Science is an organized enterprise which builds and orchestrates knowledge in the form of verified predictions and testable predictions about the universe and its various constituents. It is based on the assumption of the uniformity of nature and the sequence of nature’s events. It attempts to describe the universe in terms of measurable facts, while making such observations as are necessary for obtaining this information. The observations and the results of such endeavors are using to support the predictions which are then used to understand the nature of reality and make possible the predictions which are required for taking action.

One of the main concepts in science is the law of cause and effect, which according to Webster’s Dictionary is “A law by which cause and effect may be discerning to happen beforehand or after a specific time and in any special way.” According to James Clerk Maxwell the law of cause and effect are “the means whereby the phenomena of a body can be substituted for those results derived from observation.” The hypothesis of a cause and effect relation then becomes a law. If we use this definition to analyze science we can see that it is dependent upon a prior understanding of how to determine the presence or absence of independent variables. A hypothesis therefore is a supposed truth which can be tested, either by observation or by hypothesis. The hypothesis therefore is a contingent true or false idea.

Science has many methods of investigation, each with its own strengths and limitations. In the field of pure science such as physics and chemistry, the hypothesis has great importance because it is necessary to rule out all other possibilities. The naturalist theories of evolution, or the belief in the uniformity of nature, are based on the hypothesis that there must be some laws of natural phenomena. Another example of a hypothesis in science is the Laws of Thermodynamics, which state that the total amount of energy in a system will always remain the same unless it is changed by an outside force. Another example is the Standard Model of particle physics, which is the theory of particles having no other properties than their position and time.
