Series Juguemos to why?
why bodies fall?
When we ask this why the response is immediate ... by the action of gravity.
But how much we know about gravity? It is good to use as an excuse to delve into this question the meaning of gravity.
There 4 (four) fundamental forces in nature.
v gravitational force: long range transmitted by the graviton (particle yet detected with current technology)
v ; Electromagnetic force: long range transmitted by photons.
v strong nuclear force: short range transmitted by gluons inside the nucleus of atoms.
v weak nuclear force: short range transmitted by inns.
(See note Easy Science No. 25)
To answer this question we limit our analysis to the gravitational force that is attached to a great mystery since it is assumed that there is a particle within matter called graviton the one that transmits it, but so far not been detected
mode that belongs to the field of theoretical physics.
The LHC at CERN (European Organization for Nuclear Research) (European Organization for Nuclear Research) near Geneva (Switzerland) started operations 30 March 2007 with an experiment that may change the scientific paradigm and revolutionize the world because through it you discover the subatomic particles that different theories supposed to exist, the concepts of physics are handled to date and change dramatically different patterns emerge which in turn boost advanced technologies.
We are living one of the most important historical moments in science.
is the Universal Science Experiment where 500 universities and 6000 involving physicists and engineers, as well as technicians and researchers worldwide.
Argentina is formally present as they are 8 (eight) the Argentines who work in this laboratory, of which 4 (four) are from the University of Buenos Aires (UBA) and the other 4 (four) of the National University of La Plata (UNLP).

The force of gravity is only attractive, so the bodies fall and all the inhabitants of this world are attached to it.
is a weak force and it is not so difficult to overcome, to raise an arm, jumping or lifting, and we're doing.
Its scope is universal, because the whole universe is affected by it.

For Einstein space-time is distorted by the presence of the masses. The space is like a huge rubber mesh sinking more, the bigger is this mass in it, gravity is motivated by this curvature so that a mass approaching another will be drawn, as if falling into a well and, all other lower body to fall closer to the body mass enhanced through the warping of space and will be attached to it if the mass is small but if it is a natural satellite for the moon or other celestial body will orbit in the same area attracted the gravitational force that affects the motion compensated by the forces that cause the translation in the universal dance of the heavenly bodies.
The mysteries are being revealed because the scientist's mind and certainly raises questions of reality seen only with limited eyes. It is necessary for the Advancement of Science that there are people who wonder why?, Who doubt the reality and to investigate to find answers.
Man is just a dot on the vast Universal but has an important purpose of being
