The gravitational constant (G) is a fundamental constant in physics that describes the strength of the gravitational force between two objects. It has a value of approximately 6.67430(15) x 10-11 Newtons (m2/kg2). Gravity and Everyday Objects The gravitational attraction between everyday objects...
The field theoretic action for gravitational interactions in d+2 dimensions is constructed in the formalism of 2T-physics. General Relativity in d dimensions emerges as a shadow of this theory with one less time and one less space dimensions. The gravitational constant turns out to be a shadow ...

The acceleration due to gravity (g) is approximately a constant for objects relatively close to the Earth's surface.This gravity constant comes from the Universal Gravitation Equation at the Earth's surface. By substituting in values for the mass and radius of the Earth, you can calculate the...
The variable G, called "big G," is the universal gravitational constant. It has the same value everywhere in the universe. Newton didn't discover the value of G (Henry Cavendish found it experimentally after Newton's death), but he found the proportionality of force to mass...
Formulas for the induced Newton's constant and Eddington's constant are derived in quantized Weyl gravity. We show that the analogue of the trace anomaly for the Weyl action is structurally similar to that for the Yang-Mills action. 关键词: classical and quantum mechanics, general physics ...
‘uncharacteristic’ properties. That means the galaxies are not behaving like they’re supposed to based on the known laws of physics, in this case, the laws governing gravity. Instead of being pulled by gravity towards us, the galaxies seem to be running away from us at a rate that’s ...

I argue that the theoretical framework naturally leads to considering a weakly scale-dependent Newton's constant, with a scaling violation parameter related to the observed scaled cosmological constant (and not, as naively expected, to the Planck length). 展开 ...
