U08d1, u08d2, u08d3 - Coursework ExampleThe Sun is non largeenough to ever evolve into a black hole it will end its life in about 4.5 billion years as a white dwarfstar. But, in case if the Suns muss was suddenly collapsed into a black hole then Earths orbit then if a onesolar stackblack hole were to suddenly replace the Sun at the center of our solar system, the orbits of the planets would not change. This is because the physical laws that determine the orbital motion of the Earth depend still on the actual mass of the Sun, and not on whether it is distributed within a sphere (like the Sun) or at a point (like a black hole). 2. There are 1011 stars in the coltsfoot. That used to be a huge number. But its only a hundred billion. Its less than the national deficit We used to hollo them astronomical numbers. Now we should call them economical numbers. Richard Feynman, Ameri crowd out physicist, Nobel Prize Laureate When we think of an astronomical number we probably think of a s um thats almost beyond human comprehension. We probably refer to huge numbers as astronomical because of the vast and seemingly infinite universe. But the universe may not be as big as it seems when compared to something like the national debt. This quote has been said towards the backhanded critique of government. Furthermore,we can dictate that there are at least hundred billion galaxies in the universe and each galaxy containing around 1 trillion stars. Thats 1 x 1023 or 100 sextillion stars in the universe. Hence this comparison is done against the size of the national deficit. Its a good point, and economics can provide some slightly more familiar analogies to people grappling with large numbers than essay to contemplate entire galaxies. The important point here is not that high finance is catching up with the sciences its that the numbers we encounter everywhere in daily life are growing steadily larger. While the consumer was busy saving, the Federal U. S. government was piling on debt at a much greater pace. In fact, during Q2 of 2008 Washington accumulated debt at a 24.4% annual rate Therefore, even though households and suppose and local governments consecrate hopefully begun to learn their lessons D.C. still managed to increase the overall level of non-financial debt in the U.S. to a record $35.45 trillion. 3. Picture of the week How are the stars formed within the nebula? What is causing these dramatic pillars? What thoughts and reactions do you have to the pictures and their descriptions? All stars are formed from nebulae (the plural of nebula). Nebula is a term for a cloud of gas, and stars form from gas. many an(prenominal) nebulae or stars form from thegravitational collapseof gas in theinterstellar medium. As the material collapses at a lower place its own weight, massive stars may form in the center, and theirultra violet radiation ionizesthe surrounding gas, reservation it visible at opticalwavelengths. Star formationis the process by which dense parts of molecular cloudscollapse into a ball ofplasmato form astar. These eerie, dark pillar-like structures are actually columns of assuredness interstellar hydrogen gas and dust that are also incubators for new stars. The pillars protrude from the interior argue of a dark molecular cloud like stalagmites from the floor of a cavern. They are part of the double birdie Nebula M16, a nearby star-forming region 7,000 light-years away in the
