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
singularities and the events directly after the big bang. After the big bang, the universe expanded rapidly, and began to create stars, planets, galaxies, black holes, and various types a matter. These systems grew and expanded into the universe. As of now, most of the universe is made of dark matter and dark energy, which humans cannot see. There is a possibility of finding new types of matter in space. Only 4% of the universe is made of celestial objects astronomers can see with the naked eye. Astronomers believe the universe and everything in it will die. This is also known as, the big rip. As the expansion of the universe increases, galaxies, stars, and even molecules will be ripped apart. Obviously, galaxies colliding and stars exploding cause destruction, but it is small compared to the size of the universe. The universe is 13.7 billion years old. Astronomers made this discovery when the Wilkinson Microwave Anisotropy Probe entered space. The probe collected data such as, radioactive nuclei and cosmic radiation. Astronomers also collect data on stars. Logically, the universe can’t be younger than its oldest celestial object. Therefore, astronomers can determine an age range for the universe. Works Cited
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.
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.
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?”
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
Billion years ago, there was an extra-ordinary event without which nothing would exist. It was the beginning of the universe. It was the time when a large amount of energy in an infinitely small space violently expanded and led to the creation of universe and everything else that we see around us today. It can perhaps be regarded as the greatest scientific achievement to understand the history and nature of how 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.
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.
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.
The Big Bang Theory according to National Geographic was a massive blast that had occurred 10 to 20 billions of years ago. It allowed all the universe’s known matter and energy, including space and time to evolve from an unknown type of energy, that has only been unraveled up intill the big bang. The theory believes that at the instant of that very second after the big bang had happened, the universe started to increase at an unclear rate of speed, that has not never been recorded. From what was once a small dot in the middle of a blank universe it began to expand, scientists couldn’t be sure of what went down after the big bang. All of having the thought as time slowly passed, over the billions of years the universe was still expanding, matter had cooled, and there arose a variety of atoms. Which eventually created the stars and galaxies that we can now see from our present world that we live in. The three main pieces of scientific evidence that supports the theory of the big bang that were the most important were
There have been numerous theories and controversies surrounding the formation of the Universe, ever since its creation. Each theory is
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.
There are many theories where life came from, but none of them is proven to be the right one. The obvious theory that life originated on earth is not accepted by everyone. One reason of disbelief in this theory that life originated on earth is a lack of time. It was an early belief that life originated through a slow and long process (many scientists do not share this belief though), probably too short and too long for the time life had on our planet. Life must have been formed within a period of approximately 200 million years. "If we represent the whole Christian era - two thousand years - by one inch, the time available for the emergence of life could measure as much as 1.5 miles." Another theory called "panspermia" claims that life was created somewhere else, not on earth, and traveled to our planet via meteorites or comets. Another version of "panspermia" claimed by Francis Crick and Leslie Orgel is that life was brought to earth by a spaceship sent by a more intellectual species. This theory is called "directed panspermia". The last theory might be the least likely one, since there is no actual evidence for spaceships or species from other planets. The "panspermia" theory can not be disproved and it might be possible that life came to earth via a comet. Bodies like comets contain organic molecules which are similar to the molecules of living organisms, but most scientists say that reactions creating these molecules take "place out there". We can not find an answer for this question since neither theory can totally be proven. Supporters of the "panspermia" theory say that there was not enough time for life to originate. Supporters of the theory that life originated on earth can not prove that life did not come from outer space. The Christian theory that life was created by God is abstract and will not be discussed further in this paper. Personally I believe in the theory that life was born on earth.
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.
