Short Essay On Big Bang Theory

Since the first moment we realize the life around us, we are wondering about it. Who is us? Where do we come from? And what is our future? Many questions are asked to identify ourselves. The real of the universe and how it has been made are the main question the humanity has been trying to answer it. The religions, philosophy and science give a lot of theories in cosmogony. However, the big bang theory is still the most approved theory ever. The big bang theory suggests the whole universe comes from very tiny point smaller than the atom then it explodes forming this universe in very wonderful process.

About 13 billion years ago, there was nothing at all even the time except very hot and dense point and smaller the than the atom. This

Eventually Population II and then Population I stars also begin to form from the material from previous rounds of star-making. Larger stars burn out quickly and explode in massive supernova events. Supernova is the explosion of a star and is the largest explosion that takes place in space. Billions of stars groups to form galaxies and gravitational attraction pulls galaxies towards each other to form groups, clusters and super clusters. After 8.5 - 9 billion years, our solar system is formed. Our sun is considered as the late generation star and now it is in the middle of its life. Today, after 13.7 billion years the expansion of the universe and life cycle of stars continues. To sum up, the big bang theory about the birth of the universe is the most believed theory about it. The strong observational evidence to support the Big Bang theory is the amount of helium and hydrogen in the cosmos, and radio waves left over from the explosion. These are regarded as a result to the universe birth stages suggested by the theory. Illustrating how the whole universe comes from very tiny particle then it explodes forming all of the stars, galaxies and everything in the
