    What is the relationship between light and time ?

    Could light actually be time ?

    Sorry if its a very naive question. I will be grateful for all responses.

    No, light and time are not even remotely the same thing and the only relationship is that time is used to measure the speed of light. Time is a dimension. Light is a quantum object.

    Well, I need light to see my watch. (OK, kidding.)

    There is a connection between the speed of light, which is a kind of cosmic speed limit, and the nature of time. That connection is detailed in Einstein's special theory of relativity.

    That doesn't really make sense.
