- Astronomy Question: Read the questions slowly and answer with precise and long details about each of the questions. Answer correctly and follow my guidelines for a long and wonderful review after results. Your target/main observable galaxy is the whirlpool galaxy. Target: Whirlpool Galaxy Object Type: Galaxy Distance: 37 million light-years Constellation: Canes Venatici. DO NOT COPY AND PASTE OTHER WORK OR THINGS FROM THE INTERNET, use your own words. In 500 words, please explain the relevance of this object to the physics course material in university andits importance to astronomy. (Some question you may seek to answer are: What beyond the objectitself is learned by studying this class of objects? What sorts of telescopes and observations would beneeded for more detailed, broader reaching studies of this source and objects of its nature?)Please solve exact and complete question number-1 with three sub-parts. WILL RATE IT UP!! thanks.Need help with one circled
- Explain the expanding Universe theory and its relationship to the Big Bang theory?Why is dark energy required to explain the universe as we see it today according to the Big Bang model of the universe? 9Please answer the second question(everything in the bottom sentence.) please explain how you reached your answer.
- Briefly explain what is meant by “particle horizon” and “event horizon” in cosmology. Calculate the physical particle horizon, RH(t), at time t. Assume a flat FRW universe whichis dominated by a fluid that gives rise to scale factor evolution where n is a constant with 0 < n < 1, and a(t0) = a0.Read the questions slowly and answer with precise and long details about each of the questions.
