In a closed room , a candle lights up a certain area. Or a tubelight lights up the room. Intensity of light or light just got scattered? We will differentiate it cause it's scattered equally in the room which has a finite area. Am I right?
Sun's light is not infinite. It's finite ( it's reducing or remaining in equilibrium) according to me. But feels like integration. We have a speed of light, C. But light is a derivative. lt's in motion, so derivative.
If time had speed, rate of change of time - which l intuitively feel can be determined.
