Big Bang Theory
Introduction
At the beginning of the 20th century, physicists generally had a strong bias toward the idea that the universe was essentially unchanging. However ,this theory does not fit with the universe phenomena which change from minute to minute, and stars and galaxies might be born and die .In this report , we will look at one of the famous theories and greatest discoveries of this century .
1. Background
1. What is the Big Bang Theory
The big bang is a theory which describes how our universe started . Many discoveries in physics and astronomy tell us that our universe in fact had a beginning .This theory became the most widely accepted theory that has come to dominate cosmology .(1:1),(3:1)
2. The beginning of the universe
According to the big bang our universe came into existence as a “singularity” about 13.7 billion years ago , but what is singularity? Singularities are zones which are thought to exist at the core of black holes. Our universe started as an infinitesimally small ,hot and dense point . Then it started to expand and cool until it reached the size and temperature of our current universe . It continues to expand and cool to this day and we are inside of it.(1:1)
2. History of Big Bang Theory
1. Edwin Hubble’s Discovery
In 1929 ,there was an incredible announcement that changed the world’s understanding of the universe . An astronomer called Edwin Hubble observed that every galaxy in the sky was moving away from us . The farther ones were moving faster than the nearby galaxies .They were heading out . What was happening ? Why is everything moving away from us ? It turns out that there is another explanation simpler and supported by many observations . The theory was that the entire universe is expanding . This explanation means that the observers in another
