Rain cosmic - Debris sub-atomic

In order to define the profane what is a cosmic ray, Etchegoyen uses a sports analogy: "Imagine a tennis player throwing sub-atomic particles throughout the universe.

Thousands of them bombard each square metre of the earth's surface at speeds near that of light. "Such particles, according Etchegoyen, is the most abundant around a hundred-crossing our bodies every second-but sometimes the tennis draws with more vigour and serves some nuclei heavier elements such as iron, unimaginable energies, landing on our planet at a rate of one per square kilometer every week, and others even faster and scarce rain that once a century ".

These, to penetrate the atmosphere, collide against the air molecules and break into a barrage of particles
secondary, which is called "cosmic rain", some have generated billions of them.

"The sub-atomic rubble crashed in turn against others, thus creating more branches. For when you touch land, rain is formed by billions of photons, electrons, muones and other electrically charged particles. Although the rays of energy low and moderate are well studied, the ultra-high energy remain a mystery. "
