Document Summary
Chapter 1 : scientific theory and the big bang. Can be supported or rejected through experimentation or more observation, but cannot be proven true. Scienti c theory: summarizes a hypothesis that is supported by repeated testing and observation. To tell the difference between a theory and a law, as if the statement explains why something happened. If it describes how something happens, it is a law. Before the big bang, the universe did not exist. At the birth of the universe, time and space were created in a gigantic expansion that emanated from a singularity, and there was nothing: no space, no time, no energy. Singularity: is said that an area in space-time where gravitational force is so high that all known laws of physics break down and do not apply. Gigantic expansion: not the equivalent of a gigantic explosion. To have an explosion there must already be space present for which the explosion can spread into.
