How was the origin of the universe | Earth, Solar System and Universe.

Edwin Hubble discovered that the universe is expanding. The theory of general relativity by Albert Einstein had already planned it.

It was found that galaxies move away, still today, the one from the other. If we pass the film backward, where we arrive?
Scientists try to explain the origin of the universe with different theories, supported by observations and a few coherent mathematical calculations. The most accepted are the and the Big Bang theory Inflacionaria, complemented among if.

The Big Bang theory

clip_image013
The theory of the Big Bang or big bang, supposedly, makes between 13,700 and 13.900 million of years, all the matter in the universe was concentrated in an extremely small area of space, a single point, and exploded. Matter was driven with great energy in all directions.
The shocks that inevitably from sprodujeron and a certain disorder did that matter are banded and to focus more on certain places in space, and the first stars and galaxies first formed. Since then, the universe continues in constant movement and evolution.
This theory about the origin of the universe is based on rigorous observations and is mathematically correct from a first moment after the explosion, but does not have an explanation for the time zero of the origin of the universe, called "singularity".

Inflationary theory

Alan Guth's inflationary theory attempts to explain the origin and the first moments of the universe. Based on studies of strong gravitational fields, and that there are close to a black hole.

Inflationary theory assumes that a single force was divided into the four that we now know, producing the rise to the universe.
The initial thrust lasted practically invaluable time, but the explosion was so violent that, while the attraction of gravity slows the galaxies, the universe still grows, expands.
Time Event
Big Bang Infinite density and zero volume.
10 e-43 secs. Undifferentiated forces
10 e-34 secs. Soup of elementary particles
10 e-10 secs. Protons and neutrons are formed
1 sec. 10,000,000,000 degrees. Universe size Sun
3 minutes 1,000,000,000 second. Nuclei of atoms
30 minutes 300,000,000 °. Plasma
300,000 years Atoms. Transparent universe
1,000,000 years Germs of galaxies
100 million years First galaxies
billion years Star. The rest, cools
5 billion years Formation of the milky way
10,000 million years Solar system and Earth

No one should imagine the Big Bang as the explosion of a point of matter in a vacuum, because at this point, all matter, energy, space and time were concentrated. There was no 'out' or 'before'. The space and time are also expanded with the universe.
