The Big Bang Theory Humans have long been curious about the origin of the universe. They also have been curious as to how and when the Earth was formed. It all started with the Big Bang. The life we are living as we know it would not be the way it is without it. In order to better understand The Big Bang Theory one must understand what it is, how it began, the evidence, and what happened during it.
The Big Bang Theory is the approved model that scientists use to describe the beginning and original evolution of the universe. The Big Bang created all of the matter and energy in the universe, including hydrogen and helium. A few of the light atoms were forged into the cores of stars, over billions of years, or through violent explosions of supernovae

The first known stage of the universe was the Planck Epoch. When this happened, all matter was brought down to a single point of infinite density and extreme heat. During this time, it is believed that the quantum effects of gravity dominated physical interactions and that nothing had the equal strength to gravity, not even any physical …show more content…
This stage lasted from about 10 to 32 seconds in Planck time, while there is not a time as to when it stopped. Scientific models say that the universe, at this point, was filled homogeneously with a high-energy density, and that the very high temperatures and pressure started the rise to rapid expansion and cooling. Then the universe kept decreasing in density and temperature, the energy of each particle began to decrease and transitions of the phases continued until the fundamental forces of physics and elementary particles changed into their regular form. Since particle energies would have dropped to values that can be obtained by particle physics experiments, this period is subject to less speculation (Wall). According to NASA, after inflation the growth of the universe continued, but at a slower rate. As space expanded, the universe cooled and matter formed. One second after the Big Bang, the universe was filled with neutrons, protons, electrons, anti-electrons, photons, and neutrons (Williams). As we see, the Big Bang theory is the best explanation that researchers have found. Many types of evidence have been found which helps to prove the theory over and over such as, remnant radiation, Hubble’s relationship, and redshift. With the improvement of technology, further evidence has been revealed which helps prove the
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.
In many theories that come into the light in the scientific field, there are always gaps, there are always issues within each that have no explanation to them. For example, the big bang theory, this is a theory that attempts to explain how the universe was created. This theory states that the universe began as a very small, dense, and hot ball (Imagine the universe all put into a ball the size of a pen tip) with no stars or atoms. This ball then expanded incredibly quickly. The universe was then formed as the way it is now. Personally, I feel as if this theory has a major hole that prevents me from believing it is possible. This hole is, “What exactly put this ball into motion in the first place?”
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.
Matter, as we conceive it today, did not exist after the Big Bang, because the temperature was too high for that. While trying to join protons and electrons, light continually crossed apart. Only when the universe had cooled to 3,000 K, the atoms are held together and the light was beginning to happen.
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.
Cosmology is the answer when it comes down towards how the universe was created. Cosmology comes from the Greek words: kosmos-meaning world and logia- meaning study of.Cosmology is the science of the origin and the development of the universe. Mainly, everyone knows how the world
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.

Are any scientific theories true? If so why? If not why do we rely on them?
Generally, the universe began as a composition of radiation and subatomic particles, which proceeded with galaxies formation. Galaxies are made up of hydrogen, helium, 100-200 billions of stars, planets and most having a black hole at the center, which attracts everything present in galaxies by force of gravity. Galaxies can be classified as either spiral (Milky Way- galaxy which human kind has been found to exist), elliptical, lenticular and irregular, where the structure is determined by neighboring galaxies with most galaxies are moving away from each other. Classification of galaxies is being conducted by online programs such as Galaxy zoo, using pictures from telescopes and is making significant progress.
The big bang theory has evidence to support it. An example of this evidence is the cosmic microwave background. The cosmic microwave background was discovered in 1964. The cosmic microwave background is radiation left over from the beginning of the universe or the big bang. This background is important because the radiation is the type of radiation that was seen at the beg...
