Speed of light is 186,282.3976 statute miles per second in vacuum.
If I could expound on this,
the speed of light is the only constant in the universe. Furthermore, it is the same for all observers, no matter how fast they themselves are moving or how fast the object that is shining the light is moving.
Light can be bent by a massive object. This was tested during an eclipse shortly after Einstein came out with Relativity.
This is purported to be a
partial list of Universal Constants. What's Up?
