The Universe, Time, Creation and everything that exists around us is unimaginably amazing as long as we understand the purpose,beauty and science of it.So how did the Universe come into existence? It all started 13 billion years ago, when there a huge explosion, that started the expansion of the Universe. This explosion was knows as The Big Bang. At the point of this event all the Energy of space was contained at one point. The Big Bang actually consisted of an explosion of space within itself unlike an explosion of a bomb were fragments are thrown outward. The galaxies were not all clumped together, but rather the Big Bang lay the foundations for the Universe. And ever since the Universe has been expanding, creating, destroying, and changing and never remaining the same for a single millisecond. It is infinite. And the expansion of the Universe is causing the galaxies to drift apart, and this phenomenon is known as the Red Shift. Immediately after the Big Bang, the universe was dense and hot, when I say hot, as a result of particles of both matter and antimatter rushing apart in all directions. As the Universe began to cool in, a fraction of a second, there existed an almost equal but asymmetrical amount of matter and antimatter. As these two materials are created together, they collide and destroy one another creating pure energy. Fortunately for us, there was an asymmetry in favor of matter. As a direct result of an excess of about one part per billion, the universe was able to mature in a way favorable for matter to persist. As the universe first began to expand, the discrepancy grew larger, the particles of matter started to dominate. As the expansion of Universe continued, and it started cooling down other particles began to form. After the Universe had cooled down to about 3000 billion degrees Kelvin, the composite particles such as protons and neutrons, commonly known as hadrons, became the common state of matter. Apart from these lighter particles called leptons also existed, but they were prohibited from reacting with hadrons to form more complex states of matter. These leptons, which include electrons, neutrinos, and photons, would soon be able to their hadron kin in a union that would define present-day common matter. After about one to three minutes since the creation of the universe, protons and neutrons began to react with each other to form deuterium, an isotope of hydrogen. Deuterium soon collected another neutron to form tritium. Rapidly following this reaction was the addition of another proton which produced a helium nucleus. Scientists believe that there was one helium nucleus for every ten protons within the first three minutes of the universe. After further cooling, these excess protons would be able to capture an electron to create common hydrogen. Consequently, the universe today is observed to contain one helium atom for every ten or eleven atoms of hydrogen.
While it is true that much of the information is speculative, as the universe ages we are becoming increasingly confident about its history. By studying the present-day universe we can learn much about its past. By finding answers to the modern questions we can trace its role in the Universe back to The Big Bang. Only through further research and discovery will it be possible for us to understand the Universe, and what our role in it is.
