Origin Of The Universe

Origin of the universe

The universe illustrated in three spatial dimensions and a temporal dimension.
In modern cosmology, the origin of the universe is the moment in which all the matter andenergy that currently exists in the universe as a result of an explosion appeared. This nomination is openly accepted by science today and carries between 13.7 billion years old, in an instant definido.12 ago that the universe could have originated in the 1930s, the American astronomer Edwin Hubble confirmed that the universe was expanding, phenomenon that Albert Einstein's theory of generalrelativity predicted previously.

Cosmic inflation

Cosmic inflation is a set of proposals in the context of theoretical physics to explain the ultrafast expansion of the universe in the initial momentsand the so-called problem of the horizon

inflation was first proposed by the physicist and cosmologist American Alan Guth in 19811 independently and Andrei Linde, 2 and Andreas Albrecht and PaulSteinhardt3 gave it its modern form.
Although the mechanism responsible for details of the physics of particles for inflation is unknown, the basic image provides a number of predictions that have beenconfirmed by observational evidence. Inflation is currently considered part of the standard hot Big Bang cosmological model. The elementary particle or hypothetical field that is thought to beresponsible for inflation is called the inflaton.

Big bang
Interestingly, the term Big Bang comes - to his regret-English astrophysicist Fred Hoyle, one of the opponents of this theory and, in turn,one of the main proponents of the steady state theory, who in 1949, during a speech at the BBC said, to taunt, that the described model was only a big bang (big bang). However, it must be borne in mindthat at the beginning of the universe explosion nor was great, because strictly speaking it arose from a 'Singularity' infinitely small, followed by the expansion of space itself.
