These small masses also condense when orbiting the sun, forming planets and some moons. The central mass becomes an incandescent sphere, a star, our sun. Gravity gathers most of the mass into a central sphere, and around it smaller masses are rotating. The cloud began to spin faster and flatten into a disk. The shock wave produced by that explosion caused the material in our original solar nebula to begin to move. It is believed that a nearby star exploded and went supernova about 4.600 billion years ago.
This situation has happened in many places, but we are particularly interested in this one. Near the edge of this galaxy, which we now call the Milky Way, about 5 billion years ago, some of the matter was concentrated in a denser cloud. Around the middle of this period, or possibly earlier, a galaxy must have formed. We do not know what happened in the universe we are in the first 9 billion years if there are other suns, other planets, empty space, or nothing at all. Over time, as they moved further away from the center and slowed down, huge amounts of matter gathered and condensed in later galaxies. The power released at an extremely fast speed, like the speed of light, pushed this extremely dense matter in all directions. All this was enriched by transforming itself due to volcanic activity.Īccording to scientists and their studies, approximately 13.800 billion years ago there was a great explosion known as the Big Bang. Water, earth and air began to interact violently until lava from the interior of the earth emanated in abundance through the multiple cracks that existed in the earth's crust. It has not always been the same as we have it now. It is to be known that the composition of the atmosphere has evolved over the years.
Our planet was nothing more than a group of conglomerate rocks that heated up inside and outside was creating a layer of gases that formed the atmosphere.
