 How Earth Origin And Space Deep Analysis

Various scientists and philosophers have propounded from time to time their concepts, hypothesis and theories to unravel the mystery and to solve the riddle of the problems of the origin and evolution of our solar system in general and of the earth in particular but none of these could be accepted by majority of the scientific community. Though there is no common consensus among the scientists about the origin of the our solar system but it can be safely argued that all planets of our solar system are believed to have been found by the same process. 


Origin of Earth
Origin of Earth

It means that all the concepts, hypothesis and theories propounded for the origin of the solar system are also applicable for the origin of the earth. All the views and concepts pertaining to the origin of the earth may be divided into two groups e.g.

(i) Religious concepts 
(ii) Scientific concepts

Since da religious concept do not have any logical and scientific basis, these are discarded by modern scientific community. For example, the view of Archbishop Usher (1664 in annals of the world) that the Earth was created at 9:00 A.M.(presumably Green which mean Time?) On October 26, 4004 BC is merely of fantasy.

Scientific concepts- the scientific concepts, generally based on sound principle of hard sciences, I usually divided into two School e.g. (I) 'hot origin concepts' and (ii) 'cold origin concepts'. According to the school of ' hot origin' our solar system and therefore the earth is believed to have been formed from the matter which was either initially hot or was heated up in the process of the origin of the earth. On the other hand, according to the school of ' cold origin'  our solar system together with the earth was formed of the matter which was either initially cold or always remained cold.after the formation of the earth might have been heated up due to the presence of radioactive elements or only the interior of the earth might have been heated up due to intense pressure exerted by the supe incumbent load of the upper layer. 

 On the basis of the number of heavenly bodies involved in the origin of the solar system and the scientific concepts are further divided into three groups e.g.


  • Monastic concept 
  • Dualistic concept 
  • Binary star concept
    

 Big Bang :

The big bang theory is cosmological model for the observable universe. From the earliest known periods through its subsequent large scale evolution. The model describes how the universe expanded from very high density and high temperature is state. and offers a comprehensive explanation for a broad range of phenomena, including the evidence of light element, the cosmic microwave background, large scale structure and hubble's law. If the observed condition are extrapolated backwards in in time using the known laws of physics, the prediction is that just before a period of very high density there was a singularity which is typically associated with the big bang. Current knowledge is insufficient to determine if the singularity was primordial.

Since Georges Lemaitre first noted in 1927 that an expanding universe could be traced back in time to an originating single point, scientist have built idea of cosmic expansion. the scientific community was once divided between supporters of two different theories, the big bang and the studying state theory, but a wide range of empirical evidence has strongly favored the big bang which is now universally accepted. In 1929, from analysis of Gallic redshifts, Edwin Hubble concluded that galaxies are drifting apart; this is important observational evidence for an expanding universe.in 1964 the cosmic microwave background radiation was discovered, which was crucial evidence in favour of the hot big bang model, since that theory predicted the existence of background radiation throughout the universe before it was discovered.
done on physical laws of nature can be used to calculate the characteristics of the universe in detail back in time to an initial state of extreme density and temperature. detailed measurement of the expansion rate of the universe place the big bang at around 13.8 billion year ago, which is thus considered the age of the universe. After its initial expansion, the universe old sufficiently to allow the formation of subatomic particles, and later atoms. Giant clouds of these premordial elements later coalesced gravity, eventually forming early stars and galaxies, the descendants of which are visible today. astronomers also observe the gravitational effects of dark matter surrounding galaxies. Most of the matter in the universe seems to be in the form of dark matter, and the bigbang theory and various observation indicate that it is not conventional baryonic matter. It is still not known exactly what dark matter is. More recently, measurements of the redshifts of supernovae indicate that the expansion of the universe is accelerating and observation attributed to dark energy's existence.
