A New Crucial Experiment for Relativity
A New Crucial Experiment for Relativity Steven Zins October 25, 2012 Abstract Dayton Miller performed an experiment in 1925{1926 that, at face value, contradicted relativity theory. The strongest argument against Miller's experiment is that subsequent Michelson-Morley experiments yielded increasing consistency with relativity, disagreeing with Miller's results. But subsequent experiments were not valid replications of Miller's. Specifically, they failed to replicate the medium in the light path and the scale of Miller's experiment. A valid replication must either be exact or be demonstrably equivalent with regard to its cru- cial sensing region. The unexplained effects seen by Miller demand exact replication. The proposed experiment is crucial for special rela- tivity but is more than a replication of Miller. This proposed Crucial Experiment should use a Michelson-Morley apparatus with a 4.25 m arm length as Miller used. The novelty of this experiment is that the light path should be in a chamber that can be operated from near zero to one atmosphere. Predictions: (1) At one atmosphere, the re- sult will agree with Miller's and contradict relativity. (2) Near zero atmospheres, the result will agree with Georg Joos' and agree with relativity. (3) Intermediate pressures will yield intermediate results. 1 Background 1.1 Origins of Ether Maxwell's formulation of electromagnetism in 1860 described the wave mo- tion of electromagnetic radiation including light. The medium that was assumed to transmit the waves was called ether. 1.2 Experiments The Michelson-Morley experiment was a test of an ether theory, specifically to determine the velocity of the Earth through an ether assumed to be fixed 1 in the solar system. -
Is the Universe Really Expanding?
Is the Universe really expanding? J.G. Hartnett School of Physics, the University of Western Australia 35 Stirling Hwy, Crawley 6009 WA Australia; [email protected] (Dated: November 22, 2011) The Hubble law, determined from the distance modulii and redshifts of galaxies, for the past 80 years, has been used as strong evidence for an expanding universe. This claim is reviewed in light of the claimed lack of necessary evidence for time dilation in quasar and gamma-ray burst luminosity variations and other lines of evidence. It is concluded that the observations could be used to describe either a static universe (where the Hubble law results from some as-yet-unknown mechanism) or an expanding universe described by the standard Λ cold dark matter model. In the latter case, size evolution of galaxies is necessary for agreement with observations. Yet the simple non-expanding Euclidean universe fits most data with the least number of assumptions. From this review it is apparent that there are still many unanswered questions in cosmology and the title question of this paper is still far from being answered. Keywords: expanding universe, static universe, time dilation I.

Einstein's Role in the Creation of Relativistic Cosmology
EINSTEIN'S ROLE IN THE CREATION OF RELATIVISTIC COSMOLOGY CHRISTOPHER SMEENK 1. Introduction Einstein's paper, \Cosmological Considerations in the General Theory of Relativ- ity" (Einstein 1917b), is rightly regarded as the first step in modern theoretical cosmology. Perhaps the most striking novelty introduced by Einstein was the very idea of a cosmological model, an exact solution to his new gravitational field equations that gives a global description of the universe in its entirety. Einstein's paper inspired a small group of theorists to study cosmological models using his new gravitational theory, and the ideas developed during these early days have been a crucial part of cosmology ever since. We will see below that understanding the physical properties of these models and their possible connections to astro- nomical observations was the central problem facing relativistic cosmology in the 20s. By the early 30s, there was widespread consensus that a class of models de- scribing the expanding universe was in at least rough agreement with astronomical observations. But this achievement was certainly not what Einstein had in mind in introducing the first cosmological model. Einstein's seminal paper was not simply a straightforward application of his new theory to an area where one would ex- pect the greatest differences from Newtonian theory. Instead, Einstein's foray into cosmology was a final attempt to guarantee that a version of \Mach's principle" holds. The Machian idea that inertia is due only to matter shaped Einstein's work on a new theory of gravity, but he soon realized that this might not hold in his “final” theory of November 1915. -

Gravity and mass It is said to have been the sight of an apple falling from a tree that, around 1665, gave Isaac Newton the idea that the force that pulls an apple to earth is the same as that which keeps the moon in its orbit around the earth. The reason the moon does not fall to earth is because of the counteracting effect of its orbital motion. If the moon were to cease its orbital motion and fall to earth, the acceleration due to gravity that it would experience at the earth’s surface would be 9.8 m/s² – the same as that experienced by an apple or any other object in free fall. Newton’s universal law of gravitation states that the gravitational force between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them. To calculate the gravitational force (F), their masses (m 1 and m 2) and the gravitational constant (G) are multiplied together, and the result is divided by the square of the distance (r) between them: F = http://ourworld.compuserve.com/homepages/dp5/gravity.htm 15.12.2006 Gravity and antigravity (1) Page 2 of 29 Gm 1m2/r². According to newtonian theory, the gravitational force between two or more bodies is therefore dependent on their masses. -
Common Misconceptions of Cosmological Horizons and the Superluminal Expansion of the Universe
CSIRO PUBLISHING www.publish.csiro.au/journals/pasa Publications of the Astronomical Society of Australia, 2004, 21, 97–109 Expanding Confusion: Common Misconceptions of Cosmological Horizons and the Superluminal Expansion of the Universe Tamara M. Davis and Charles H. Lineweaver University of New South Wales, Sydney NSW 2052, Australia (e-mail: [email protected]; [email protected]) Received 2003 June 3, accepted 2003 October 10 Abstract: We use standard general relativity to illustrate and clarify several common misconceptions about the expansion of the universe. To show the abundance of these misconceptions we cite numerous misleading, or easily misinterpreted, statements in the literature. In the context of the new standard CDM cosmology we point out confusions regarding the particle horizon, the event horizon, the ‘observable universe’ and the Hubble sphere (distance at which recession velocity = c). We show that we can observe galaxies that have, and always have had, recession velocities greater than the speed of light. We explain why this does not violate special relativity and we link these concepts to observational tests. Attempts to restrict recession velocities to less than the speed of light require a special relativistic interpretation of cosmological redshifts. We analyze apparent magnitudes of supernovae and observationally rule out the special relativistic Doppler interpretation of cosmological redshifts at a confidence level of 23σ. Keywords: cosmology: observations — cosmology: theory 1 Introduction description of the expanding universe using spacetime The general relativistic (GR) interpretation of the redshifts diagrams and we provide a mathematical summary in of distant galaxies, as the expansion of the universe, is Appendix A. -

Since 1950s, several authors have reported the so-called anomalous gravity during the total solar eclipses through various experiments. To address this issue, in the moment of the total solar eclipse of 9 March 2016 passing most regions in Indonesia, we undertook microgravity measurements using two precise gravimeters. The measurements were made at two locations: (1) Poso (central Sulawesi), a location close to the centre passage of the total eclipse and (2) Lembang (West Java), the site of Bosscha Observatory, where the partial solar eclipse occurred. -
Hubble's Diagram and Cosmic Expansion
Hubble’s diagram and cosmic expansion Robert P. Kirshner* Harvard–Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, MA 02138 Contributed by Robert P. Kirshner, October 21, 2003 Edwin Hubble’s classic article on the expanding universe appeared in PNAS in 1929 [Hubble, E. P. (1929) Proc. Natl. Acad. Sci. USA 15, 168–173]. The chief result, that a galaxy’s distance is proportional to its redshift, is so well known and so deeply embedded into the language of astronomy through the Hubble diagram, the Hubble constant, Hubble’s Law, and the Hubble time, that the article itself is rarely referenced. Even though Hubble’s distances have a large systematic error, Hubble’s velocities come chiefly from Vesto Melvin Slipher, and the interpretation in terms of the de Sitter effect is out of the mainstream of modern cosmology, this article opened the way to investigation of the expanding, evolving, and accelerating universe that engages today’s burgeoning field of cosmology. he publication of Edwin Hub- ble’s 1929 article ‘‘A relation between distance and radial T velocity among extra-galactic nebulae’’ marked a turning point in un- derstanding the universe. In this brief report, Hubble laid out the evidence for one of the great discoveries in 20th cen- tury science: the expanding universe. Hubble showed that galaxies recede from us in all directions and more dis- tant ones recede more rapidly in pro- portion to their distance. His graph of velocity against distance (Fig. 1) is the original Hubble diagram; the equation that describes the linear fit, velocity ϭ ϫ Ho distance, is Hubble’s Law; the slope of that line is the Hubble con- ͞ stant, Ho; and 1 Ho is the Hubble time. -

This work is based on the first results from a systematic search for high redshift Type Ia supernovae. Using filters in the R-band we dis- covered seven such SNe, with redshift z =0:3 0:5, before or at maximum light. Type Ia SNe are known to be a homogeneous− group of SNe, to first order, with very similar light curves, spectra and peak luminosities. In this 1Presented by G. Goldhaber, e-mail address:[email protected] 2Current address: CNRS-IN2P3, University of Paris 3Current address: Anglo-Australian Observatory 2 talk we report that the light curves we observe are all broadened (time dilated) as expected from the expanding universe hypothesis. Small vari- ations from the expected 1 + z broadening of the light curve widths can be attributed to a width-brightness correlation that has been observed for nearby SNe (z<0:1). -
A New Confirmation of the Allais Effect During the Solar Eclipse of 31 May 2003
THE PUBLISHING HOUSE PROCEEDINGS OF THE ROMANIAN ACADEMY, Series A, OF THE ROMANIAN ACADEMY Volume 5, Number 3/2004, pp. 000-000 A NEW CONFIRMATION OF THE ALLAIS EFFECT DURING THE SOLAR ECLIPSE OF 31 MAY 2003 Ieronim MIHĂILĂ, Nicolae MARCOV, Varujan PAMBUCCIAN, Ovidiu RACOVEANU University of Bucharest, Faculty of Mathematics and Informatics, Str. Academiei 14, 010014 Bucharest, Romania Corresponding author: Ieronim MIHĂILĂ, E-mail: [email protected] During the solar eclipse of 31 may 2003, the Allais effect was studied in Bucharest, using a Foucault pendulum. The effect was determined calculating the difference of the azimuth during the eclipse (Ae) and the azimuth outside the eclipse (Ar). The motion of the plane of oscillation became slower after the maximum of the eclipse, the deviation | Ae − Ar | reaching approximately 1.7° by the end of the eclipse, and afterwards it reached the maximum value of order of 2.8° − 2.9°. On the other hand, in the neighbourhood of the maximum of the eclipse the period of oscillation suffered a little growth, the relative increase being of about 2.6 × 10−6. Key words: Foucault effect, Allais effect, eclipse, gravitation. 1. PRELIMINARIES During the total solar eclipse of 11 August 1999, at the University of Bucharest, the existence of the Allais effect was confirmed [1]. This effect, which constitutes a disturbance of the Foucault effect, consists in a decrease of the angular rotation velocity of the oscillation plane of the pendulum during the solar eclipse. It was discovered by Professor Maurice Allais, in Paris, during the Sun eclipses from 1954 [2] and 1959 [3]. -
Observational Evidence Favors a Static Universe
1 Observational evidence favors a static universe David F. Crawford Sydney Institute for Astronomy, School of Physics, University of Sydney. Correspondence: 44 Market St, Naremburn, 2065, NSW, Australia email: [email protected] Abstract The common attribute of all Big Bang cosmologies is that they are based on the assumption that the universe is expanding. However exam- ination of the evidence for this expansion clearly favors a static universe. The major topics considered are: Tolman surface brightness, angular size, type 1a supernovae, gamma ray bursts, galaxy distributions, quasar dis- tributions, X-ray background radiation, cosmic microwave background ra- diation, radio source counts, quasar variability and the Butcher{Oemler effect. An analysis of the best raw data for these topics shows that they are consistent with expansion only if there is evolution that cancels the effects of expansion. An alternate cosmology, curvature cosmology, is a tired-light cosmology that predicts a well defined static and stable uni- verse and is fully described. It not only predicts accurate values for the Hubble constant and the temperature of cosmic microwave background radiation but shows good agreement with most of the topics considered. Curvature cosmology also predicts the deficiency in solar neutrino pro- duction rate and can explain the anomalous acceleration of Pioneer 10. Note: The editor of the Journal of Cosmology required this paper to be divided into three parts. Except for the abstracts, introductions and conclusions the text of the -

We analyze the views of Edwin Hubble (1889–1953) as regards the large scale structure of the universe. In 1929 he initially accepted a finite ex- panding universe in order to explain the redshifts of distant galaxies. Later on he turned to an infinite stationary universe and a new principle of nature in order to explain the same phenomena. Initially, he was impressed by the agreement of his redshift-distance relation with one of the predictions of de Sitter’s cosmological model, namely, the so-called “de Sitter effect,” the phenomenon of the scattering of material particles, leading to an expanding universe. A number of observa- tional evidences, though, made him highly skeptical with such a scenario. They were better accounted for by an infinite static universe. The evidences he found were: (i) the huge values he was getting for the “recession” velocities of the neb- ulae (1,800 km s−1 in 1929 up to 42,000 km s−1 in 1942, leading to v/c = 1/7), with the redshifts interpreted as velocity-shifts. -

An observer-based referential that is consistent with cosmological observations Théophile Caby LAMIA, Université des Antilles [email protected] Abstract We propose an alternative explanation for the redshift of cosmological objects. In this approach, the wavelength of a photon is affected by the spatial curvature in- tegrated along its trajectory from the source to the observer. We explain this effect by postulating that all measurements are performed in an observer-based represen- tation referential that has the geometrical properties of flat space, resulting in a distortion of lengths associated to distant objects. Applying these considerations in the Einstein’s static universe, we obtain a redshift/distance relationship that is consistent with observations. We are also able to explain the existence and charac- teristics of the Cosmic Microwave Background.
