The spacetime geometry of the Universe which drastically restricts the set of cosmological models compatible with general relativity, the mass and flatness 4. The Hubble Law which states that the universe is always expanding. Flat model universes are infinite and expand forever and modern observation shows that the universe is flat. The expanding universe must have begun from the moment of extreme conditions where the matter and energy of the universe compressed into a high-density, high-temperature
2. Temperatures in the corona can reach over 1 000 000 ̊C. 3. It is the thickest layer, stretching several million kilometres into space. Phenomena on the Sun’s surface | 1.
These are the largest of Jupiters moons. He also saw that Venus has phases such as our moon does. This discovery, that Venus has phases, of Galileo helped proved that Venus orbits the sun. With all the discoveries Galileo was finding, more and more people came to accept the heliocentric model. Many people referred to the change of their view point of the universe as the Copernican
Caitlyn Hammond November 7th, 2011 The beginning of the end In ancient times, the Greeks relied heavily on their gods to explain the natural phenomena happening around them. The sun rose and fell when Apollo drove his chariot across the sky, the ocean was controlled by Posiden and the Heavens by Zeus. However, not all Greeks were satisfied by this explanation. Out of this, grew the Pre Socratic philosophers and more importantly the material monists. The three material monists are considered the first "Physicists" because they were the first to attempt to explain the natural phenomena without reference to the divine.
The teleological theory offers no scientific evidence, or evidence of any kind for the creation of the universe, it is based loosely on an analogy. The analogy opinion is too broad to be valid. I believe that things like volcanos and earthquakes that happen naturally are better explained by science. These things seem more probable in a universe that was created randomly by science, by the big bang, than if the universe was created specifically for a certain function by
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.
How does cosmology differ from astronomy? Cosmetology studies the birth and the possible deaths of the universe where as astronomy studies the actual objects in the universe What is a galaxy? How are galaxies distributed in the universe? A galaxy is a collection of billions of stars and gasses being held together by gravity. Name the different types of galaxies and their distinguishing characteristics.
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’.
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. 
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.
