The correct statement is:
**Light can travel in a vacuum, and its speed is constant even if the light source is moving.**
This aligns with the principles of special relativity, which state that the speed of light in a vacuum is always constant (approximately 299,792 kilometers per second) regardless of the motion of the source or the observer.
