Document Summary
Chapter 1: scienti c theory & the big bang. A hypothesis (plural: hypotheses) is an educated guess based upon observation sometimes, only one observation. Usually, a hypothesis can be supported or rejected through experimentation or more observation. While it can be supported or rejected, it cannot be proven to be true. A scienti c theory summarizes a hypothesis (or group of hypotheses) that is supported by repeated testing and observation. A theory is considered valid as long as there is no rm evidence to dispute it. So, like hypotheses, theories can also be supported or rejected as we learn more. Basically, if evidence accumulates to support a hypothesis, then the hypothesis becomes accepted as a good explanation of some phenomenon, and becomes a theory. The theory is not guaranteed to be true, but it is the best we can formulate based on current evidence.
