The Milky-Curtis Debate Analysis

At first glance, one might think that nebulas are made of light and that they have no

That the universe extended beyond the Milky Way was already widely surmised, and this discovery didn't change much. The revolution came when Hubble compared these newfound distances with the velocities of galaxies, which can be determined by measuring their color spectra. To his surprise, he found the two to be nearly linearly correlated, leading to the conclusion that every galaxy is receding from every other galaxy, and the universe as a whole is expanding.

These ideas not only, obviously, created a new conception of the forming of the universe, but also of humanities place within it. The Copernican hypothesis had enormous religious implications as it destroyed the idea that the earth was different from where God was. This eliminated the realm of perfection. Therefore humanity’s place within the Earth was lessening in importance. Also, 1572 a “new star,” which was really an exploding star, left a huge impression on many people. This is because it contradicted the idea that the heavenly spheres were unchanging, thus

In document 2, “The Church taught that Earth was placed by God in the middle of the universe… Copernicus reasoned that indeed, stars, the earth, and other planets revolved around the sun” clearly states the difference between the Church’s teachings and Copernicus’ new theory. This was the issue. This new theory confused people because it was so different than the information they were previously taught by the Church. Scientists, like Galileo or Kepler, started to research and continue supporting Copernicus and his ideas. Many discoveries due to this idea proved that the Church was wrong- which caused disagreements between the scientists and the Church.

One display of the conflict is shown in the novel when Howard is defending himself in court. Howard argues,” But the mind is an attribute of the individual. There is no such thing as a collective brain. There is no such thing as a collective thought. An

19. What is the scientific method, and how does it relate to the science of astronomy?

The main topic of discussion in the re-argument was whether or not segregation in schools violates the fourteenth amendment. Consequently the court did not base there final decision on how the Fourteenth Amendment should be interpreted but solely on how segregation effected colored students and if colored students were treated equally.

Shapley's contender, Heber Curtis, argued that the Milky Way was not the only galaxy in the universe. He believed that other, far more vast galaxies, existed as well. His counter-evidence was in the spiral nebulae found outside the Milky Way galaxy. However, his evidence was not solid enough to back his claims, which was based on the assumption that the way the nebulae were shaped made it impossible to see around them, or beyond them.

What did the court decide and why did it decide the way it did. There may also be some justices who disagree with the majority. This is the dissent. Briefly summarize why they dissented. Be sure to state how many judges were for or against the decision.

[27] Scientists can determine what a distant star is made of by looking at ____.

Capital Budgeting encourages managers to accurately manage and control their capital expenditure. By providing powerful reporting and analysis, managers can take control of their budgets.

She is most notable for providing a great deal of compelling evidence, alongside Dr. Kent Ford, that proved Fritz Zwicky’s Theory of the existence of Dark Matter.2 Zwicky stated that individual galaxies within the Coma Cluster were moving so fast that if they were only held by the gravity of its visible mass that it would escape. Since he found no evidence of the cluster falling apart he concluded that there must be something else holding it together that was nearly 10 times that of visible matter, he called this Dark matter.2 While working with Dr. Ford, they began analyzing the light coming from stars in spiral galaxies. They used what is called the “Doppler effect” which states the wavelength shift is proportional to the speed of the light source relative to the observer. This uses the wavelength of light in how it is approaching or moving away from the observer. When a light source moves away from you it presents a red color and when it comes toward you it presents a blue light. After measuring several stars in different parts

The Orion Nebula contains one of the brightest star clusters in the night sky. With a magnitude of 4, this nebula is easily visible from the Northern Hemisphere during the winter months. It is surprising, therefore, that this region was not documented until 1610 by a French lawyer named Nicholas-Claude Fabri de Peiresc. On March 4, 1769, Charles Messier inducted the Orion Nebula, M42, into his list of stellar objects. Then, in 1771, Messier released his list of objects for its first publication in Memoires de l'Academie.1

A galaxy, also called a nebula, consists of billions of stars, interstellar gas, dust, and dark matter which are all bound to form a massive cloud in which we live in. Although it cannot be very well explained, dark matter makes up at least 90% of a galaxy’s mass.

2) Through practice Galileo became good to observe the stars and was able to identify craters on the moon.
