phenomena occurring in the central downflow. The reduced pressure in the tornado’s funnel sucks air and water vapor from the cloud above the tornado. Th...

We discuss exploding stars exceeding 8 M Sun. Supernova processes start with implosion before the explosion. The processes causing implosion are relatively well understood. Not so the processes that reverse the implosion into explosion. We propose and discuss three possible processes that can reverse implosion of a star into an explosion, causing s...

The paper starts with a brief recapitulation of exponential gravitation concepts, and then continue by presenting the following items: a comparison of exponential gravitation with general relativity; gravitational radiation in exponential gravitation theory; supernova formation in the frame of exponential gravitation; a possible exponential gravita...

The Hubble law, for which the radial expansion velocity is linear in the distance r, implies a visible Universe limited to a horizon at r = c/H. No information beyond this horizon can reach us. Here we suggest a modified Hubble law for the measured radial expansion velocity that does not put a limit on the radius of the visible Universe. The modifi...

This paper presents a new line element based on the assumption of the variable rest mass in gravitational field, and explores some its implications. This line element is not a vacuum solution of Einstein's equations, yet it is sufficiently close to Schwarzschild's line element to be compatible with all of the experimental and observational measurem...

Sonochemical processes are known to occur in nature and have occurred ever since there was liquid water on Earth. We advance a hypothesis that complex carbonaceous compounds, the probable precursors of life, were produced from simple primordial molecules by sonochemical processes in breaking waves of primordial seas or oceans. Our calculations show...

We present theories of gravitation and electric potentials with exponential dependence on the reciprocal distance. In the context of this kind of electric potential we investigate the dynamics of a relativistic electron interacting with a proton.

A gedanken experiment that distinguishes locally between acceleration of rotation and linear acceleration is described and discussed.

We give a relativistic treatment to the dynamics of spherical bodies rotating at very high speed. It is found that most of the mass of a homogeneous spherical quark with Franklin rotation is due to the relativistic increase of the mass.

A new system comprising a very thin belt drive serving also as the suspension for a high speed rotor has been tested and proved feasible. Speeds of 740000 rev min-1 and acceleration fields of 4000000 g were attained, the limit being set by rotor burst strength. A simple model describing the influence of ambient pressure, drive ratio and rotor mater...

A solution for symmetric external moments is considered, taking into account a sequence of approximations and their convergence for a high-speed motor. Precessions and perturbations in the Lagrange-Poisson case are compared. It is found that the perturbation to the fast precession and slow precession involve the same phenomenon. A description of ro...
