Part 1: Challenges of making direct measurements
Physical science is often viewed as the model of sound knowledge. Physical science represents a body of knowledge that has verifiable information. Physical science concept represents knowledge which has resulted after research and experiments on different scientific theories. During the development of such knowledge, measurements are made. Challenges in measurement are often related to the efficacy of the measuring tools being used. Challenges in measurement are as a result of lack of a direct method of measuring.
In astronomy, the scientists face a number of challenges such as measuring the distance between stars, the mass, and components making up
