Why+can+we+see+them?

Why can we see them? We can only see stars because the light is reflected from the sun, which allows us to see the stars and sun. This is called light spectrum. It travels in wavelengths at the speed of light which is 299,792km/sec. Speed of light (which is usually denoted as 'c' e.g. E=MC^2) means that it takes the sun's light to travel to earth, 8 minutes and 19 seconds //(approx)//.
