Whether it was spending ÅÇrigid nights beneath the open observatory dome photographing nebulae¡¦(Parshall et al, 1998, p.PG) or forever challenging the concepts that he deemed unsubstantial, Hubble made it his lifelong ambition to ascertain as much information about the universeÃÔ vastness as he possibly could. Of all the monumental discoveries that were credited to HubbleÃÔ perseverance, one of the most important concerned the issue of receding galaxies. By all appearances, Hubble had stumbled onto the fact that ¡¦the cosmos was expanding, flying apart as if it has once been highly concentrated¡¦(Parshall et al, 1998 p.PG). Little did he know at the time, but his discovery would come to represent the big bang theory that has evolved as such a well-known concept within the worldÃÔ contemporary scientific society. Hubble was a US astronomer who studied extragalactic nebulae and demonstrated them to be galaxies like our own. He found the first evidence for the expansion of the Universe, in accordance with the cosmological theories of George Lema and Willem de Sitter, and his work led to an enormous expansion of our perception of the size of the Universe.
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 lights that filled the universe could be channeled, dissected, magnified, and measured by human ingenuity” (enlight, 2). There was a significant breakthrough in regards to what could be done in continuing to explore new theories.
On August 9, 2014 police officer Darren Wilson heard a call on his radio about a shoplifting in progress. It was then that Wilson proceeded on with his day only to encounter 18-year-old Michael Brown and 20-year-old Dorian Johnson were walking in the middle of the street; both of which matched the description of the call that had occurred earlier. The events of that day resulted in Brown’s death. This ultimately aggravated the citizens of Ferguson, who then protested in an effort to stand up for Brown who they believed was killed while surrendering. Considering all the evidence, the grand jury should not have indicted officer Wilson because the witness statements and the autopsy are in favor of what Wilson had reported.
In his novel Puddn'head Wilson, Mark Twain utilizes supremacist discourse and belief system to look at bondage's outcomes and make a request for change for African Americans. Rather than mocking the black race, Twain is pushing for social value by showing how far blacks have fallen. He expected to exhibit the points of view of that local town of Dawson's Landing in Missouri, at the edge of the Mississippi River. Twain's novel can seem like a problem at first, since it is a story about enslavement made practically forty years after the completion of the Civil War. Despite the way that a black man never again expected to fear being sold "down the stream" as Roxy and Chambers do, simply because of the complexion of their skin (Watson, 2011).
This observation means that it has taken every galaxy the same amount of time to move from a starting position to its current position. This observation is called "Hubble's Law," named after Edwin Hubble (1889-1953) who discovered this in 1929. Edwin Hubble’s evidence supports the expansion of the universe and suggests that the universe was once compacted. Third, if the universe was insanely hot as the Big Bang suggests, scientists should be able to find some of this heat left over. In 1965, Arno Penzias and Robert Wilson discovered a 2.725 degree Kelvin Cosmic Microwave Background radiation which infuses the observable universe. This is thought to be the remnant that scientists were looking for. Finally, the discovery of great amounts of Helium and Hydrogen lead to support the Big Bang Theory. (LaRocco)
In 1920, two astronomers named Harlow Shapley and Heber Curtis had a big public debate. They argued about a lot of things, but the main thing they were arguing about was the size of the Milky Way and whether or not there were other galaxies like ours in the universe. Shapley had figured out that the Milky Way was a lot bigger than people thought before, and he was right, but because of that he also believed that there couldn't be other galaxies like ours out there. Curtis, on the other hand, thought the Milky Way was smaller than it actually is, but argued that there might be other galaxies like ours out there.
Genetic disorders range from minor to extreme. While some disorders can enable a person to live a full life, some are much more devastating. “Wilson’s disease is a rare inherited disorder that causes too much copper to accumulate in your liver, brain, and other vital organs,” says Mayo Clinic. 1 Wilson’s disease can enable a person to live a long and healthy life, if they seek out treatment.
Have you ever seen someone with walking or speech difficulty? If so that person might have a rare disease called Wilson disease. Wilson’s disease is a genetic disorder where copper builds up in your body, and your body can’t get it out. This disease is passed on from your parents, so if your one of your parents have it you have a good chance of getting it. There's no way to prevent it but many was to get rid of it.
A second key detail from the debate is the discovering of what nebulae really are and where they are located as well. This is important because it allows us
Progressive hepatolenticular disease, or more commonly known as Wilson’s Disease, is a rare autosomal recessive genetic disorder of copper metabolism that is characterized by hepatic and neurological disease. While there is no cure for Wilson’s Disease, there are several treatments that can effectively manage the symptoms. The predominant form of treatment for Wilson’s Disease is heavy metal toxicity medication which utilize copper chelators to prompt the organs in the body to release copper into the bloodstream and excreted via urine after kidney filtration or zinc to reduce copper absorption (Ala et. al, 2007). Medications for Wilson’s Disease include penicillamine, trientine, and zinc acetate. Besides medications, other current therapeutic
These pieces of evidence are some of the evidence that the supernova and gas theory has backing it up. Of course, because it is considered a legitimate theory, there is a lot more evidence backing it up, but this is some of the most recent. Perhaps it is not the absolute most recent, but it is close. After all, we didn’t know that titanium or aluminum-26 wasn’t present at the beginning of the universe until only recently. But, with this new evidence, it is clear that this was the case, and so, the supernova and gas theory is still
Once microwave radiation was discovered, studies improved on the Milky Way Galaxy. Its Doppler Shift can be used to map the motion of gas in it. Also, with radio telescopes, hydrogen gas can now be traced. When the Hubble Space Telescope was introduced in 1990, that made exploring space so much easier and more efficient. That’s how we discovered so much about our universe- including galaxies!
