The speed of light is 299,792,458 meters per second and that constant tells us much about cause and effect in the universe.
Even though the density of interstellar space is billions of times lower than even our emptiest human-made vacuum chambers, it's not 100% percent empty.

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light.
