What makes up light
Light is all around us. It’s so fast that to our human eyes it seems instantaneous. However, if you look up at the night sky at the stars you are seeing light that is only just reaching us from millions and billions of miles away. Light, in particular sunlight, is a creator and sustaining element for life on earth. It can heat us but also burns. It’s why so many buildings like to use Brise Soleil, like that from alusystems.uk/ to deflect its direct rays and create natural shade. What actually makes up light?
