Speed of Light
The speed of light remains constant for all observers in a vacuum, a principle that leads to the intriguing paradoxes of special relativity. Light, along with gravitational waves and other massless particles, travels at approximately 300 million meters per second, but no object with mass can reach this speed. Understanding this speed limit is crucial for grasping the fundamental laws of physics and the nature of our universe.In this clip
