Is There Anything Faster Than the Speed of Light? In theory, it seems that nothing is faster than the speed of light, or is there? Let’s find out. If you traveled around the Earth with the speed of light, you would make a complete tour of our planet 7.5 times in just one second. However, if our spacecraft would be traveling at the speed of light, we would reach the Sun in only 8.3 minutes. If you want an example of how fast the speed of light is, think about this, if we were to launch an imaginary spacecraft from Earth that would travel at around 153,454 mi / 246,960 km per hour constantly, it would reach the Sun in 606 hours, or 25 days. It seems that nothing can be faster than the speed of light. In water, the speed of light is slower, at 225,000 km / 139,808 mi per second, and 200,000 km / 124,274 mi per second in glass. In terms of seconds, light travels at around 300,000 kilometers per second or 186,000 miles per second in a vacuum. In miles per hour/mph, the speed of light is at around 670,616,629, while in kilometers per hour, light travels at 1,079,252,848. The speed of sound travels at around 343 m/s, while the speed of light travels at 299,792,458 m/s. With our current understanding of motion, it seems that the speed of light is the highest of all, being 874,030 times faster than the speed of sound.
