The speed of light is 186,000 miles per second, or approximately 670 million miles per hour. Nothing in the universe travels faster than light: at the speed of light, time stops. No matter how fast you are moving when you observe it, the speed of light will always be 186,000 miles per second. In physics, the three dimensions of space and the fourth, separate dimension of time combine to form a single construct throughout the cosmos called space-time. Using space-time, scientists can measure both the pla...
