Teoría del Universo Estacionario
There are many theories that try to explain how as the universe was form.
Explain the origin of the universe as a result of an explosion.
The universe origin with the explosion of a primeval atom temperature attained was eleven billons degrees and this temperature any atom or molecule can hold together
That explosion was not as we know; because it occurred simultaneously in all parts form start of the universe and filling the space of matter(atoms).
Explain that the universe has always been the same.
Explains that the universe continues in small big-bangs, followed by the big crunch.
States that there are multiples universes with different characteristics. There may be alternative or parallel universe.

PLANETS
The planets have different movements. The most important are two: the rotational and translational.
For the rotation, rotate on itself around the axle. This determines the length of day on the planet.
For the translational, planets orbits around the Sun each orbit is the year of the planet.
Each planet takes a different time to complete. The farther, longer.
Giran almost in the same plane, except Pluto, which is more inclined orbit, eccentric and elongated.
CHARACTERISTICS OF THE STARS
They are spherical, composed primarily of hydrogen and helium. Inside develop nuclear reactions that convert the fuel (hydrogen) into heavier elements (helium) and emit outside the energy resulting from this operation.
CICLE OF LIFE OF THE STARS
While interactions occur in the nucleus, supporting the body and this hydrostatics remains iridescent appearance predicted by Niels Bohr's theory of quantized orbits. When some of these interactions (the fusion of matter) expand over time, the outer parts of the object begin to merge their atoms.
MANY GALAXIES IN UNIVERSE
Astronomers think that there are at least several billion galaxies in the universe. The exact number is not known. The estimate of how many galaxies in the universe is done by counting how many galaxies we see in a small area of sky. This number is then used to calculate how many galaxies there are in the whole sky.
WILL THERE LIFE IN THE UNIVERSE?
In a recent paper, Charles Lineweaver and Tamara Davis of the University of New South Wales in Sydney, Australia, suggest that if there are other planets like Earth is likely that at least one third of hostel life.
