Eli5: Why does light travel so fast?
In: 130
The speed is so fast because light is a type of electromagnetic radiation, and it is able to travel through a vacuum without encountering any resistance or other obstacles that would slow it down. Additionally, the speed of light is the maximum speed at which information can be transmitted in the universe, according to the theory of relativity. This means that light is able to travel extremely quickly because it is not limited by the same physical constraints that affect other forms of matter and energy.
