* Relativity: The speed of light in a vacuum (approximately 299,792,458 meters per second) is a fundamental constant in the universe. It's the maximum speed at which information or any object with mass can travel.
* Frames of Reference: The speed of sound depends on the medium it travels through (like air, water, or metal). It's a relative speed, meaning it changes based on your frame of reference.
Imagine this: You're standing still, and a supersonic jet flies past you at a speed greater than the speed of sound. Even though the jet is traveling faster than sound, the speed of light is still the same.
In short: The speed of light is the ultimate limit, and nothing can travel faster than it. Adding the speed of sound to it wouldn't change that fundamental principle.
