The speed of light in a vacuum is approximately 299,792,458 meters per second, which is about 186,282 miles per second. This is a universal physical constant and is denoted by the mathematical symbol 'c'. Note that the speed of light will vary depending on the medium it travels through, but in a vacuum, it is always constant. Additionally, while the speed of light is very fast, there may be physical limitations that make it difficult or impossible for humans to travel or communicate at such speeds.
