Astronomy 10 Chapter 11 1. Both used to be normal stars but the white dwarf ran out of hydrogen, they are both subjected to gravitational theories. A Neutron star is a fluid of neutrons, as hot at its surface as the inside of the sun and has a greater magnetic field. 3. Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle.
Physics 1 Unit P1.5 The use of waves for communication and to provide evidence that the universe is expanding * Know and understand that electromagnetic radiations travel as waves and move energy from one place to another. * Know that these radiations can all travel through a vacuum and do so at the same speed. * Know and understand that waves cover a continuous range of wavelengths called the electromagnetic spectrum. * Know that and understand that sound waves and some mechanical waves are longitudinal, and cannot travel through a vacuum. * Know that current evidence suggests that the universe is expanding and that matter and space expanded violently and rapidly from a very small initial ‘point’, ie the universe began with a ‘big bang’.
6. What is CMB radiation? Radiation emitted by the Big Bang, which now has caused a much bigger wavelength because of the expansion of the universe. 7. Which theory is supported by the following evidence- h) red shift-both i) the cosmic microwave background radiation-Big Bang.
Major Contributors to Astronomy Tycho Brahe is known for his accurate and comprehensive astronomical and planetary observations.Tycho Brahe was a Danish nobleman that made vital contributions to astronomy by inventing instruments to observe the sky before the invention or the telescope. In ancient times, Greeks believed that the sky was unchanging and that the stars they saw in the sky had been there since the beginning of time. On November 11, 1572 Tycho saw a star in Cassiopeia that he had never seen before. After a seeing of observations, he realized it was a supernova, which is a death of a massive star. His observations of planetary motion, mostly that of Mars, gave important data for astronomers to come, like Kepler.
Force Fields Summary Response In Michio Kaku’s article “Force Fields”, he explains how a force field can deflect laser beams. Throughout out his article Kaku shows that future science might be able to provide the same technology as science fiction TV shows such as Star Trek because he believes that science would overcome issues of limited technology. In order for force field function correctly he suggests that there has to have three layers. The outer layer is high temperature plasma created by supercharged plasma window. The middle layer is a group of laser beams.
During this revolution, there were many great philosophers who made incredible contributions to science and changed the way people look at the world around them. Polish priest and astronomer Nicloaus Copernicus published his book On the Revolutions of the Heavenly Spheres which assumed that the earth and other planets revolved around the sun instead of the previous belief which said all the planets and the sun revolved around the earth. Galileo Galilei used the first telescope and concluded that the “heavens” were more complex than anyone had suspected. He saw mountains
The idea could be considered as madness but others may say THIS IS PHYICS!  After the giant nebula has started to converge it forms a Protostar, this Protostar is halfway between a nebula and a star. Eventually it gets to a point where it cant contract any more gas and the tremendous pressure starts to cause tremendous hear, and thus nuclear fusion begins, true story. 
The element used in atomic bombs is Uranium-235. Uranium's atoms are unusually large, and henceforth, it is hard for them to hold together firmly. This makes Uranium-235 an exceptional candidate for nuclear fission. Uranium is a heavy metal and has many more neutrons than protons. This does not enhance their capacity to split, but it does have an important bearing on their capacity to facilitate an explosion.
Both briefly touched on the discovery and then focused on more on the American astrologists that confirmed the findings and found some planets of their own. These articles mostly started my look into the subject and will give some brief information, but I also find others that dive more into the topic. By using articles by Walker, Burrows, and Lunine, I will examine the initial reaction of the scientific community in 1995 to this discovery and discuss some of the more technical aspects of 51 Pegasi B. I find it quite interesting how a planet can still exist so close to a sun and with surface temperatures exceeding 1,000 degrees Kelvin. This extreme survivability of 51 Pegasi B was thought to not be possible until its discovery, and now has astronomers rethinking the bases of their planetary understanding. The origin of 51 Pegasi B is also an extremely interesting story, as it is hard to believe that a planet could form so close to a star.
By doing this it was creating huge amounts of Energy. Scientists soon realized that they could use this energy to create very powerful bombs. Scientists started working vastly to create an atomic bomb. In this process they found that a rare form of Uranium was needed to create explosive chain reactions. This uranium was Uranium 235.
