The essence of Einstein’s world lies in the concept of relativity. He described it once in the following way: “When you sit with a nice girl for two hours, it seems like two minutes. When you sit on a hot stove for two minutes, it seems like two hours; that’s relativity he said. “Einstein also boldly stated that there are no absolute quantities, that the magnitude of quantities depends on the relative velocity between an object and the observer, and that every event and measurement is viewed differently depending on the observer’s velocity. However, the only measurement that remains constant is the speed of light C in vacuum. The astounding results of his Theory of Special Relativity indicated the following. If an object neared the speed of light, then:
