Cosmology Cumulative Paper In order to understand our place in the universe, we must understand the universe itself. Scientists, researchers, astronomers, cosmologists, physicists, amateur astronomers and a slew of other groups of individuals largely interested in the cosmos, help with discovering new and fascinating theories or proof of different phenomenon within the universe. Three scientific articles help readers to realize scientists are constantly deep in work to unravel the hidden truths. “Dark Matter in the Discovery Age”, “Why the Universe Had no Beginning”, and “What String Theory tells Us About the Universe” include theories vastly different from one another, but lead to the same conclusion; the universe’s creation.

Physicists choose the underground for its shielded affect, and because WIMPs have a special quality; they cannot be absorbed or reflected unlike other matters. When the WIMP hits the detector underground, the particle’s energy transfers to this detector and physicists will notice a small “thermal or light signal”(Hooper, 28). XENON-100 is an example of this experiment. This piece of equipment contains cold liquid xenon, a heavy gas present in the Earth’s atmosphere. Underground WIMP detectors are a very viable and useful equipment, and the sensitivity of these detectors have been increasing “every 15 months” (Hooper, 28). The Large Hadron Collider, LHC for short, is also used to observe potential WIMP occurence. The LHC has its home underground, built as a 17 mile ring. It is a massive circular particle accelerator, as it contains high-energy protons colliding with one another at near the speed of light. This is done to understand how the Big Bang came to be, and what was after the universe’s explosion. Because of this recreation, it is thought WIMPs are being produced in the LHC as well. Unfortunately, only a small fraction of the proton collisions result in WIMPs, and the particles are still invisible, so they cannot be directly observed. However, as physicists continue to improve the LHC, the Large Hadron Collider might just be the best equipment to observe WIMPs in the future, and to
The article ‘On the Recentness of What We Know,’ written by Verlyn Klinkenborg, is a pleasant read about the author’s fondness of astronomy and his insight regarding the science of it and knowledge gleaned from it. Klinkenborg recounts a few of his star-gazing memories and then proceeds to analyze the effects cosmological discoveries have on him personally and humanity in general. The author shares bits of theoretical history of the universe and information on the early astronomers whose hypotheses have developed that history. He goes on to reference various well known discoveries throughout the years and marvels at how drastically information in recent years has changed the stories of our universe.
The universe of the past was understood to be a simple one-galaxy model that was both unchanging and immeasurable. Theories have constantly changed and been reconstructed to better portray the progression of human understanding over time. “The cosmos began
of meltdowns. There has been many debates as to if the radiation that occurred at Three
It is important to understand the two candidate particles scientists are investigating as dark matter. The first contender that could be dark matter is a neutralino. A neutralino is a weakly interacting massive particle that has a mass of about one-thousand hydrogen atoms (Zioutas 1485). Although this particle is relatively bigger than a hydrogen atom, a particle scientists can easily observe, neutralinos are extremely hard to detect because they don’t emit an electromagnetic spectrum. In simpler terms, neutralino’s are very difficult to detect because they are weakly interacting particles that don’t produce any color or radiation. Although, neutralinos have not yet been observed directly scientists are formulating ways to observe the particle. The first way scientists are
In 1781, Carl Wilhelm Scheele discovered Tungsten, which is also known as Wolfram. The word Tungsten is used in the United States, but Wolfram is still used in some European countries. Tungsten comes from the Swedish language which means “heavy stone”. Tungsten is a very strong, shiny, gray-white metal that makes up just a tiny fraction of the earth’s crust and is always combined with other elements as compounds. Every tungsten atom has 74 positively charged protons in the nucleus which means it also has 74 negatively charged electrons revolving around the nucleus. Tungsten played a big role in the background of World War II. Portugal was the main source of this element which meant, they were put under pressure by both sides because of
For the second part of this project, I will have focused in the Cosmological Function, and my example is the sci-fi movie “The signal” (2014).
In order to detect these far-flung neutrinos, Fermilab’s neutrino beam uses an underground detector capable of measuring the neutrino composition of each shot. After being fired, the neutrinos oscillate 500 miles through the Earth’s crust. When one of the neutrinos collides with one of the atoms in the detector, a signature trail of particles and light is released which is used to identify the neutrino as an electron, muon or tau. Most neutrinos shot out of Fermilab are composed of muons, but because of this experimental method, scientists can actually infer how many are transform in transit from muon to electron.
In France and Switzerland, scientists at CERN (the European Organization for Nuclear Research) are in the process of venturing with the world's largest particle accelerator, called the Large Hadron Collider (LHC), to unlock some of the last mysteries of particle physics – the existence of substances such as dark matter, dark energy, and something called Higgs Boson. Suffice to say, the LHC is an underground tunnel, circular in nature, with a circumference of about 27km. The basic idea is to send beams of protons in opposite directions into one another, having them collide at almost the speed of light and observing what happens. Scientists are hoping to find evidence that verifies their standard model of particle physics. Rutherford's greatest contribution to the development of Science is of course his model of the atom.
From Dulce a network of tunnels spreads out to the Los Alamos Laboratory — where the first American nuclear weapons were developed and where many cutting edge technologies are still being developed — Area 51 in Nevada, Carlsbad Caverns and other places.
In this study, researchers measured the flux of muon neutrinos as a function of their energy and their incoming direction. Neutrinos with higher energies and with incoming directions closer to the North Pole are more likely to interact with matter on their way through Earth. Image credit: IceCube Collaboration
Cosmogony is the study of the origin and development of the universe as a whole and of the individual bodies that compose it. Since cosmogony deals with creation, cosmogonies of the past have been a part of religion or mythology. Modern cosmogony forms part of scientific cosmology, the study of all aspects of the large-scale physical universe, its contents and organization as well as its history. [How Stuff Works n.d.] In regards to cosmogony, the most predominantly discussed is the Big Bang. Simply, the Big Bang proposes that the universe began as a small singularity which then inflated over the next 13.8 billion years to become the cosmos known today. During this process, it expanded and cooled, going from incredibly hot to incredibly cool
McDonald and Takaaki Kajita. In the 1960s, Enrico Fermi’s beta-decay recipe was accepted as fact, and scientists were efficient at predicting the amount of neutrinos and neutrino’s energy that came from nuclear reactions. In fact, scientists were able to predict the number of neutrinos that came from the sun and could be detected by ultra-sensitive detectors on Earth. However, there was a problem: they were completely
Scientific scrutiny has unveiled in many cases how our physical universe works-how, for example, rain clouds form and how blooming flowers follow the path of the sun through the sky each day-but this does not tell us why they do so. In fact, the question “why?” is extremely difficult to answer and pausing on this question reveals to us fundamental gaps in our modern understanding of the universe. Our ancestors certainly had less information at their disposal, but through rituals, myths, and traditions they preserved the wisdom of their culture, a culture representing tens of thousands of generations of human experience, the vast majority of which escapes the current historical
There are many topics that science and religion have opposing views on and continue to debate. One of these subjects that has received a great deal of attention and has placed an enormous wedge between the two realms is the varying opinions concerning the creation of the universe. For nearly a century, scientists have explained this phenomenon with the Big Bang theory, whereas spiritual thinkers have long placed their faith in the Genesis creation account. Both submit valid arguments, however, it is ultimately up to each individual to decide which testimony to accept as truth and to consider if it is possible that both opinions could co-exist.
Man has always been interested in how the world around him works. He wondered about the structure of matter,of which his world, as well as our world, is made up. Countless scientists have been pondering that same question ever since the beginning of time. In this paper you will read about just a few of the men and women that broke the ground for the nuclear technology of today.
