2. Copyright © 2014 All rights reserved, Government of Newfoundland and Labrador Formation of the Universe Unit 1: Topic 2.1 Focus on...   Recognize differing ideas regarding the origin of the universe: ex. Creationism  Describe the origin of the universe as described by the Big Bang Theory

3. Copyright © 2014 All rights reserved, Government of Newfoundland and Labrador Origin of the Universe Throughout history many ideas about the origin of the universe was hypothesized. These ideas range from; Creationism - where some supreme being (God) created the universe, to more scientific views such as The Big Bang Theory. Regardless, early ideas (paradigms) changed with time as new evidence was discovered to change initial models and theories of the universe.

Copyright © 2014 All rights reserved, Government of Newfoundland and Labrador Big Bang Theory: This theory explains the origin of the universe and suggests that the universe, our solar system included, is part of an expanding system where all galaxies are moving farther away with each passing day.

5. Copyright © 2014 All rights reserved, Government of Newfoundland and Labrador Big Bang Theory in a Nutshell...  universe was confined to a dense, hot, super massive ball of gases  20 billion years ago, an explosion hurled this material in all directions  marked the origin of all matter and space

6. Copyright © 2014 All rights reserved, Government of Newfoundland and Labrador Big Bang Theory in a Nutshell... (Con’t)  gases cooled and condensed forming stellar (stars) systems that we call galaxies  20 billion years in the future, the expansion will stop and gravitational attraction would follow where stellar material will collide to form a new hot, dense fire ball and the process starts again
