3.4 Implications

The terrestrial determination of the speed of light by Fizeau’s experiment is of great importance in the sense that it forms the basis for the modern theories of physics. Although still being investigated, such theories postulate that gravitational particles (waves) travel at a speed equals to that of light. Such theorization is critical in studying gravitational waves’ effect based on colliding neutron stars and black holes. From a theoretical perspective, the waves can only travel at a speed close to that of light but cannot exceed it.

Similarly, the time-travel theories are based on the speed of light. Time travel is a concept that denotes travelling between two different points in time rather than in space. Such theories have dominated sci-fi movies, in which humans are able to get in some kind of spaceship and arrive in the future or past. For one to accomplish time travel, the spaceship must travel at a speed close to that of light. In practice, the speed of light has enabled scientists to accurately determine the distance between the Earth and other bodies, including the moon, the Sun, and the stars.
