Astronomy 1a b).The assumptions used by Hubble He used a standard ruler assumption which assumes that all galaxies in the universe are of the same size and type for uniformity. Another assumption was that the smaller and fainter the galaxy is, the longer the distance it is and faster move from us. The velocity (v) = Ho d whereby v is the velocity, d is the distance to and Ho is proportionately constant. All the zero age main sequence stars start at the same luminosity given temperature.
2. Andromeda galaxy as spiral nebula and Andromeda galaxy with spiral were all small bodies that were part of the Milky Way. He believed that everything in the space was located within the galaxy. Shapley advocated a proposition of relative size to support his idea that if the Andromeda galaxy had not been part of the Milky Way then the distance of it could have been 1000000000 light year. This research was not fully welcomed by most of the scientists during the period. The Andromeda spiral almost sparkled at an era of time in the Andromeda galaxy. Outwardly and for new star, the gross energy was not reasonable.
Consequently, the Andromeda and new star should be in Milky Way. The evidence showed optical spectrum of the spiral nebula was not distinguishable from spectrum of the galaxy. Shapley also utilized the kind of absurdum and reduction fully. If Andromeda had been independent, then it had possessed a miraculous brightness so that people could have detected from far.
3. Andrew McKellar was a Canadian astronomer, who studied physics and mathematics in the University of British Columbia. He showed his first observations to astronomers in 1930 and early 1940s. He suffered a number of setbacks that made him not to realize it. One of the setbacks was non-uniformity in observations. This was due to coherent fluctuations on angular scales that were larger than cosmological horizon at combination. Instrumental errors due to the use of different instruments were another major cause of difficulty in data collection. Planck telescope which was more sensitive and had larger angular resolution confirmed the axis of evil observation. Non- equivalent dependent variable designs used by Andrew McKellar hindered effective collection of data. Read More

...Homework In the disasters you saw in the photographs, what should the buyer have insisted upon in his/her contract with regard to risk of loss? Explain. Ocean freight has been one of the most utilized modes of shipment throughout the globe as it is cheaper and it can transport any size or weight of goods. Unfortunate for some, this method involves risks such as occurrence of unprecedented disasters, accidents, or malfunctions of these cargo ships. Such cases lead to filing of law suits on the part of the cargo’s insurance companies and on both parties of buyers and sellers. In circumstances such as the ocean disasters reflected in the photographs, the buyer should have included a condition subsequent (Mallor, et al., 2012... In the disasters ...

... Affiliation Cost estimation is an important aspect of project management and determines whether the project is worth undertaking, whether it will be profitable to the company, and if at all the company can afford it (Pinto 2010). It provides the firm with a cost range (“Ball park estimate”) of the total monetary cost of the project. In terms of project schedule and Work breakdown structure, it leads to budgeting for monetary, human and material resources since the management eventually uses these allocations to coordinate the resources to ensure all three are available when needed. Parametric cost estimation works for cost estimation because it is more accurate as compared to analogous cost estimation (Pinto 2010). Considering... Affiliation ...

It is supported by the hypotheses of cosmological constant and quintessence. Each of these provides an elaborate argument for its existence. Question 4 There is a very big difference between the top-down and bottom-up processes in the formation of galaxies and other structures. In top-down, the galaxies are formed when the dark...

... Assignment Question When massive stars explode, they leave remnants, which are a few times, the mass of the sun. Large fractions of the materials resulting from the explosion are thrown outward at massive speeds. As the material sweeps through the surrounding gas, heat and shock radiate which leads to the production of arcs and rings seen in the pictures. The high energy, which went into the explosion, leads to the production of a supernova remnant. The initial expanding shell contains the outer parts of the exploding star, which move at high speeds of approximately 2000 to 10000km s-1 (Yockey and Hubert 112). The shell becomes more massive as it sweeps the surrounding, it, therefore, slows down. The remnants of these explosions... Assignment...

... Assignment, Astronomy Question Supernova occurrences in our galaxy are relatively rare, occurring about three times a century in the Milky Way. The last directly seen supernova was Kepler’s star of 1604 (SN 1604). Since the last directly observed supernova of 1604, it has been about five centuries an indication of deficiency in supernova rates in our galaxy. From these observations, an occurrence of another supernova is long overdue. Question .2 The theory based on extraterrestrial source proposes that the icy comets, meteoroids and other primordial objects rich in frozen water and water of formation that collided with earth which lead to the release of the largest proportion of waters on earth’s surface. This theory however, fails...

... Rare Earth Theory The Rare Earth Theory suggests that the emergence of complex multi-cellular life on Earth requires an improbable combination of geological and astrophysical circumstances and events. The theory argues that complex extraterrestrial life is likely to be extremely rare and is very improbable phenomenon. It goes ahead to presume that planets like Earth with complex life are not common in the Universe. Many scientists have backed the theory arguing that the Earth formed nearly 4.5 billion years ago yet complex life has only existed for about 500 million years. It remains unclear what chain of circumstance led to the emergence of life on Earth. However, scientists believe that the long period of relatively stable... Rare Earth...
