                               Early people had a different picture of universe people believe that the Earth is a flat plays as it does not have a secular shape but with the development of science and especially physically gave answers to some of the questions which were not answer for years together.

                                         Aristotle in his book talks about to basis argument

1)    He came know that the Eclipse of the moon was because of the Earth between the sun and the moon.

2)    The North Star appeared lower in the sky when seen from the southern side. 340 before crests.

                         Aristotle believe that the Earth was stagnant and the Moon, sun and plants revolved around but it was in the second century AD that the complete model was built with the name of five plants.

1)    Mercury

2)    Venus

3)    Mars

4)    Jupiter

5)    Saturn

       

                       It was in 1540 that Copernicus for the first time set that sun stagnant and all the other plant revolved around the sun but After hundred years to scientist Johannes Kipper and Goalie supported the idea of Copernicus later on science started developing and in the year of 1684. Sir Isccas Newton gave as the theory of the Law of Gravitation according of this law. It is the gravity which makes the moon to revolve around the earth gravitational force also had its effect on the movement of stars and its infinity and therefore it as impossible to have a static module of the universe in which gravity is always attractive.

                          Because of development of science people came to known about the general climate of the universe as a result the entire universe was now no longer a big question. Most of the people belive that the universe is unchanging and static but in the year 1929 Edwin Hubble found out that the galaxies are moving away from us and as a result we came to known about the big bang theory therefore people stated believing that there are physical reasons of the begging of the universe and it is not got who has created the universe.

                                   One cannot known the begging or the end of universe has  any theory is provisional and therefore hypothetical according Karl Copper any good theory is outcome of multiple observation and the goal of science it’s to provided a single theory for whole universe but it is very difficult to do so. As the observation, effects and its representation change from time to time ad to come to final conclusion is almost impossible till today there is no theory of the structure of the universe in order to calculate that orbits. Scientist today explain the universe into basic theory's

1)    The general theory of relativity

2)    Quantum mechanics.

                                   The theory of relativity describes the gravitational force the quantum mechanics talks about the smallest phenomenon of the university.

                  Physic today is searching for a new theory which can accommodate both the theories both of this theories are partial in nature.

                      

                           In order to discover the complete unified theory is very difficult start and people are still trying to search for the perfect answer on universe.
