OF NEGATIVE MASSES, BARE MASSES & BARE CHARGES:
Consider Newton’s law of gravitation and Coulomb’s electrostatic
charge equation:
Both look similar and state that the force F between
two objects is proportional to the product of their masses m or
charges q, divided by the square of the distance r between
them. However, the minus sign in Newton's equation is accepted as suggesting
that two massive bodies attract each other while its absence in Coulomb’s law is
accepted as suggesting that two similarly charged bodies repel each other.
Secondly, the magnitude of the Coulomb's constant C is a very
large number, 8.988 × 109 Nm2/C2,
implying a strong force whereas Newton's constant G is a very
small number, 6.670 × 10-11 Nm2/kg2,
implying a weak force. Further, in Coulomb's equation, charge can be assigned
both positive and negative values, and the electrostatic force can be either
attractive or repulsive. In Newton's equation, mass is always positive, and the
force is always attractive.
One scientist (http://www.lucastechnologies.com/cosmo.html)
thought of using negative mass in a computer simulation to see how it turns
out. He took some particles - half with positive mass and half with negative
mass - threw them together in a computer simulation, and watched where they
went. The results were surprising. The like particles tended to clump together
and segregate themselves from the unlike particles with both types evolving
quickly into all sorts of structures including clusters, filaments, sheets, and
large voids. Indeed, it looked exactly like the distribution of galaxies in the
large-scale survey maps. A control simulation using only positive mass
particles produced a very nice globular cluster demonstrating that both types
of matter were necessary to form the kinds of structures seen through the
telescope. While a positive mass cluster produces a converging lens, distorting
the background galaxies into concentric arcs, negative mass would produce a
diverging lens, distorting the background galaxies into radial spokes.
