. Gravity is the force that pulls things towards the center of the Earth .Gravity affects almost everything in our lives . From clocks to hydroelectric dams, from the tides of the oceans to plant life, gravity plays an important role . Gravity governs our height and shape and keeps us ...
The force equals the product of these masses and of G, a universal constant, divided by the square of the distance. The constant G is a quantity with the physical dimensions (length)3/(mass)(time)2; its numerical value depends on the physical units of length, mass, and time used. (G...

the constant multipliers forXCIEandZCIEhave been expanded slightly. The ASTM D1925 method was withdrawn in 1995, but this formula still provides useful information. This index is always calculated forC/2 degrees, regardless of which illuminant and observer are chosen. The focus of this index was...
“Detecting gravitational diffusion” we show that the latter effect causes imprecision in measurements of mass such as those undertaken in the Cavendish experiment49,50,51or in measurements of Newton’s constant “BigG"52,53,54. The precision at which a mass can be measured in a short time,...
The elevated coolant tank, which is elevated above at least a portion of the coolant loop, is coupled in fluid communication with the one or more heat exchange assemblies of the heat rejection unit(s), and facilitates return of coolant to the coolant loop at a substantially constant pressure....

Abstract In this perspective, we outline that a space borne gravitational wave detector network combining LISA and Taiji can be used to measure the Hubble constant with an uncertainty less than 0.5% in ten years, compared with the network of the ground based gravitational wave detectors which can...
Here, 𝑝ˇ≠0pˇ≠0 is a constant dimensionless parameter and 𝐶ˇ𝜇Cˇμ is the torsion pseudovector defined via the Levi-Civita tensor 𝐸𝛼𝛽𝛾𝛿Eαβγδ by 𝐶ˇ𝜇:=13!𝐶𝛼𝛽𝛾𝐸𝛼𝛽𝛾𝜇.Cˇμ:=13!CαβγEαβγμ. (39) Let us note that the...
