Universe 1. What is Earth’s Sun‚ and what is its role in the solar system? 2. What is the Milky Way galaxy and the sun’s position in it? 3. What is the Big Bang‚ and what does it say about the age of the universe? 4. What is meant by the phase “looking out in the universe is looking back in time?” 1. The earth’s sun is a star‚ it generates heat and light through nuclear fusion. 2. The Milky Way galaxy is the constellation that earth belongs to‚ the sun is just another star within it. 3. The big

That’s ridiculous. And creation cannot come without a cause. They base this theory on coincidence. I think it’s absurd for someone to believe that this is all plain coincidence. Was it just a coincidence that this timeless “bang” arranged our galaxy in such a rational way that there is an orbit system? Is it a coincidence that all elements present on this planet can perfectly and unconditionally support human existence? Was it coincidence that crafted the intricacy of life? Was it just innocent

1) Shapley’s three-dimensional view of the distribution of globular star clusters is represented by a sphere centered on galactic center. A)True B)False 2) Shapley concluded that the Solar System couldn’t be located at the center of the galaxy. He observed : A) an even distribution of globular clusters in all directions. B) more globular clusters in certain directions. C) an uneven‚ random scattering of globular clusters across the sky. 3) Since the stars inside the horse’s head in

that not even time‚ mass or length are constant – they vary according to our perspective of them. Edwin Hubble He began a painstakingly slow observation of nebulae‚ small patches of light that appeared outside our galaxy. Edwin Hubble discovered that these nebulae were in fact galaxies like our own‚ millions of light years away from us‚ which proved that the universe was vastly larger than had previously been thought.

black holes- stellar and super massive. Stellar sized black holes are the remnants of massive dead stars that have imploded. It is estimated that our galaxy contains millions of these stellar black holes. Super massive black holes can have a mass millions of times that of the Sun. It is believed that these massive holes are in the center of every galaxy. There may be mini black holes‚ smaller than atoms in volume but as massive as whole mountains. There are some black holes lying between stellar and

exchanging energy with the fundamental particles. This could no longer take place so easily with atoms so the photons filled interstellar space in the form of almost a ’gas’. Over a period of 10 billion years this matter and energy coagulated into stars‚ galaxies and planets and continued to expand‚ forming what we now know as the universe. The big bang theory was initially suggested by Georges Lemaitre in 1927. His proposal came after comparing a model of the universe based on Einstein’s theories with observations

First‚ he discovered the existence of far of galaxies and was able to show the galaxies in all stages of evolution (amazingspace.org). These galaxies had never been discovered or seen before this. The Hubble space telescope also helped answer how rapidly the universe is expanding and for how long. Thanks to the Hubble telescope we were able to determine

What are the four major features of our solar system that provide clues to how it was formed? Describe each one briefly. Four major features provide clues: (1) The Sun‚ planets‚ and large moons generally rotate and orbit in a very organized way. (2) With the exception of Pluto‚ the planets divide clearly into two groups: terrestrial
