Big Bang Theory
We certainly know that our universe exists, however, this knowledge alone has not satisfied mankind's quest for further understanding. Our curiosity has led us to question our place in this universe and furthermore, the place of the universe itself. Throughout time we have asked ourselves these questions: How did our universe begin? How old is our universe? How did matter come to exist? Obviously, these are not simple questions and throughout our brief history on this planet much time and effort has been spent looking for some clue. Yet, after all this energy has been expended, much of what we know is still only speculation. Yet in 1927 a man by the name of Georges Lemaitre from Belgium proposed that the universe began with a bang. “He proposed that a primeval atom exploded and that is how the universe formed itself. His proposal came after observing the red shift in distant nebulas by astronomers to a model of the universe based on relativity.” Before I was enrolled in Survey of Astronomy I wasn’t sure what to believe. But after sitting through the class I started to realize that all the pieces are starting to fit together like, why the galaxies are increasing in velocity away from us and also explaining the cosmic background radiation.
About 15 billion years ago a tremendous explosion started the expansion of the universe. This explosion is known as the Big Bang. At the point of this event all of the matter and energy of space was contained at one point. What existed prior to this event is completely unknown and is a matter of pure speculation. This occurrence was not a conventional explosion but rather an event filling all of space with all of the particles of the embryonic universe rushing away from each other. 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. Even more recently, NASA’s COBE satellite was able to detect cosmic microwaves emanating from the outer reaches of the universe. These microwaves were remarkably uniform which illustrated the beginning of the early stages of the universe. However, the satellite also discovered that as the universe began to cool and was still expanding, small fluctuations began to exist due to temperature differences.
Throughout history there has always been discussions and theories as to how the universe came to be. Where did it come from? How did it happen? Was it through God that the universe was made? These philosophies have been discussed and rejected and new theories have been created. I will discuss three theories from our studies, Kalam’s Cosmological Argument, Aquinas’s Design Argument, and Paley’s Design Argument. In this article, I will discuss the arguments and what these arguments state as their belief. A common belief from these three theories is that the universe is not infinite, meaning that the universe was created and has a beginning date. Each believe that there was a God, deity, or master creator that created the universe for a reason. They also believe that
The Big Bang theory is a theory that states that the universe originated as a single mass, which subsequently exploded. The entire universe was once all in a hot and dense ball, but about 20 million years ago, it exploded. This explosion hurled material all over the place and all mater and space was created at that point in time. The gas that was hurled out cooled and became our stellar system. A red shift is a shift towards longer wavelengths of celestial objects. An example of this is the "Doppler shift." Doppler shift is what makes a car sound lower-pitched as it moves further away. As it turns out, a special version of this everyday life effect applies to light as well. If an astronomical object is moving away from the Earth, its light will be shifted to longer (red) wavelengths. This is significant because this theory indicates the speed of recession of galaxies and the distances between galaxies.

For over a hundred years now a battle has been raging over the origin of the Universe and man. Soldiers of Science have drawn the battle lines with each side using various scientific and non - scientific theories as their weapons.
The number of theories surrounding how the universe materialized is nearly endless, but Krauss’ thesis is one of the most convincing and buttressed that has been proposed. Lawrence Krauss is one of the most well respected theoretical physicists and cosmologists in America and has done extensive research on how and why the universe is in existence. Like the title of his book, A Universe from Nothing: Why There is Something Rather than Nothing, his entire theory surrounds the fact the universe was created from nothing. In support of his argument, he explores the weight and shape of the universe, dark matter and energy, quantum mechanics, visual particles, and expansion rates. While the world may never know exactly how the universe was created, society is getting closer to figuring it out and Krauss may have been the one to figure it out.
The Big Bang Theory is one of the most important, and most discussed topics in cosmology today. As such, it encompasses several smaller components that attempt to explain what happened in the moments after creation, and how the universe we know today came from such a fiery, chaotic universe in the wake of the Big Bang. One major component of the Big Bang theory is nucleosynthesis. We know that several stellar phenomena (including stellar fusion and various types of super novae) are responsible for the formation of all heavy elements up through Plutonium, however, after the advent of the Big Bang theory, we needed a way to explain what types of matter were created to form the earliest stars.!
It all started 13.7 billion years ago in the core of a black hole which contains large amounts of gravitational pressure which can squish very fine particles. After the big bang happened the universe eventually cooled and expanded. Every day the universe expands, so trying to find the end will be impossible. Our universe is similar to filling a balloon with air until expands, while keeping all of its contents inside.

Every mother has different personalities and different beliefs. In The Big Bang Theory there are two mothers that stand out the most to certain readers/viewers and they would be Beverly Hofstadter (Leonard’s mother) and Mary Cooper (Sheldon’s mother). Both have a completely different personality, but even with differences they are similar in many ways. Beverly is not religious, and over analyzes everything, while Mary is religious, and biased. Both are caring, and great mothers in their own special ways.
For centuries humans have sat outside and looked into the night sky and wondered why or how. It’s been on the minds of simpletons, philosophers and scientists alike since the beginning of time, and yet no one really has a definite answer. However, all this discussion and debate has lead to some interesting discoveries, and those theories that have stood the test of time have included both scientific and religious perspectives. One of the most famous and widely accepted of these theories is the Big Bang theory, yet even through its acceptance, it is also somewhat misunderstood. One on these misconceptions is that it explains the universes origin, a statement that is not quite true. The Big Bang Theory is an attempt in explaining how the universe has been developed, not what initiated such a creation. (Strickland, 2008)
The argument suggesting life existing on other Earth-like planets has been present since man first looked into space and questioned his own existence and the existence of others like him. Today there are many theories on the existence of intelligent life elsewhere in the universe, but only one theory goes beyond them and into an even larger realm. The contents of this theory, known as the “multiverse” theory, suggest that humans on Earth live within one universe of many others that reside within a primordial vacuum containing many other universes (Jenkins and Perez). Each of these universes possesses potentially different natural constants and physical laws that govern them differently, thus calling forth some logical questions. First, what is the likelihood such universes even exist, and second, how can we test the constants and laws that still result in the possibility of intelligent life in other universes? Moreover, what implications does this theory have on the ideology that this universe is designed specifically for human beings?
The Universe is a collection of millions of galaxies and extends beyond human imagination. After the big bang, the universe was found to be composed of radiation and subatomic particles. Information following big bang is arguable on how galaxies formed, that is whether small particles merged to form clusters and eventually galaxies or whether the universe systematized as immense clumps of matter that later fragmented into galaxies (Nasa World book, 2013). A galaxy is a massive area of empty space full of dust, gases (mainly 75% Hydrogen and 25%Helium), atoms, about 100-200 billion stars, interstellar clouds and planets, attracted to the center by gravitational force of attraction. Based on recent research, 170 billion galaxies have been estimated to exist, with only tens of thousands been discovered (Deutsch, 2011).
The big bang theory is an attempt to explain how the world began. The big bang theory begins with what is called a “singularity.” This term is used to describe an area in space which defies all the known laws of physics. Singularities are thought to exist at the core of black holes. Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that matter is pressed together into an infinite amount of pressure. The dense hot mass of the singularity slowly expanded. This process is called inflation. As the singularity expanded the universe went from dense and hot to cool and expansive. Inflation is still continuing on today which means that the universe is continually expanding.
Since the dawn of intelligent man, humanity has speculated about the origins of the universe.
