The dependence of the torsion period value and the error of its estimation on the level of the acting seismic noise has been simulated and studied. To measure the Newtonian gravitational constant at the accuracy level of 10 ppm, the environmental seismic noise must be below 10-2mGal....
In particular, gravitational interactions between the particles in the vacuum fluctuations are expected on dimensional grounds to lead to a gravi- tational self-energy density of order Gµ6, where µ is some cut-off scale. Even for µ as low as 1 GeV (for no good reason) this is ...
the former is a property of the object that quantifies its inertia, the latter refers to the force of attraction created by the planet's gravitational field. Mass is a scalar quantity, and weight is a vector with a downward direction (more precisely, it points to the center of the ...

Over millions of years, gravitational interaction between Earth and the moon caused the latter to drift a few centimeters farther away each year, a slow shift that has led to their current separation of roughly a quarter of a million miles. As for Earth, the moon-forming collision was so ...
Toward understanding of the complete thermal history of the Universe: Probing the early Universe by gravitation Gravitational waves are truly transparent to matter in the Universe and carry the information of the very early epoch. We show that the energy density spec... Y Watanabe - 《Dissertations...

(assuming the ratio of the normal to the gravitational force as\(p\)to\(1\)). The altitude\(v\)that corresponds to the body’s velocity is equal to\(p \cdot Mr\)(cf. Euler1736, Prop. 25, Coroll. 5). This velocity corresponds to a distance\(2Mr\)covered by the body during ...
