Big Bang Theory It's inevitable that with over 6 billion people here on Earth, there will be different views upon how our universe was created. Views are mainly fueled by faith or science but the modern view of today's era is the Big Bang Theory. The theory states that the universe started at one single spot, and has been expanding ever since (Big Bang Theory, N.P.). Of course it's crazy, and highly difficult, for many of us to imagine something so large starting from one tiny spot; so indeed there are faults in the theory. Modern science however strongly supports this idea and truth be told, it's the best we have. The theory estimates that the universe is about 13.7 billion years old! This means that if this theory is correct, …show more content…
When the heat and density became to be too much, an explosion occurred resulting in a spec. From that spec, expansion occurred and from the expansion, the universe became what it is today. The radiation resulting from explosion gave birth to an unimaginably large number of particles and antiparticles. They bound together to form a sort of energy. Eventually the universe had cooled down to the point that particles stopped binding, from there the one billion left over particles settled down to become stable matter. In what can hardly be considered a fraction of a second after time zero the temperature dropped 90 percent of what it was. Another fraction later it had dropped all the way down to 30 billion K and after about 3 minutes of time the temperature was low enough for helium to be formed and stick together. In basic terms, as the temperature dropped more and more particles, electrons, protons, etc. were being created. Over the next 500,000 years the background radiation decoupled and from there it had no more significant interaction with matter. About 1 million years after time zero, stars and galaxies could begin to form and from there the inside stars turn helium and hydrogen into other elements that were heavier. The heaviness is what eventually lead to the creation of our Sun, the Earth, and all the other planets. The universe was left to expand and cool from there and has been doing
