U08d1, u08d2, u08d3 - Coursework ExampleThe Sun is notmassiveenough to ever evolve into a black snare it will end its animation in about 4.5 billion years as a white dwarfstar. however, in case if the Suns mass was suddenly died into a black hole then Earths orbit then if a onesolar massblack 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 only 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 galaxy. That used to be a huge number. But its only a hundred billion. Its less than the study deficit We used to call them astronomical verse game. Now we should call them economical numbers. Richard Feynman, American physicist, Nobel Prize honourable When we think of an astronomical number we probably think of a sum 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 say that there are at least 100 billion galaxies in the universe and for each one galaxy containing around 1 trillion stars. Thats 1 x 1023 or 100 sextillion stars in the universe. Hence this comparison is through 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 trying 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 over in daily life are growing steadily larger. While the consumer was busy saving, the Federal U. S. government was piling on debt at a more greater pace. In fact, during Q2 of 2008 Washington accumulated debt at a 24.4% annual rate Therefore, even though households and state and local governments have hopefully begun to ingest 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 nebulae or stars form from thegravitational collapseof gas in theinterstellar medium. As the material collapses under its own weight, massive stars may form in the center, and theirultra violet radiation ionizesthe surround gas, making it visible at opticalwavelengths. Star formationis the process by which dense parts ofmolecular cloudscollapse int o a ball of germ plasmto form astar. These eerie, dark pillar-like structures are actually columns of cool interstellar hydrogen gas and dust that are also incubators for new stars. The pillars protrude from the intimate wall of a dark molecular cloud like stalagmites from the floor of a cavern. They are part of the Eagle Nebula M16, a nearby star-forming region 7,000 light-years outside(a) in the
