The Runaway Universe

by John Cowley

3,95€ + 10% CARD

 No matter in which direction we look out from our position in space, everything is moving away from us at an ever-increasing rate. The Runaway Universe. It appears as though we are living on the surface of a balloon which is being inflated by the force of the Big Bang which first brought our universe into being. While some scientists believe that the universe will eventually run out of energy and die, others, including the author, suggest another, more exciting possibility. What if this universe is just one incarnation of a continuous series of universes that recycles through a sequence of expansions (Big Bangs) and contractions (Black Holes)? This book expands on ideas developed in Energy and Everything, the first of a three-part series by the author examining recent developments in the fields of particle physics and cosmology. Readers are invited to join the author in some interesting and challenging thought experiments designed to examine what is reality and what is illusion, all smoke and mirrors. Is the universe we live in merely a stage on which we act out our lives, telling our stories in a continuous, never-ending series of stories that join with countless other stories in a book called Life?

Cosmic Ray Intensity Variation During The Passage Of Interplanetary Disturbances

by Rajesh Kumar Mishra e Rekha Agarwal

~~15,62€~~ 14,06€ 10% OFF

 Scientific Study from the year 2024 in the subject Physics - Astronomy, , language: English, abstract: An investigation has been made to study the cosmic-ray decreases occurring during 2006 with respect to the arrival times of interplanetary shocks and magnetic clouds. We have identified three interplanetary magnetic cloud events during 5 February 2006, 13 April 2006 and 14 April 2006. The interplanetary magnetic field (B), north-south component of interplanetary magnetic field (Bz), solar wind velocity, sunspot number (R) and disturbance storm time index (Dst) associated with these events has been studied in the present work. Data (neutron monitor count rate) from Newark Neutron Monitor 9NM64 has been used. The north-south component of IMF (Bz) produce large geomagnetic disturbance on the onset of interplanetary magnetic clouds. The deviations in the interplanetary and solar wind plasma parameters are significantly correlated to the magnetic cloud events. The increase in Dst index, sunspot number (R) and Bz after the magnetic cloud event produces increase in cosmic ray intensity.

Geometry Of Coronal Mass Ejections. Cmes Geometry

by Rajesh Kumar Mishra e Rekha Agarwal

~~18,27€~~ 16,44€ 10% OFF

 Scientific Study from the year 2024 in the subject Physics - Astronomy, , language: English, abstract: The most energetic phenomena in the heliosphere are known to be coronal mass ejections (CMEs), which acquire their energy from the Sun's strained magnetic fields. Coronal Mass Ejections disrupt the flow of the solar wind and produce disturbances that strike the Earth with sometimes catastrophic results. Coronal mass ejections are often associated with solar flares and prominence eruptions but they can also occur in the absence of either of these processes. The frequency of CMEs varies with the sunspot cycle. At solar minimum we observe about one CME a week. Near solar maximum we observe an average of 2 to 3 CMEs per day. We have studied different characteristics of coronal mass ejection based on the observation form Large Angel and Spectrometric Coronagraph (LASCO) on board of the Solar and Heliospheric Observatory (SOHO) space craft during the period 1996 -2006. It is noteworthy that the rate of occurrence of Class B CMEs is more than class A CME's. The occurrence spectrum of both classes of CMEs follows the trend of the phase of solar cycle and maximum number both types CME's seems to be occurred during maximum solar activity. It is also observed that the maximum number of class A, Class B CMEs have speed range 0-500 km/sec. We have observed that maximum number of Class A, Class B CME's occurred in apparent angular width range 00-900. It is also found that the maximum number of class A and class B CME's have occurred when the position angle ranges in 50-1000 and 2500-3000 respectively.

Harmonics Of Low Amplitude Anisotropic Wave Train Events. Insights From Deep River Neutron Monitor Data (1991-94)

by Rajesh Kumar Mishra e Rekha Agarwal

~~15,99€~~ 14,39€ 10% OFF

 Scientific Study from the year 2024 in the subject Physics - Astronomy, , language: English, abstract: This study investigates the phenomenon of Low Amplitude Anisotropic Wave Train Events (LAWEs) in cosmic ray intensity using data from the ground-based Deep River neutron monitor for the period 1991-94. The analysis reveals that the amplitude of diurnal anisotropy during LAWE events consistently remains low and statistically constant compared to the quiet day annual average amplitude for the majority of events. Furthermore, the timing of the maximum diurnal anisotropy for LAWE events shifts significantly towards earlier hours, aligning with the co-rotational direction and remaining consistent with the direction of quiet day annual average anisotropy for most events. Conversely, the amplitude of semi/tri-diurnal anisotropy remains statistically high and unchanged. However, the phase shift occurs towards later hours compared to the quiet day annual average values for the majority of LAWEs. Analysis of diurnal anisotropy vectors reveals a shift towards earlier hours in 50% of events and a shift towards later hours in the remaining 50%, relative to the average vector for the entire period. Additionally, it is observed that the amplitude of these vectors significantly increases with the shift towards later hours. The study suggests that high-speed solar wind streams do not play a significant role in causing LAWE events on a short-term basis, but they may contribute to these events on a long-term basis. The occurrence of LAWE is found to be dominant when the polarity of Bx and Bz remains positive, and the polarity of By remains negative a phenomenon not reported previously. Furthermore, the amplitude of the first harmonic exhibits a good anti-correlation with solar wind velocity, while the direction of the first and third harmonics shows nearly good anti-correlation. The direction of the second harmonic shows nearly good anti-correlation with interplanetary magnetic field strength.

Cosmic Ray And Interplanetary Magnetic Field During The Passage Of Coronal Mass Ejections - Cosmic Rays And Cmes

by Rajesh Kumar Mishra e Rekha Agarwal

18,26€ + 10% CARD

 Document from the year 2023 in the subject Physics - Astronomy, , language: English, abstract: Coronal Mass Ejections are vast structures of plasma and magnetic fields that are expelled from the sun into the heliosphere. This material is detected by remote sensing and in-situ spacecraft observations. The present study deals with the influence of four types of CMEs namely Asymmetric 'Full' Halo CMEs, Partial Halo CMEs, Asymmetric and Complex 'Full' Halo CMEs and 'Full' Halo CMEs on cosmic ray neutron monitor intensity. The data of ground based neutron monitor of Moscow and CME events observed with instruments onboard and Wind spacecraft have been used in the present analysis. The method of superposed epoch (Chree) analysis has been used to the arrival times of these CMEs. It is noteworthy that the frequency of occurrence of Asymmetric 'Full' Halo CMEs is significantly high, whereas frequency of occurrence of Asymmetric and Complex 'Full' Halo CMEs is low compared to other CMEs. Significant enhancement in cosmic ray intensity is observed after 4 days of the onset of asymmetric full halo and 6 days after the onset of full halo CMEs. The fluctuations in cosmic ray intensity are more prior to the onset of both types of the CMEs. However, during Partial Halo CMEs the cosmic ray intensity peaks, 8- 9 days prior to the onset of CMEs and depressed 3 days prior to the onset of CMEs, whereas in case of asymmetric and complex full CMEs, the intensity depressed 2 days prior to the onset of CMEs and enhanced 2 days after the onset of CMEs. The deviations in cosmic ray intensity are more pronounced in case for asymmetric and complex full halo CMEs compared to other CMEs. The cosmic ray intensity shows nearly good anti-correlation with IMF strength (B) during asymmetric full halo CMEs and partial halo CMEs, whereas it shows poor correlation with B during other CMEs. The IMF, B significantly decreased five days prior to the onset of asymmetric and full halo CMEs and four days after the onset of partial halo CMEs, whereas IMF strength (B) significantly enhanced 5-6 days prior and after the onset of asymmetric and complex full halo CMEs. IMF strength (B) significantly depressed 2 days prior and 4 days after the onset of full halo CMEs. However, IMF, B significantly enhanced from its minimum to maximum values in 2 days interval prior to the onset of CMEs and in 3 days interval after the onset of CMEs.

Alternate Theory For The Big Bang And Standard Model. How Are Galaxies Created?

by Daniel Stark

15,98€ + 10% CARD

 Seminar paper from the year 2022 in the subject Physics - Astronomy, grade: 4.0, , language: English, abstract: In this paper, alternate theories for the Big Bang and Standard Model are proposed, which theorize how galaxies are created. The galaxy formation model explains how and where the fundamental particles are created. The greater universe is theorized as consisting exclusively of Dark Matter (DM) and Energy. DM has mass and is the source of the gravitational field. DM hosts kinetic and potential energy. A stable greater universe is the end result of entropy, wherein DM and energy are uniformly distributed. Fluctuations in these evenly spaced DM particles allow gravitational attraction to concentrate DM, creating galactic size DM strings. The masses of DM violate entropy by concentrating kinetic and potential energy. In these DM concentrations, collisions between large DM concentrations form a spinning DM galaxy. Inside these spinning turbulent DM galaxies, DM is theorized to undergo phase change into particle size droplets. DM droplet sphere collisions are theorized to create gamma rays by converting kinetic energy into gamma ray photons (probably via 3rd or 4th derivative of DM sphere velocity). DM spheres are predicted to capture gamma rays via Total Internal Reflection (TIR) creating a DM sphere with EM fields. Thus creating electrons, positrons, neutrons and protons. TIR is possible when the index of refraction between inside the DM sphere and outside satisfy: (n1/n2)(sin q1)>1 where n2 = 1 which is outside of the DM sphere, n1 is the DM s index of refraction and q1 is the angle from vertical to the DM s surface. These gamma rays may be generated inside of the DM sphere during the collisions or be captured because of the DM sphere s expected high index of refraction. To create a particle with EM forces, the particle must support internal standing waves, which requires the DM sphere dimension to satisfy gamma wavelength dimensions. The simplest being a half wavelength diameter sphere, which probably results in an electron or positron when capturing a gamma ray. The TIR photon provides a total positive on negative external E field because the trailing photon s E field is reversed by the lens effect during reflections inside the DM sphere, yielding an E field in the same direction as the first half of the photon's E field direction.

Shell Theorem Precludes Singularities Forming

by Daniel Stark

15,98€ + 10% CARD

 Academic Paper from the year 2022 in the subject Physics - Astronomy, grade: A, , language: English, abstract: By applying Newtonian physics, it can be shown that a singularity cannot form inside a Black Hole (BH) or anywhere in the universe. Currently, BHs are theorized inside BHs; however, these theories ignore Newton's Shell Theorem. By applying General Relativity and an incorrect maths model wherein all mass is treated as being at the centre of a mass, the gravitational field approaches infinity. Treating the mass as being at the centre of a spherical mass is only correct outside the mass body. Newton's second theorem describes the gravitational field inside a spherical mass, which is zero at its centre rather than approaching infinity. BHs with a singularity is predicted to trap photons; however, photons can escape a BH with an increase in wavelength. Radio stars may be the result wherein all visible photon wavelengths have been shifted outside the visible region, making the BH appear black. The gravitational mass does bend the photon's path, causing some oblique photons to orbit a BH.

Non-Standard Relativistic Approach For Simulating Disk Galaxies - Quasi-Particles With Reduced Relativistic Properties V ≪ V(Max) ≪ C Fit Rotation Curves Of Disk Galaxies

by Siegfried Gantert

18,27€ + 10% CARD

 Scientific Study from the year 2020 in the subject Physics - Astronomy, grade: -, , language: English, abstract: In the present work, the gravitational discrepancies observed in disk galaxies are explained using a new relativistic theory beyond the standard model of physics. It assumes the existence of bosonic quasi-particles of a scalar field, which reach different relativistic velocities v < v(max) < c depending on her effective mass. The magnitude of the limit velocity v(max) is derived from a hypothetical non-singularity condition of a quasi-particle at the velocity limit. Remarkably, it turns out that a good fit of the rotation curves is usually achieved by a relativistic velocity distribution of a galaxy-specific quasi-particle, where the maximum rotational velocity at the edge of a disk galaxy is approximately equal to the limit velocity v(max). From the relativistic velocity distribution a galaxy-specific halo with limited mass and finite size can be derived. The way dark matter can be characterized with the new approach suggests that entanglement and quantum correlation of quasi-particles plays a crucial role in the formation of a dark matter halo. To verify the model, 12 representative galaxies were selected from the SPARC data set [astroweb.cwru.edu/SPARC/] and evaluated according to the new relativistic model using the least squares regression method. A comparison of the obtained data with the empirical law of the radial acceleration relation shows high agreement. The SBM theory, which is based on a modification of special relativity theory, is applied here as a first-order approximation for bosonic quasi-particles in the asymptotic flat space of disk galaxies.

Astrobiology Of Earth - The Emergence, Evolution And Future Of Life On A Planet In Turmoil

58,29€ + 10% CARD

 The study of life in our universe has been given the name 'astrobiology'. It is a relatively new subject, but not a new discipline since it brings together several mature fields of science including astronomy, geology, biology, and climatology. An understanding of the singular conditions that allowed the only example of life that we know exists to emerge and survive on our turbulent planet is essential if we are to seek answers to two fundamental questions facing humanity: will life (and especially human life) continue on Earth, and does life exist elsewhere in the universe? Astrobiology of Earth adopts a unique approach that differs from most texts in the field which focus on the possibility of extraterrestrial life. In contrast, the central theme of this book is the fortuitous combination of numerous cosmic factors that together produced the special environment which enabled the emergence, persistence and evolution of life on our own planet, culminating in humanity. This environment has been subject to constant and chaotic change during life's 3.6 billion year history. The geologically very recent appearance of humans and their effect on the biosphere is discussed in relation to its deterioration as well as climate change. The search for extraterrestrial life is considered with a view to the suggestion that humans may escape a depleted Earth by colonizing the universe. This book contributes to our understanding of astrobiology from the perspective of life on Earth and especially human welfare and survival. Astronomical and geological phenomena are related in turn to their biological relevance and impact. This introductory text assumes little or no prior knowledge of more specialized scientific fields and is designed for undergraduate and graduate level students taking related courses in departments of biology, earth science/geology, and environmental science. It will also serve as a useful biology primer for astronomy majors.
