Elon Musk does try travelling to the mars by space crafts. Such a travelling has been considered to take a time about the 3 years from the earth to the mars by ultimate technologies. But we show that travelling from the earth to the mars is done just in three days by electro antigravity of the sun on the space craft. By a change in the space craft it is possible to build a complete electrical space craft and reaching about the light speed for a space craft in the solar system

Phase modulation of gravitational waves often occupies a large bandwidth and degrades the S/N. This paper explains the basics, properties and implications of PM with examples from astronomy as well as how to eliminate PM. The focus is on the search for gravitational waves.

The idea of quantization of the gravitational dipole may be applied to any matter, including photons. That makes the photon while having near-zero (negligible for gravitation) mass obligatory holding non-zero gravitational dipole h/c. Being polarized by the gravitational field those dipoles create illusion of the additional mass (dark matter). (Because the positive charges in the gravito-electromagnetism attract, not repel like in electromagnetism, dipole polarization makes the field stronger, not weaker). The dipoles may be indeed due to the presence of the undiscovered yet particles (and even from the hypothetical particles which interact only gravitationally), but evaluations shows that simple photons have concentration in the space enough to explain the accelerated rotations of galaxies.

From the mathematical aspects of the Schwarzschild's metric, we present different methods of changing variables which tend to prove that the central singularity hypothesis does not exist. The geometric interpretation of the black hole is not mathematically convincing from the Schwarzschild metric. We recall the different mathematical approaches of several authors, the examples of the Painleve metric and its complex variant, then of the Schwarzschild metric, to deduce a metric with a throat sphere which leads to a mirror spacetime. Subsequently, we deduce the possibility of a bi-metric tangent to the Schwarzschild metric's throat sphere. We will also show that a false interpretation of the variables of the Schwarzschild metric can lead to false physical deductions and in particular to the concept of singularity. We compute the general solution of Einstein's equations in the presence of a non-zero energy tensor, i.e., for a homogeneous fluid ball with energy conditions. Our method of resolution involves a reformulation of the Einstein equation and the integration of the differential system. The metrics found are asymptotic to the Schwarzschild metric outside the fluid ball. We will present assumptions for the pressure inside the fluid ball and derive the corresponding metrics. Then, by solving the continuity equation of the energy-impulse tensor, we deduce an expression for the pressure inside the star which permits the expressing of the interior and exterior metrics.

The small-sized temperature sensor chip in a form of Schottky diode with reduced consumption, increased breakdown voltage and high linear temperature coefficient was developed. The temperature sensor chip is located in the single case of pressure sensor module. The research presents development adventures over previously used analogs of temperature sensor for external circuit of pressure sensor. Additionally, the assembly for pressure sensor chip for 25, 60 and 160 kPa ranges uses stops for both sides. It helps to increase the moment of burst pressure from 3 to 5 times relativity assembly without stops.

The main intention of this paper is to start an open discussion about a new model with the potential to find a better understanding of several observations within astronomy. As a first step a model of an entraining force is introduced based on the observation that the distances between earth and moon respectively earth and sun are slightly increasing over the year. Based on further explanation on how to calculate the entraining force and its corresponding counter-torque similar to law of induction but for moving matter. Further on an outlook is given about how this force may contribute to a better understanding about how accretion disks or planetary ring systems are forming or how it may drive the differential rotation on the surface ofgas giants but also within galaxies related to their rotary curve. In a second step the consequences of the concept are described related to the current interpretation of red-shift. If the model of the entraining force will be further verified the concept of the expanding universe might have to be revised.
