Exploring light speed opens the door to some of the deepest questions in physics. These posts look at why the speed of light is not simply how fast light travels, but a fundamental limit connected to space, time, gravity, energy, and cause and effect. From Einstein’s relativity and time dilation to black holes, distant starlight, cosmic distances, and the question of whether anything could ever travel faster than light, this category examines why light speed sits at the heart of how the universe works.
