Anomalies in November 2024 earth's orbit with possible explanations (original) (raw)
Intra-terrestrial verification of the gravitational shift
Canadian Journal of Physics, 2008
Einstein predicted a change in the energy of photons in the proximity of a gravitational field, the change being directly proportional to the distance from the gravitational source. In the early 1960s, Pound and Rebka (Phys. Rev. Lett. 3, 439 (1959)) set out to verify Einstein's prediction. The experiment was reprised with even higher precision by Pound and Snider (Phys. Rev. Lett. 13, 539 (1964)). Later, Vessot (Phys. Rev. Lett. 45, 2081) reprised the experiment in space at a much improved precision. In this paper, we will present an approach to the experiment that goes exactly in the opposite direction by descending towards the center of the Earth. Our new approach is less expensive, introduces stronger effects, and showcases an unprecedented second-order effect.
Recent measurements of the gravitational constant as a function of time
Physical Review D, 2015
A recent publication (J.D. Anderson et. al., EPL 110, 1002) presented a strong correlation between the measured values of the gravitational constant G and the 5.9 year oscillation of the length of day. Here, we compile published measurements of G of the last 35 years. A least squares regression to a sinusoid with period 5.9 years still yields a better fit than a straight line. However, our additions and corrections to the G data reported by Anderson et al. significantly weaken the correlation.
Improvements in absolute gravity observations
Journal of Geophysical Research, 1991
In the absolute gravity instruments developed by the Joint Institute for Laboratory Astrophysics (JILA) (Zumberge et al., 1982;, the release of the dropped object induces systematic vibrations in the floor-gravimeter system. These vibrations can cause significant errors in the observed time-distance values from which the gravitational acceleration is computed. Detailed study of the vibrations affecting the gravity observations shows them to contain random noise and site dependent systematic components, which can be modeled by decaying sinusoids in the range of 10 to 120 Hz. This paper discusses (1) a mathematical filtering method to correct the observed time-distance array by identifying and removing all non-random signals from each individual drop, (2) upgrades of the gravimeter controller, which allow the collection of the data required to implement the mathematical filtering, and (3) mechanical filtering experiments using shock dampening pads and braces to minimize the vibrations. The maximum correction to observed gravity has been 23 btGal using the mathematical filter; typical corrections are in the 2-7 btGal range. The use of the shock dampening devices alone resulted in a threefold reduction in the amplitudes and decay times of the systematic vibrations. INTRODUCIION The National Geodetic Survey (NGS) is pursuing accurate, cost effective methods to measure vertical crustal motions over regional and global scales for geodynamics studies and for monitoring global sea level [Carter et al., 1986, 1988]. One approach being tested is repetitive measurements of absolute gravity. During the past 3 years NGS has used an absolute gravity instrument developed at the Joint Institute for Laboratory Astrophysics (JILA), University of Colorado, to make approximately 85 gravity determinations at about 50 stations across the United States, Canada, and Bermuda [Peter et al., 1989]. The goal was to achieve a precision of 1-3 gGal (1 gGal (10 '8 m s '2) is equivalent to a vertical displacement of approximately 3 mm at the surface of the Earth) in an observing period of a few days. With the JILA instrument (Figure 1) absolute gravity is determined by measurements of the free-fall acceleration of a mass (an optical retroreflector) in vacuum using laser interferometry [Zurnberge, 1981; Zurnberge et al., 1982; Niebauer et al., 1986; Niebauer, 1987]. Interference fringes are counted as the retroreflector falls, and the time for each 4000th fringe generated (a distance equivalent to 2000 wavelengths of the laser light) is measured using a rubidium dock. In a single drop 170 of these time-distance observations are recorded, and the best fitting parabola (i.e., the acceleration of the dropped object) is determined using least squares methods.
The quest for the perfect gravity anomaly: Part 1 - New calculation standards
SEG Technical Program Expanded Abstracts, 2006
The North American gravity database together with databases from Canada, Mexico, and the United States are being revised to improve their coverage, versatility, and accuracy. An important part of this effort is revision of procedures and standards for calculating gravity anomalies taking into account our enhanced computational power, modern satellite-based positioning technology, improved terrain databases, and increased interest in more accurately defining different anomaly components. The most striking revision is the use of one single internationally accepted reference ellipsoid for the horizontal and vertical datums of gravity stations as well as for the computation of the theoretical gravity. The new standards hardly impact the interpretation of local anomalies, but do improve regional anomalies. Most importantly, such new standards can be consistently applied to gravity database compilations of nations, continents, and even the entire world.
Black matter and weight changes in December
gravity and black matter, 2025
Experimental evidence from earth’s orbit in November and December 2024 proves that gravity effect is caused by interactions from entitles moving in all direction in space at speed c. Gravity effects are not caused by an attraction between masses and are not caused by a space-time curvature.
Gravitational anomalies in the solar system?
L. Iorio, Gravitational anomalies in the solar system? International Journal of Modern Physics D, Vol. 24, No. 6, 1530015, 2015
Mindful of the anomalous perihelion precession of Mercury discovered by Le Verrier in the second half of the nineteenth century and its successful explanation by Einstein with his General Theory of Relativity in the early years of the twentieth century, discrepancies among observed effects in our Solar system and their theoretical predictions on the basis of the currently accepted laws of gravitation applied to known matter-energy distributions have the potential of paving the way for remarkable advances in fundamental physics. This is particularly important now more than ever, given that most of the universe seems to be made of unknown substances dubbed Dark Matter and Dark Energy. Should this not be directly the case, Solar system’s anomalies could anyhow lead to advancements in either cumulative science, as shown to us by the discovery of Neptune in the first half of the nineteenth century, and technology itself. Moreover, investigations in one of such directions can serendipitously enrich the other one as well. The current status of some alleged gravitational anomalies in the Solar system is critically reviewed. They are: (a) Possible anomalous advances of planetary perihelia. (b) Unexplained orbital residuals of a recently discovered moon of Uranus (Mab). (c) The lingering unexplained secular increase of the eccentricity of the orbit of the Moon. (d) The so-called Faint Young Sun Paradox. (e) The secular decrease of the mass parameter of the Sun. (f) The Flyby Anomaly. (g) The Pioneer Anomaly. (h) The anomalous secular increase of the astronomical unit
Low degree gravitational changes from GRACE: Validation and interpretation
Geophysical Research Letters, 2004
We examine low degree gravitational variations ΔC21, ΔS21, and ΔC20 observed by the Gravity Recovery and Climate Experiment (GRACE) satellites during the first 2 years of this gravity mission. The GRACE observations are compared with independent estimates from accurately measured Earth rotational changes and predictions from atmospheric, oceanic, and hydrological models. The 18 GRACE monthly gravity solutions, covering the period April 2002 to March 2004, show strong seasonal variability in the ΔC21, ΔS21, and ΔC20 time series, and generally agree with Earth rotation‐derived changes and geophysical model estimates, in particular for ΔS21 and ΔC20. The reason for the poorer agreement between the GRACE results and the Earth rotation‐derived estimates for ΔC21 is unclear. We demonstrate that the omission of the ocean pole tide in the GRACE data processing does have significant effects on the estimated ΔC21 and ΔS21.
The gravity field of the Earth is a resultant of three different fields, the gravitational, the centrifugal and the tidal one. Time variation of each component causes the time variation of gravity. At present the measurements by gravimeters reach such high accuracy that non-tidal variations of gravity need to be taken into consideration. The nGal sensitivity of the most modern superconducting gravime- ters may require the taking into consideration of some special new gravity effects. Two peculiar effects are discussed here. The supposed time variation of gravitational constant (suggested by the Nobel prise winner physicist Dirac in 1937) may cause the decreasing of gravity by the value of 0.1 µGal/year. The other effect is the supposed expanding Earth (suggested by the Hungar- ian geophysicist Egyed in 1970) which may cause the decreasing of gravity by the value of 0.2 µGal/year.

Foucault long pendulums, with spherical suspended mass, show Earth rotation by the constant velocity drift of their oscillation plane. Maurice Allais used a short, 84 centimeters pendulum, with a suspended bronze disc mass. He recorded its oscillation plane drift velocity, during solar eclipses, in 1954 and 1959. Both times, he noticed an anomalous drift of the oscillation plane. Several authors confirmed the effect, during next solar eclipses, with other types of pendulums. Then a group of Geophysicists, from the Science Academy of China, used an accurate digital gravimeter to measure Earth Gravity acceleration during March 09, 1997 solar eclipse. Their gravimeter recorded two drops of Earth Gravity acceleration (respectively 5.02 and 7.7 µ Gals) before and during first and last contacts of the Moon disc. However there was no acceleration drop during eclipse totality. Same phenomena were confirmed later, during next solar eclipses, with the same gravimeter. No classical causes for ...
