Calculation of the Deflection Angle of Starlight in a Gravitational Field | Chapter 5 | Current Perspective to Physical Science Research Vol. 8

 We use Newtonian mechanics to calculate the deflection angels of starlight passing around the Sun and the planets in the solar system, as well as the deflection angels of stars visible from Earth. The calculation is based on the premise that ether (Dark matter), which is a medium for light waves (electromagnetic waves), has a mass that is affected by gravity. We calculate the angle of deflection of starlight passing at perigee around the Moon and planets in our solar system. We calculate the angle of deflection of sunlight visible from Earth at sunset(sunrise) and starlight just before it disappears in the night sky. We show that the actual observed value of starlight passing around the Sun matches the calculated deflection angle using Newtonian mechanics. This means that ether (Dark matter), which has mass, exists in any space in the universe.

Preferred Frame Effects in Propagation of Cosmic and Gamma Rays | Chapter 8 | New Frontiers in Physical Science Research Vol. 8

 In this paper, the ’relativity with a preferred frame’, designed to reconcile the relativity principle with the existence of the cosmological preferred frame, is applied to electromagnetic phenomena and particle physics used to study propagation of cosmic and gamma rays in the framework of the theory. The new finding include: the modified electromagnetic field equations; modified electromagnetic wave theory and its observational consequences (such as the birefringence of light propagating in vacuo and dispersion); new features in the spectra of cosmic and gamma rays propagating through the background radiation from distant sources to Earth (such as a dependence of the threshold values for pion photoproduction by cosmic rays and pair production by gamma-rays on the distance to the source); a new mechanism of reducing or suppression of the electromagnetic cascades development by the preferred frame effects.

Establishment of Different Electromagnetic Waves Propagation Modes of Hot Plasma Located in Rotating Electromagnetic Field | Chapter 1 | New Frontiers in Physical Science Research Vol. 1

 This chapter demonstrated that depending on whether the temperature is thought to be finite or infinite, heated plasma in a rotating electromagnetic field can propagate electromagnetic waves in different ways. For this medium, we have derived the dielectric tensor expression. And we discovered that, depending on the temperature, the impacts of temperature are expressed by an exponential factor. It is important to note that at infinite temperature, the plasma is fully transparent, isotropic, and has a refractive index of one. We discovered three elliptical hybrid polarisation modes, one of which is polarised in the plane of wave propagation while the other two have their transverse components elliptically polarised in the plane perpendicular to the direction of the vector k. This is because the temperature is not too high. We have two regular transverse waves that are linearly polarised and have the same phase velocity as the speed of light in vacuum (Vph = C) in any direction of propagation.
