Gravitation, the Quantum, and Cosmological Constant
The arguments of statistical nature for the existence of constituents of active gravitational masses are presented. The present paper proposes a basis for microscopic theory of universal gravitation. Questions like the relation of cosmological constant and quantum theory, black hole radiance and the nature of inertia are addressed. This paper is the second in the series of papers published in A...
متن کاملA redetermination of the constant of gravitation
A redetermination of the constant of gravitation has boon made using the torsion balance in vacuo. The large masses were steel cylinders weighing about 66 kg, and the small masses spheres of gold, platinum, and optical glass final result obtained is 6.670 X10" cm3 g" 1 sec." . While the results obtained appeared to differ slightly with small balls of gold, platinum, or glass, it was shown by a ...
متن کاملGravitation of the Casimir Effect and the Cosmological Non-Constant
Whereas the total energy in zero-point fluctuations of the particle physics vacuum gives rise to the cosmological constant problem, differences in the vacuum give rise to real physical phenomena, such as the Casimir effect. Hence we consider the zero-point energy bound between two parallel conducting plates — proxy for a solid slice of cosmological constant — as a convenient laboratory in which...
متن کاملThe Newtonian constant of gravitation-a constant too difficult to measure? An introduction.
It is generally accepted that the magnitude of the force attracting two spherical bodies of mass M1 and M2, separated by a distance r, is given by Newton’s law of gravitation F = G M1M2 r2 . The constant, G, determines the strength of Newton’s inverse square law in a particular system of physical units and is, not surprisingly, known as Newton’s constant of gravitation. It is considered to be a...
متن کاملVerified Quadrature in Determining Newton's Constant of Gravitation
This paper describes the use of interval arithmetic to bound errors in an experiment for determining Newton's constant of gravitation. Using veri ed Gaussian quadrature we were able to assess the numerical errors as well as the e ect of several tolerances in the physical experiment.
