Informative Essay: The Big Bang Theory

There have been various studies, predictions, and theories related to the evolution of the universe. It is an important topic that makes everyone wonder how it all started. It took centuries to finally come to a conclusion that the big bang was the start of the universe. The big bang theory took ages to become a valid model that was accepted by scientists. This model is so far, the most accepted model that validates all the discoveries of major cosmologists and astronomers such as Tycho Brahe, Nicholas Copernicus, Albert Einstein, and many more. The big bang was essentially the beginning of our galaxy including the sun, our eight planets and moons. The start of the big bang is unimaginable. It all started off as an extremely hot element that

The theory of the universe 's origin centers on a cosmic catastrophe known as the big bang. The big bang theory proponents imply that 10 billion to 20 billion years ago, a massive blast from an ancient and unknown type of energy allowed all the universe 's known matter and energy, including space and time. The big bang theory was first suggested in the 1920 's by a Belgian priest named Georges Lemaître. He theorized that the universe began from a single primordial atom. The idea received major reinforcements by Edwin Hubble 's observations that other galaxies are moving away from our own at great speed, in all directions, as if they had all been propelled by an ancient explosive force, (National Geographic, n.d.).

     The Big Bang theory states that all the matter that is in the universe was once in a very small amount of space with infinite temperature, pressure, and density. This theory is well supported and there are many reason for it’s support. One main reason is that no one really has a clue and The Big Bang Theory seems far fetched but more reasonable than any other ideas that there are out there. Some of the important thing to know about the big bang to understand are the beginning and the few seconds immediately after the actually bang. Also what generally has happened since the then. It is important to know theories of how it will end as well, and to get a well rounded opinion, I feel it useful to have some of

In short the theory provides one explanation for the creation and continued existence of the universe. The most common theory for the ‘Hot’ Big Bang is that 13.7 billion years ago the universe began as a singularity (a single point in space–time when matter is infinitely dense) then began to expand at a rapid rate.

Those who actively believe this theory, think that the universe has a beginning. They believe the universe has not always existed. They believe that one moment there was nothing and another moment the universe existed. What is currently known as the Big Bang Theory was evolved from the standard theory. The standard theory says that the universe came into existence as “singularity” around 13.7 billion years ago (Big Bang Theory). Singularities are believed to have originated at the heart of black holes. If one can see a black hole, one is too close. Therefore will be sucked into the black hole. Due to the powerful force of the black hole’s gravitational pull. A singularity is defined as interminably small in size, immensely hot in temperature and extremely dense. Those who believe in the Big Bang Theory believe the universe “expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe” (Big Bang

If you raise a somebody wherever the Universe got its begin, "the huge Bang" is that the answer you are possibly to urge. Our Universe choked with stars, galaxies and a cosmic internet of large-scale structure, all separated by the sizeableness of empty house between them, wasn 't born that manner and did not exist that manner forever. Instead, the Universe came to be this fashion as a result of it enlarged and cooled from a hot, dense, uniform, matter-and-radiation-filled state with no galaxies, stars, or perhaps atoms gift at the beginning. Everything that exists in its current kind nowadays did not exist thirteen.8 billion years past, and every one of this was puzzled out throughout the past one hundred years. however even with all this, there square measure an entire slew of facts the majority -- even several scientists -- do not quite go it. Here square measure our prime ten facts concerning the large Bang!

When infrared radiation becomes redshifted, it appears to be microwaves, which have even longer wavelengths than infrared radiation. At around the same time Dicke and Peebles were making this prediction, in 1965, two physicists at the Bell Telephone Laboratories in New Jersey, Arno Penzias and Robert Wilson, were receiving a lot of microwave interference with their equipment (Hawking 55). They had a very sensitive microwave detector, and were receiving this interference no matter where they pointed the detector. They eventually concluded that the interference was everywhere, and from outside the atmosphere, and extremely uniform. It was the same no matter what time of day, or year. This meant the microwaves they were detecting were originating from outside of the solar system, and even the galaxy (Hawking 55). It was eventually realized that this microwave background was the same that Dicke, Peeples, and Gamow had predicted. Penzias and Wilson had found the “glow” of the Big Bang. In 1992, COBE (Cosmic Background Explorer satellite) was able to find slight variations in the microwave background. This meant that the early universe was not completely even, allowing matter to clump together and structures to form such as galaxies (Hawking 56). The amount of evidence for the Big Bang was rising, and it was starting to seem like an extremely probable theory.

Big History is an exciting new way to look at our history and understand humans’ place in the world that incorporates all of time from the Big Bang to present day. (Big History Book) Big History demonstrates studying the past and learning from the past, including the origin and structure of everything, how and why people lived as they did in the world and the changes. We study the past to understand a broader and richer meaning of our world today and our place in it. The Big Bang Theory is an attempt to understand not only human’s evolution but all of the universe’s evolution from one single point to everything around us. There are eight thresholds that integrate with Big History to clarify and mark remarkable increases of complexity of the entire universe. The topic I chose to relate to Big History would be dolphins. Dolphins are highly intelligent marine animals that range in shallow areas of tropical and temperate oceans throughout the world. This animal appeals to me because as a young child, dolphins were my favorite, friendly animal. Dolphins were what I was looking forward to when I went to amusement parks as a little girl - anxiously waiting for the aquatic shows to start.

In the year 1929, Edwin Hubble made a revolutionary discovery. He learned that the universe is expanding. He saw that the galaxies were each moving away from us. Edwin knew that for one instance of time, almost 14 billion years ago, all of the mass of the universe was contained in a single spot. There had to have been a huge explosion that pushed all the matter away. This explosion is known as the Big Bang Theory. (www.science.nasa.gov)

Three main observational results over the past century led astronomers to become certain that the universe began with the big bang. First, they found out that the universe is expanding—meaning that the separations between galaxies are becoming larger and larger. This led them to deduce that everything used to be extremely close together before some kind of explosion. Second, the big bang perfectly explains the abundance of helium and other nuclei like deuterium (an isotope of hydrogen) in the universe.

The Big Bang Theory is the most accurate explanation about how the universe first began. It explains about the universe when it started with the smallest eccentricity then expanding for the next 13.8 billion years and leading to the universe, which we know today. In this essay I will be analyzing the eight thresholds of the Big Bang Theory and comparing them to the analysis of the cat lady. Cats were first domesticated in Egypt and it could be assumed that the person who tamed the animal was the former “Cat Lady.” There have been many assumptions of the origin of the name: “Some believe the notion of the “crazy cat lady” came about because of good, old-fashioned Christianity and the fact that women who were considered witches used to be burned at the stake with their cats.”(David) The Cat Ladies usually believe they are saving the cats when they pick them up from off of the street. Characteristics of a Cat Lady are maternal, socially insecure, and usually have had a hard childhood.

What exactly is the Big Bang Theory? I know before starting this essay I knew very little of what it consisted. I figured that the Big Bang Theory had something to with the era of a new generation. One in which started after the extinction of dinosaurs to be quite honest. As I learn more about astronomy, this topic struck an interest and technically the big bang theory isn’t something that occurred but rather something that happened. It started the beginning of what we now call the universe.

The time scale of the universe is very long compared to that for human life. It was therefore not surprising that until recently, the universe was thought to be essentially static, and unchanging in time. On the other hand, it must have been obvious, that society is evolving

thousand years of intellectual struggle that began with the Greek philosophers, physical scientists had reason to believe that they were beginning to understand the universe. Their theories of matter and energy, of electricity and magnetism, of heat and sound and light were confirmed in laboratories throughout the world with increasing precision. Experimentation was the method and mathematics the language of a powerful coherent body of knowledge called classical physics.
