The Life Cycle of the Universe The Big Bang Theory is the most logical and tested explanation for the universe. Scientists believe the universe began 13.7 billion years ago, when the universe exploded outward at ten billion Kelvin. Surprisingly, scientists believe the universe was smaller than an electron before it exploded. Also, the zone in which the big bang occurred doesn’t follow the common rules of physics. This is known as a singularity, which are believed to exist only in black holes. Sadly, scientists know very little about singularities because of their complexity and difficulty to study. Luckily, The Hadron Collider, a massive machine, has the capability to recreate a miniature big bang, which would allow scientists to study
In the article The Cosmic Perspective by Neil deGrasse Tyson he examines a range of topics from human life coming from Mars to how our perspective of the universe relates to religion. In the year 2000, a new space show opened at the Hayden Planetarium called Passport to the Universe, which compared the size of people Milky Way and beyond. While a show like this might make someone feel minuscule and insignificant, Tyson says that seeing the size of the universe actually makes him feel more alive not less and gives him a sense of grandeur. I agree with his idea that looking at us as a people in comparison can actually give you a sense of grandeur. However, when I compare myself to the vastness of space, it puts events on Earth in perspective while showing how influential we can be as a people even if we are small.
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.
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.!
In the beginning there was only darkness. For many millions of years this darkness remained. There were no stars, no sun, and no earth. But one day something very special happened. The darkness created light. It was a very small amount of light but it was just enough. The light became the husband of the dark. After a long while both the light and the dark became bored. The light began to insult the dark and the light replied with equally harsh insults. "You are not as beautiful as I!" said the light. "Ha! You are much uglier than I!" said the dark.
The Big Bang is a theory that the universe was created in a very large
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.
The Earth, our home that is but a speck in a vast and ever expanding universe. Since the dawn of time humans have pondered why are we here, and who are we? During ancient times religion was the stiff spine that bound the book together, but as we have evolved so has our reliance on religion from what it once was. The earliest interpretation of our world was an archaic concept that biblical writers in Israel thought that the earth was flat and at the center of the universe. Theories like these were the mindset of the day that god was there, god was everything, later when the field of observational cosmology came to fruition with the theory of the Primordial Egg it disputed almost all that came before it. Cosmology helped us determine the “Laws
The entertainment world has given birth to several of my nemesis’. Off the top of my head, Tom Six, Jaden Smith, Miley Cyrus and the worst of all Marc Webb who had to remake a dreadful rendition of the Amazing Spiderman Franchise.
There have been numerous theories and controversies surrounding the formation of the Universe, ever since its creation. Each theory is
The Origin of Life When considering the many theories involving “How life began” You must not consider a few main theories but a few main theory groups. Because there are literally hundreds of theories on this subject which can be grouped in to three main categories and then in to various sub categories. 1) Creation science This consists of about twelve theories that are based on the book Genesis all slightly varying in their interpretation. These can be split into two main groups, New and Old earth creationists.
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.
