James Clerk Maxwell theorized that electromagnetic waves, such as light, travel through space at the speed of light, which is approximately 299,792 kilometers per second in a vacuum. This speed is a fundamental constant of nature and plays a crucial role in various branches of physics, including electromagnetism and relativity.
