Why is light the fastest thing ever?

Light travels at the speed of 300 000 kmph or about 180 000 mph, which is a LOT. In fact, any object with mass cannot travel at that speed as you’d need to spend a infinite amount of energy to accelerate a body to that speed.

The fact that light, when stationary, is without mass allows light to travel only and only at the speed of light. In fact, any object that has no rest mass will travel at the speed of light.

Now you know why light is the fastest thing ever.
