If you travel parallel to a car, at the same speed, you will see it at rest. If you swim at the same speed as a wave, you will see it at rest. If you travel at the speed of sound, and airplanes can do this, you will also “see” it at rest. But if you could travel at the speed of light, holding a flashlight, you will see that radiation traveling at the speed of light, 300,000 km/s, and not at rest. Again, it doesn’t matter if you turn on a flashlight at rest or moving very fast. The speed of light is always the same in any reference frame. But why? What is so different about light? Let’s map and scale our knowledge together to try to understand one of the most mysterious questions in the universe.
