A Solar System Test of Mach’s Principle with Gravimetric Data
نویسندگان
چکیده
We present a new test for a possible Mach-Sciama dependence of the Gravitational constant G. According to Ernst Mach (1838-1916), the gravitational interaction depends on the distribution of masses in the universe. A corresponding hypothesis of Sciama (1953) on the gravitational constant, c/G = ∑ mi/ri, can be tested since the elliptic earth orbit should then cause minute annual variations in G. The test is performed by analyzing the gravity signals of a network of superconducting gravimeters (SG) which reach a precision of 10m/s. After reducing the signal by modelling tidal, meteorologic and geophysical effects, no significant evidence for the above dependence is found.

Sizing of a Packed Bed Storage for Solar Air Heating Systems (TECHNICAL NOTE)
Packed bed units generally, represent the most suitable storage units for air heating solar systems. In these systems the storage unit receives the heat from the collector during the collection period and discharges the heat to the building at the retrieval process. A method for sizing of packedbed storage in an air heating system is represented. The design is based on the K-S curves, which hav...
متن کاملMach's Holographic Principle
Mach’s principle is the concept that inertial frames are determined by matter. We propose and implement a precise formulation of Mach’s principle in which matter and geometry are in one-to-one correspondence. Einstein’s equations are not modified and no selection principle is applied to their solutions; Mach’s principle is realized wholly within Einstein’s general theory of relativity. The key ...
متن کاملThe Lense–Thirring Effect and Mach’s Principle
We respond to a recent paper by Rindler on the “Anti–Machian” nature of the Lense–Thirring effect. We remark that his conclusion depends crucially on the particular formulation of Mach’s principle used. † Permanent address: Churchill College, Cambridge, CB3 0DS, England
متن کاملThe Pioneer anomalous acceleration: a measurement of the cosmological constant at the scale of the solar system
An anomalous constant acceleration of (8.7 ± 1.3) × 10 cm.s directed toward the Sun has been discovered by Anderson et al. in the motion of the Pioneer 10/11 and Galileo spacecrafts. In parallel, the WMAP results have definitively established the existence of a cosmological constant Λ = 1/L2U , and therefore of an invariant cosmic length-scale LU = 2.85 ± 0.25 Mpc. We show that the existence of...
متن کاملGalaxies as Rotating Buckets - a Hypothesis on the Gravitational Constant Based on Mach’s Principle
According to Mach’s principle inertia has its reason in the presence of all masses in the universe. Despite there is a lot of sympathy for this plausible idea, only a few quantitative frameworks have been proposed to test it. In this paper a tentative theory is given which is based on Mach’s critisism on Newton’s rotating bucket. Taking this criticism seriously, one is led to the hypothesis tha...
