Development of the experiment is proceeding at Los Alamos using normal matter. The fabrication of a drift tube that will produce a region of space in which gravity is the dominant force on moving ions is of major difficulty. This involves a study of methods of minimizing the electric fields ...
"Gravity is one of the four fundamental interactions in nature, and the most important force in the evolution of stars and the universe. The research on the nature of gravity once greatly promoted the development of physics and has always been a hot subject in theoretical physics and astrophysic...

If the gravitational force on you is 670N on the earth, how strong is the gravitational force on you on the surface of a neutron star that has the same mass as our sun and a diameter of 20.0km ? Take What is the ...
Gravity, in mechanics, is the universal force of attraction acting between all bodies of matter. It is by far the weakest force known in nature and thus plays no role in determining the internal properties of everyday matter. Yet, it also controls the tr
Where F is the force of gravity, m1 and m2 are the masses of two objects and r is the distance between them. G, the gravitational constant, is a fundamental constant whose value has to be discovered through experiment. Newton's Law of Universal Gravitation says that the force of gravity ...
This second stage always develops when gravity is sufficiently low, irrespective of the gas flow rate. There are two major factors that determine the moment of bubble detachment: the buoyancy force and a force due to the momentum flowing into the bubble with the injected gas. The buoyancy ...
Thestrong coupling problemis commonly diagnosed in the Hamiltonian picture. It is usually preferred that two gravitational d.o.f propagate [15,16]. Additional d.o.f may be tolerated unless ghostly or tachyonic,Footnote1but they must kept under close theoretical and phenomenological control (e.g...
Section 6 discusses GR and its difference from the other three forces in that it is mediated by spin-2 bosons that, according to theory, should be comprised of two gluons. Section 7 discusses W. von Braun’s quest for space propulsion without fuel. B. Heim greatly influenced von Braun’s...
