Cosmology

Cosmology is the study of the universe. It is a subject that most everyone has some level of interest. For example, time began in the universe at the Big Bang 13.8 billion years ago. The cosmic microwave background radiation (CMBR) was an event 377,000 years after the Big Bang when electrons coupled with atomic nuclei to produce the first neutral atoms. The CMBR was light that made the universe transparent.Cosmology has been studied by scientist for centuries trying to explain the universe. The more we seem to know the more questions need to be answered. Cosmology is an exact science, because we see universe as it is now, and we are trying to put the puzzle together to explain the story of universe.For example, there are questions about before the Big Bang. These questions are regarded by many scientist as irrelevant because they say time began at the Big Bang. This implies time did not exist before the Big Bang. This answer falls short for many people because something triggered the Big Bang. Furthermore, the energy that filled the universe was not created by the Big Bang must have come from somewhere. Before the Big Bang there was something that provided the energy. Within the blink of an eye, the Big Bang instantly inflated the universe with energy and creates a fireball that turned energy into matter.The start of the Big Bang was considered the Planck Epoch. The beginning was about 10^-50 seconds before the Big bang where the temperature increased to about 10^45 degrees kelvin. We do not know why the start of the Big Bang was pegged at a time of 10^-50 seconds before the Big Bang except to give a start time for the Planck Epoch. The Planck Epoch refers to the smallest particle of energy called the graviton which dominated this period. In the first second after the Big Bang the attractive force of gravity transformed energy into matter. The universe today is about 5% matter, 28% dark matter and 67% dark energy, but at the start of the Big Bang there was only the energy of gravity.` Today, we have a good idea of what the 5% matter in the universe is but we have little or no idea of what the rest of the 95% of the universe is.The universe works based on the physical laws of nature. Yet the universe at the quantum level is constantly changing. The universe looks steady to us, humans, but we know the universe is a violent place that is constantly evolving into something new. New stars ignite into hot plasma objects that provide energy and ten billion years latter blow up in violent explosions that throw element rich material deep into space. Galaxies constantly consume other smaller galaxies to accumulate matter to create new stars. Black Holes consume any matter or energy that gets near them including other Black Holes in a violent event that spreads gravity waves everywhere throughout the universe.As time passed the evolution of change continued everywhere, new stars ignite, new Black Holes form from the supernovae of older stars and galaxies merge to form into clusters and super clusters of matter. The entire universe is expanding as galaxies are moving apart at an accelerating rate. Today, the universe is nearly 100 billion light years across.The universe is full of matter and energy. The universe had a beginning, and it will have an ending. The process is unfolding so slowly we hardly notice the change. As we look out into deep space, we see change; all things possible are probably likely. On Earth we can see a vast variety of life has evolved. We see the solar system has developed from a violent beginning to a more stable predictable place.The size of a man exists about halfway from the scale of stars and galaxies down to the scale of the smallest quantum dimension of the Planck length which is 10^-35 meters. The Planck length is the expected size of the graviton, which is the attractive carrier particle of gravity.Our story reveals the universe in the sequence of its development over
