the local reference system is determined by the average motion of remote astronomical objects, is to be considered valid, then the notion of an expanding universe implies the variability, in fact, the gradual diminishing of the value of the gravitational constant since the time the universe began...
IS Oliveira - 《European Physical Journal B》 被引量: 17发表: 2000年 The Study of Constant Pressure Ventilation with no spontaneous respiration The ventilator which is the synthetical production of the modern science and medical technology is very useful at hospital. The ventilator is a type of ...
It goes like this: the gravitational force between two objects is equal to the mass of one times the mass of the other, multiplied by a very small number called the gravitational constant, and divided by the distan...
G is the gravitational constant, a super-icky number we can ignore for this exercise. m1 and m2 are the masses of the two objects. There are two objects because gravity isn’t a one-way thing—every two objects attract each other with an equal force. In the case of you and the Earth...
Einstein utilized the transformations because they provide a method of translating the properties from one frame of reference to another when the speed of light is held constant in both. The First Postulate of Special Relativity The first postulate of the theory of special relativity is not too ...
This explains a mysterious puzzle first pointed out by Weinberg several years ago, in a formula relating the pion mass to the Hubble Constant, a puzzle which has remained unexplained ever since.doi:10.1007/1-4020-4339-2_21B.G. SIDHARTH...
The analysis shows that the gravitational energy is the residual energy of the Planck oscillators constituting the Universe at large on the one hand, and elementary particles on the other. This explains a mysterious puzzle first pointed out by Weinberg several years ago, in a formula relating the...
If modified only a tiny bit one way or another, physical parameters such as the speed of light; the mass of the electron, proton, and neutron; the gravitational constant; and so on would eliminate all life—possibly all matter itself—and even the universe as a whole would not last long...
The equation is V = Hd, where H is the Hubble constant, or constant of proportionality. The most current estimate of H is 70 kilometers per second per megaparsec. Hubble's Law is a major piece of evidence that the universe is expanding — his work formed the basis of the big bang ...
where the universal **gravitation constant G** = 6.67 × 10-11N m2/kg2. Gravity Explained The magnitude g of the gravitational field of any "massive" object (that is, a galaxy, star, planet, moon, etc.) is expressed mathematically by the relationship: ...
