Recommended: The big bang theory of the origin of the universe
Who or what made the universe? How did it begin? Humans have always wondered: Has the universe always existed like we see it now, or did it somehow start all of a sudden? In the past century, it was discovered that the universe was expanding and people wondered why. These are the questions the Big Bang theory tries to answer. While no one is completely sure of all the details about it, the big bang is the most widely accepted theory about the beginnings of our universe.
The big bang theory states that the universe began by expanding from an infinitesimal volume with extremely high density and temperature. It was initially smaller than the head of a pin. The theory states that space was created at the same time as the big bang and expanded carrying matter with it. Many physicists believe even time began with the big bang. The evidence supporting the big bang was so great that in 1951, the Catholic Church declared the big bang model to comply with the Bible.
One of the first discoveries made to support the big bang model was the discovery that the universe was expanding. An astronomer by the name of Vesto Slipher observed that there are more galaxies receding from the earth than are approaching it. Physicists know that a galaxy is approaching or receding by observing at the spectrum of its light. If its spectrum is toward the shorter wavelength, called Blueshift, then the galaxy is approaching and if its spectrum is toward the longer wavelength, called redshift, then the galaxy is receding. The amount of the shift depends on the speed the object is approaching or receding. Slipher observed more galaxies whose spectrums were redshifted than those whose spectrums were blueshifted.
Further support emerged in the late 1920s, when Ed...

... big bang gives a clear picture of how the universe began. By tracing back the expanding universe, scientists can picture a hot, violent beginning to the universe. Furthermore high temperatures from the start give an explanation to the high amount of helium and even the existence of deuterium. Moreover, scientists were able to detect the faint radiation from the big bang. The theory that the universe began with a big bang is essentially conclusive and may prove to be one of the greatest astronomical discoveries of mankind.

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.
Only after Vesto Slipher, Hubble and others discovered in the second decade of this century that the universe was expanding, it could give a satisfactory explanation for the paradox.
Cosmology is a field of astronomy that focuses on the framework, and emergence of the universe. Over the years, many cosmologists have contributed to the subject, using many forms of technology, to make a multitude of discoveries. Improvements in technology are responsible for superlative discoveries, chiefly about the Big Bang, the origin of our universe. The works of various cosmologists, such as Galileo Galilei, Edwin Hubble, Robert Dicke, Arno Penzias, Robert Wilson, and Vera Rubin have changed the way humanity views the universe, through their use of technology, and through their brilliance.

In support of his thesis that the universe spawned from nothing, Krauss points towards the big bang theory. The original theory was that everything was static, but Edwin Hubble proved this invalid, that the universe was actually expanding. Using advances in telescopic technology and previous knowledge of the light from stars, he correctly made this assertion. Using the very same scrutiny, Hubble determined that our Milky Way galaxy was not the only one in the universe. Krauss uses this theory to demonstrate that an expanding universe mean...
As humans mankind has always wondered where we have come from and what our purpose of life on earth is. Is there any other purpose other than to constantly reproduce amongst our species for survival? There are hundreds, possibly even thousands of stories, theories and ideas in where we came from. Some of mankind believes in different versions of religion, from Buddhism to Christianity. Others believe in that there is something out there but we as people haven’t found it yet, known as Agnosticism. Others are Atheist in that they don’t believe that there is a God. Some individuals believe we became what we are today from a big random cosmic explosion in space, known as the Big Bang Theory. Then there are others who believe that over a certain time period mankind has evolved from creatures for billions of year.
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.!
The Big Bang is a theory that the universe was created in a very large
Creation and Science We have all heard about the evolution vs. creation debate. Two sides opposing each other in fits of heated passion. One group believes that humans developed from monkeys, and the other group is a bunch of religious fanatics. Does this sound somewhat familiar?

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)
Many people every day speculate at how the universe was created and how all of space and matter began. Many people support a theory called The Big Bang Theory this theory states: fifteen billion years ago all of the matter and energy of space was contained at one point an explosion known as the big bang occurred all matter and energy moved away at a very fast rate. This theory is supported by many including me.
How life arose is a question that is fundamental to both philosophy and science. Responses to it enable one, in turn, to answer such questions as, “Who am I?”, “Why am I here?”, and “How do I make sense of this world?” This secondary set of questions can be answered in a myriad of ways for a variety of reasons, but the answer to the first question has only two responses. As Douglas Futuyuma says, “Creation and evolution, between them, exhaust the possible explanations for the origin of living things” (197). Either we are the product of the chemical and physical laws of nature operating over time, or we have been formed, at least in part, by some supernatural Force or Deity. The acceptance of one of these options as a foundation will determine how one will establish a belief system to determine his place in the world. This is a matter of crucial importance, yet in most biology classes offered at U.C. Davis, we learn that life came from nonlife by strictly natural (as opposed to supernatural) processes. The possibility that perhaps the origin of life cannot be explained by a natural mechanism is ignored, and this is disturbing. For if we limit what explanations we are willing to accept for the origin of life, we could be closing our eyes to reality.
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.
