ght did not require a medium in which to travel in wave form. Light was also proven to travel at a constant speed under any conditions and from any perspective (Spangenburg 21).At the onset of the 20th century, physics reached a new level of complexity, ranging from a deeper understanding of quantum physics to the newly innovative nuclear physics. Physicists such as Einstein, Oppenheimer and Bohr made their mark in scientific history. Each of these paradigm pioneers left behind landmark inventions such as the atomic structure, theory of relativity and the atomic bomb. More accurate documentation of these discoveries will surface as time progresses.As we are just beginning this promising 21st century, there are endless possibilities waiting on the horizon. It is difficult to guess what exciting changes are in store for us in our great big beautiful tomorrow. ...
