The weak force, as its name implies, is weaker than the electromagnetic or strong nuclear force, about five factors of magnitude smaller than the strong nuclear force distances in an atom's nucleus.
The theory that combines the electromagnetic force, the weak nuclear force, and the strong nuclear force is called the Grand Unification Theory (gut).
In this case, Wonder Woman's rope represents the strong nuclear force, which despite Batman and Joker's repulsion to each other, still keeps them bonded together.
Having demonstrated that the Newtonian G must be a variable of very great values at extreme energy densities, such as in the composite neutron ([[rho].sub.p,m]G~6 x [10.sup.31]), it seems reasonable to believe that the strong nuclear force is caused by such extreme values of the Newtonian gravitational factor.
The physicists found that the attractive strong nuclear force between antiprotons, which kicks in when particles are within a few millionths of a billionth of a meter of each other, overcomes the particles' repulsion due to their like charge.
In lighter-weight elements, protons and neutrons stick together because of the attractive power of the strong nuclear force. But as more and more protons get packed into a nucleus, the strong force begins to be overwhelmed by the Coulomb force, which causes particles of the same charge to repel each other.
Dimensions beyond the common three of space and one of time might explain why the strong nuclear force is roughly [10.sup.40] times stronger than gravity.
At earlier times, in the era of grand unification when energies were even higher, the electroweak interaction was united with the strong nuclear force. So whether inflation began at the time of grand unification or slightly later, when only the electromagnetic and weak interactions were unified, could determine how inflation was linked to the energy fields associated with particular elementary particles.
Gluons carry the strong nuclear force and are constantly being exchanged by the quarks, as described by the theory known as quantum chromodynamics, or QCD.
While physicists know that the strong nuclear force keeps atomic nuclei together, they cannot calculate exactly the complex interplay of forces among neutrons and protons.
DZero eospokesperson Dmitri Denisov says that measuring the lifetime and other properties of the cascade and other heavy baryons will help physicists refine their models of the strong nuclear force.
Protons and neutrons are held in place by a force called the strong nuclear force. The new finding suggests that at small distances "the strong nuclear force is more repulsive than many nuclear physicists had expected," says Lamb.
