A BIG HISTORY OF THE UNIVERSE1
The world is constantly changing. Change is considered to be one of the major patterns of
theme, which is being followed by the history of the world as it is constantly changing, without
being fixed. The main purpose of the essay is to understand the change that took place on the
earth from the time before the emergence of life, the effect on the earth after the development of
life and finally, about the human world.
Before the formation of life on the universe, the universe was considered to be an
unlimited extension of a material which is characterized by being ultra-hot. It was persisting in a
consistent state until the formation of the big bang (Downes and Nunes 2013). It can be said that
the universe emerged from the singularity before which there was no existence of space and that
of the time. Since nothing happened before the big bang, the big bang is considered as the
standard from which the time originated. The emergence of life from that of the non-living
matter is not a result of a single process; it is a result of an evolution of enhancing complexity
that tends to incorporate the molecular self- duplication, self- assemblage, the autocatalysis and
the occurrence of the cell sheaths. A various scientist is of the idea that various forms of pre-life
chemical reactions are the reasons behind the emergence of life. It is being said that before the
emergence of life on the earth, it consisted of mainly the hydrogen, helium, lithium, which
together helped in the formation of the stars. These stars came together to form the stellar
nucleosynthesis. These stars rejected heavier materials like carbon dioxide, which together
formed the rocky spheres and other forms of surfaces. However, according to the nebular theory,
the creation and that of the development of the solar system began of about 4.6 billion years ago
with the gravitational breakdown of the small sector of a giant molecular cloud. It is being said
that the majority of the failing mass got composed in that of the middle, which helped in the
formation of the sun. On the other hand, the rest compressed into a protoplanetary floppy out of
