Modern physics involves the theory of relativity, which describes how time, space and gravity are not constant in our universe can be different for different observers, and quantum mechanics, which describes the… Physics is the most fundamental of the sciences, concerning itself with energy, matter, space and time, and their interactions

Physics is the basis for all other sciences, such as chemistry, biology and geology, because physics describes the fundamental way in which the universe functions The processes of science include observation, hypothesis, experiment, and conclusion

physics — science aimed at describing the fundamental aspects of our universe—energy, matter, space, motion, and time. theory — explanation of patterns in nature that is supported by much scientific evidence and verified multiple times by various groups of researchers. theory of relativity — theory constructed by Albert Einstein which describes how space, time and energy are different for different observers in relative motion. scientific law — pattern in nature that is true in all circumstances studied thus far.
