Yes, according to our current understanding of physics, the speed of light in a vacuum is the same for any direction. This principle is known as the isotropy of the speed of light. The famous physicist Albert Einstein's theory of special relativity postulates that the speed of light in a vacuum, denoted by the symbol "c," is constant and does not depend on the motion of the source or the observer.
Experiments and observations have consistently confirmed this prediction. Regardless of whether the source of light or the observer is moving towards or away from each other, the measured speed of light remains constant at approximately 299,792,458 meters per second (or about 186,282 miles per second).
This constancy of the speed of light is a fundamental principle of modern physics and has significant implications for our understanding of space, time, and the nature of the universe.
