The mysterious universe

Astronomy is the science that deals with the origin, evaluation, composition, distance and motion of all bodies and scattered matter in the universe.
All along thAstronomy is the science that deals with the origin, evaluation, composition, distance and motion of all bodies and scattered matter in the universe.ere has been a mystery regarding the beginning of creation of the universe (i.e., the world, the whole system of created things: Jahan, Alam). Science theology and philosophy have had different conceptions about it. They fail to explain the universe beyond certain limits.
Perhaps in the beginning the universe was a limitless boiling ocean of thin vapor of matter. Some people believe that originally matter was uniformly distributed in the space and from this matter were congealed out (changed from fluid to solid by cold) the heavenly bodies, perhaps in the beginning God said, ‘let there be light’ and there was light. Some people think that originally the space was flooded with light, which translated itself into energy. According to this view, Energy lay motionless over a limitless space and for ages on end there was no indication of cosmos (kai’nat- the world as an orderly or systematic whole).
Later on in the course of time, the energy took the shape of incandescent vapors of matter distributed uniformly in space. Where from this original energy came? Our science and philosophy have no reply to make. As a matter of fact our conceptions are essentially contracted by our environment of definite space and definite time and we cannot go out of these to investigate what lies beyond their confines.
Formation of the universe
Presuming, therefore, that somehow or other all the substance of the presents stars and nebulae (clusters of distance stars forming misty clouds) was at first, spread out uniformly throughout the space, it is stated by Hubble that a force of attraction (called gravitation) was thrown between the particles (molecules, as they are technically called) of this unbounded ocean of the thin matter.
Henceforth every particle of matter in space could be held in equilibrium only by an exact balancing of the forces of attraction exerted between itself and its neighbors. And it became impossible for any particle distributed from its original position to regain that state.
Therefore, the vapor separated out in myriads of condensation which dotted all around the regions of space. Each of these condensations held together its particles from flying away by attractive gravitational forces exerted by its center. As a result of the gravitational un-stability, the condensations began whirling round in such a way that their motions generated forces which sustained and overcame the gravitational un-stability and the component vapors of each individual condensation began rotating about a center. That was essential for gravitational stability. The rotation in a mass of un solidified matter also caused another change in the shape of condensation. It got flattened in an orange like shape. As the rotation increased, the flattening also increased.
A further step in the building up of the universe now took place. As these condensations rotated they also underwent contraction, with corresponding increase in the speed. This rotation and contraction continued till at last the flattening process reached their height and gave raise t further split-up into smaller condensations; for example the star, nebulae etc, as we find them today. This is how Hubble has accounted for development of the universe.
