…types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge…
Visual representation of a Schwarzschild wormhole. Wormholes have never been observed, but they are predicted by mathematical models in general relativity.
