• Creationism Vs Evolution Billion Years

    Where we come from is a question as old as mankind itself. There are countless numbers of religions, each with their own twist on the origins of earth and mankind, but one of the most highly visible debates would be creationism vs. evolution. Depending on where your beliefs lie, the Earth has been around somewhere in the neighborhood of 6, 000 years to 4. 5 billion years. One would tend to believe that this vast difference in time would make it impossible to have 2 "theories" that are so widely ...

    Informative Essay 4-22-00 Freshman English 1 Big bang theory It is always a mystery about how the universe began, whether if and when it will end. Astronomers construct hypotheses called cosmological models that try to find the answer. There are two such models: the Big Bang theory and the Steady State model. Because of many observational evidences, the Big Bang theory best explains the creation of the universe. The Big Bang model postulates that about 15 to 20 billion years ago, the universe vi...

    On a clear night, only a few hundred stars can be seen without the use of any astronomical instruments. The Milky Way Galaxy consists of at least 200 billion stars. Stars are huge balls of hot gases. The sun is a star, but it is not the largest star; it is only the nearest star. A star has three recognizable stages: its birth; the years in which it exists; and its death. Its formation and its life expectancy have captured the curiosity of astronomers for centuries. Astronomers from the past hav...
  • Big Bang Theory Universe Era Space
    2,697 words
    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...

    I was at home minding my own business when all of a sudden and my bag got sucked back in time. I don't know or I can't explain really what occurred, but I found my self at the beginning of time itself. So I decided to make down my own thoughts and what I saw. Here is my journal entry. Date: No sure when (around 4. 5 billion years ago) Time: Don't ask. There were volcanoes everywhere, there was lava pouring out from the earth in large quantities. Ash was flying around my very own head landing in...

    Mass Extinction in the Precambrian As the decades pass, technological advances have enabled researchers, entrepenures and pondering minds the ability to discover more and more about every aspect of our very existence. Over the past three decades the evolutionary tree of life has been expanded at least seven times over. Major advances have been made in the area of evolution to open the eyes of many to the extensive history of the earth. For the very first time, we have tangible knowledge that lif...
  • Aquatic Life Billion Years

    Plants are critical to other life on this planet because they form the basis of all food webs. Most plants are autotrophic, creating their own food using water, carbon dioxide, and light through a process called photosynthesis. Some of the earliest fossils found have been aged at 3. 8 billion years. These fossil deposits show evidence of photosynthesis, so plants, or the plant-like ancestors of plants, have lived on this planet longer that most other groups of organisms. At one time, anything t...

    Did u know that our planet, Earth wasn't always thought of as a planet? Until the sixteenth century when Copernicus figured out that the Earth was another planet, which revolved around the sun, Greek astronomers thought the Earth was the center of the solar system. Also Earth is the only planet that its name didn't come from Greek/Roman mythology. When earth was first discovered, astronomers were only able to study it with out spacecraft. It was not until the twentieth century that we had maps o...

    LIFE CYCLE OF A STAR Stars are formed in nebulae, interstellar clouds of dust and gas (mostly hydrogen). These stellar nurseries are abundant in the arms of spiral galaxies. In these stellar nurseries, dense parts of these clouds undergo gravitational collapse and compress to form a rotating gas globule. The globule is cooled by emitting radio waves and infrared radiation. It is compressed by gravitational forces and also by shock waves of pressure from supernova or the hot gas released from nea...

    Mars: Is There Life Out There? Since 1976, when the Viking Landers took off toward the red planet, people have been wondering if there is life on Mars. There have been questions of pictures taken from Mars and skepticism about why some of the recent landings have failed. Scientists, up till now, have been doubtful about life on Mars. Everything changed on August 7, 1996, when NASA and President Clinton told the world that a very primitive life form had been found in a meteorite, from 1984. Pres...

    Vincent S. NewbillJuly 30, 2002 Eng 100 Compare and Contrast Creation vs. Evolution On November 24, 1859, a man named Charles Darwin started a controversy that has lasted to present day. His work, entitled "Origin of Species", stated the possibility that humans were not created but evolved from natural processes. Although, he was not the first to express these ideas, Darwin's published theory was neither accepted nor appreciated by the religious community. Creationism, as believed in religion, a...

    GLOBAL WARMING, A FALLACY IN THE MAKING For the last 20 years or so the subject of global warming has spawned heated debate among the world's brightest minds. Its causes and effects, if either actually exists, have been hotly debated. The most popular hypothesis is called the greenhouse effect with the agreed upon cause being green house gasses. These gasses are all naturally occurring and include water vapor, methane, oxygen, and the now infamous carbon dioxide. Greenhouse gasses exist in the ...

    Geology: A Science of Lies Geologists have put together a column that is supposed to show all the life and the different eras and times in which they existed. Scientist claim that there are several examples of the geologic column found in nature. But there is not. There are several proofs out there that show that the geologic colum does not exist. Because even Charles Darwin said in his book The Origin Of The Species Geology assuredly does not reveal any such finely-graduated organic chain To co...

    The Earth formed when the sun and its forming of planets formed when a cloud of dust and gas condensed 4. 6 billion years ago. In large areas, iron sinks to the center forming the core. The Mantle is made up from primarily of the minerals olivine and pyroxene. It takes up 80% of the planet. The oceanic crust typically differ from continental crust because Earth's surfaces cooled below 100 degrees C. Water rained out of the atmosphere. Continental Crust is very thicker then the oceanic crust. Th...
  • Did Earth's Life Originate On Mars

    On August 7, 1996, NASA announced a startling discovery - by examining a meteorite that originated on Mars, they found what they believe is evidence for a primitive form of life that may have existed on Mars 3. 6 billion years ago. More work needs to be done to confirm this preliminary result, and many scientists remain unconvinced by the present evidence. But if this preliminary result is confirmed, if the structures inside the meteorite turn out to be fossil evidence for cellular organisms, th...

    Describe the transformation of radiation into matter where followed the "Big Bang" After the Big Bang... Where the big bang is recorded to begin, the first step was radiation filling the Universe. This took between 10-12 to 10-10 seconds. At this time, the universe is lying in a dense, hot and small state. As proposed by Einstein's theory of general relativity, the expansion of the Universe can be driven by energy density in the form of matter radiation. As the radiation here was exceedingly...
