"Gravity is by far the weakest interaction, but it is the interaction
that has the largest range. The term long range refers technically to
the falling off of the interaction with distance r at a rate equal to
1/r2. Unlike the other interactions, gravity works universally on all
matter and energy. Because of its long range, and property of depending
only on the mass of objects and independent of their charge etc., most
interactions between objects separated by length scales larger than
that of a planet, for example, are predominantly due to gravity.
*Theory Interaction mediator Relative Magnitude Behavior Range
Chromodynamics Strong interaction gluon 1038 1 infinite
Electrodynamics Electromagnetic interaction photon 1036 1/r2 infinite
Flavordynamics Weak interaction W and Z bosons 1025 1/r5 to 1/r7 10-18
m
Geometrodynamics Gravity graviton 100 1/r2 infinite *
*Because of its long range, gravity is responsible for such large-scale
phenomena as the structure of galaxies, black holes and the expansion
of the universe, as well as more elementary astronomical phenomena like
the orbits of planets, and everyday experience: objects fall; heavy
objects act as if they were glued to the ground; people are unable to
jump very high.*Gravitation was the first kind of interaction which was
described by a mathematical theory
An area of active research today involves merging the theories of
general relativity and quantum mechanics into a more general theory of
quantum gravity. It is widely believed that in a theory of quantum
gravity, gravity would be mediated by a particle which is known as the
graviton. **Gravitons are hypothetical particles not yet observed.**
http://en.wikipedia.org/wiki/Fundamental_interaction
In physics, the graviton is a hypothetical elementary particle that
transmits the force of gravity in most quantum gravity theories. In
order to do this, one theory posits that gravitons have to be
always-attractive (gravity never pushes), work over any distance
(gravity is universal) and come in unlimited numbers (to provide high
strengths near stars).
""In this case photons are being continually created and destroyed by
all charged particles, and the interactions between these photons
produce the familiar effects of electricity and magnetism. In the same
way, the strong nuclear force and the weak nuclear force are mediated
by gluons and by W and Z bosons, respectively.

Hello,
In view of above I have few questios:-
1.Why/how gravity and graviton can't be considered as prime force and
prime particle of all forces and particles?
2. Can indicated four fundamental forces be converted, destroed or
diluted to some other fource in view of above quote?
Sorry, pls tell in less technical language.
Best Wishes
