Recommended: The big bang theory of the origin of the universe
We know for certainty that our universe exists, however, being the curious beings we are we want to know how the universe came to be. There are many theories out there that try to explain it. One of the most known and taught of theories is the Big Bang Theory. This theory suggests that 13.7 billion years ago all the matter in the universe came from a singularity (zones which defy the current understanding that we have of physics; they are thought to have infinite density and extreme heat). Unexpectedly, that singularity began to expand and the universe came into being.
Big bang theorist base their theory on the following evidence. One of the evidence that supports this theory is that galaxies appear to be moving away from us at speeds that are proportional to their distance. This is known as Hubble’s Law it’s named after Edwin Hubble who is credited for the discovery of this phenomenon in 1929. Hubble observed that the universe is expanding in every direction, which makes us come to the conclusion that the universe was once compact and is now moving away from the point of origin.
Since the universe is thought to have come from a singularity which is said to have a extreme heat in it, it was believed that there should be a background heat still in existence in the universe. In 1965 two radio astronomers, Arno Penzias and Robert Wilson, discovered a 2.725 degree Kelvin (-454.765 degree Fahrenheit, -270.425 degree Celsius) Cosmic Microwave Background radiation (CMB) that is spread out across the universe. This is believed to be remnants of the extremely high-temperature from the big bang.

Due to that the universe is extremely lumpy, with massive super clusters of galaxies and great voids in space. Thus the background radiation left from the big bang must be the same. But it’s not the background radiation is smooth. In order for background radiation to work and support the big bang it must not be smooth, but should be more intense in certain direction than in other, indicating in homogeneities at the very start of the universe so that it matches the way the universe is set up right now.

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.
The agnostic’s assertion may be expressed by the sentence, “We cannot know whether there is a God or not, and we cannot know whether the universe has been in existence since eternity or not.” He believes that nothing is or can be known. If the hypothesis “Matter had a beginning” is confirmed, the assertion that “Matter had no beginning” would be refuted and the contention “We cannot know whether it had a beginning or not” will be proved wrong. Thus, demonstration of the fact that matter had a beginning is a blow not only to atheism but also to agnosticism and skepticism. Once the hypothesis of the beginning and creation of matter has been confirmed, the atheists should abandon their disbelief and the agnostics their skepticism. If you remember the words in the sura The Prophets, verse 30, “Will they not believe even then?” this statement in the verse that described the Big Bang is a sign according to which the unbelievers will stick to their own convictions, or lack of conviction. It has become clear that an agnostic is no different than a man who worships the cow and the denial of the atheist is tantamount to the adoration of fire; these people base their philosophies on absolute lack of evidence, sheer delusion, total lack of logic and scientific reasoning.
When first creating the universe that contained the characters and situations in “The Hitchiker’s Guide to the Galaxy,” Douglas Adams did not predict the impact that it would have not only on fans of the science fiction genre but society in general. This book caused everyone to want to know more about Arthur Dent and Ford Prefect. “The Hitchhiker’s Guide to the Galaxy,” is so significant because it created an impact on pop culture, combined elements of both science fiction and comedy, and created a community of dedicated fans to its universe.

CMBR has all kinds of names like: 3 Degree Kelvin Background Radiation, Cosmic Background Radiation, and Microwave Background. It has names likes these because the radiation is like a black body and its’ temperature is less than three degrees Kelvin like about 2.76K. It is cool enough for electrons and protons to recombine into hydrogen atoms. Right now the temperature is about 2.725°. “… If we could see microwaves, the entire sky would grow with a brightness…” (http://map.gsfc.nasa.gov/universe/bb_test_cmb.html). “The reason why we can still see Cosmic Microwave Background Radiation is because; the cosmic microwave background does not originate with the big bang itself. It originates roughly 380,000 years after the big bang, when the temperature dropped far enough to allow electrons and protons to form atoms. When it was released, the cosmic microwave background wasn’t microwave at all-the photons had higher energies. Since that time, they have been red shifted due to the expansion of the universe, and are presently in the microwave b...
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.!
For as long as long as history has been recorded there has been interest in how the universe came to be. The science community seems to agree that the big bang was what created the universe, but there are many conflicting arguments surrounding what existed before the big bang and what initiated it. While there are nearly infinite responses to this question, there are only two paths one can take when answering it; either something existed prior to the big bang or the entire universe came from nothing. Lawrence M. Krauss, acclaimed physicist and cosmologist, uses his understanding of science in his book, A Universe from Nothing: Why There is Something Rather than Nothing, to elucidate that it is logical for something to come from nothing. Krauss recognizes that much of the world attributes the creation to God and quotes Steven Weinberg in saying that “science does not make it impossible to believe in God, but rather makes it possible to believe in God” (183). Using the big bang theory, the discovery of both dark matter and energy, and the idea that many features of the universe do come from nothing Krauss makes a convincing argument that the universe did indeed come about with no preexistence.
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.
The Big Bang, the alpha of existence for the building blocks of stars, happened approximately fourteen billion years ago. The elements produced by the big bang consisted of hydrogen and helium with trace amounts of lithium. Hydrogen and helium are the essential structure which build stars. Within these early stars, heavier elements were slowly formed through a process known as nucleosynthesis. Nucleosythesis is the process of creating new atomic nuclei from pre-existing nucleons. As the stars expel their contents, be it going supernova, solar winds, or solar explosions, these heavier elements along with other “star stuff” are ejected into the interstellar medium where they will later be recycled into another star. This physical process of galactic recycling is how or solar system's mass came to contain 2% of these heavier elements.
The Big Bang is a theory that the universe was created in a very large
The beginning of time and the universe began with the Big Bang. This was an explosion that started the expansion of the universe. In the most basic sense, the standard model is simply the idea that every bit of the matter and energy in the universe was once compressed to an unimaginable density. In the big bang, the material exploded outward into the formation of matter that we see today. Shortly after this event everything in the universe was very dense and very hot. It was only until 500,000 years later that it cooled enough so that hydrogen and helium could form by fusion processes. Even then, it took another two billion years of cooling for enough clumps of interstellar dust and gas, called molecular clouds, to achieve stability in the universe.
I always ask myself where did the universe come from? Why everything exists instead of just nothing? Usually atheists have assumed the universe is just eternal, and that's all. However confidently this is irrational. If the universe never had a start this means that the amount of past incidents in the history of the universe is immeasurable.
Since the dawn of intelligent man, humanity has speculated about the origins of the universe.
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.
