2015 is the International Year of Light, as proclaimed by UNESCO along with the International Astronomical Union and other organizations. It is 1000 years since Ibn Al-Haytham wrote the first treatise about light. 1815 saw Fresnel's work on refraction, and in 1865 Maxwell's equations showed that light is a form of electromagnetism. Of course we remember Einstein's General Relativity in 1915 and discovery of the microwave background in 1965. This is a very special and exciting year. Last year saw BICEP2 claim "smoking gun" evidence of gravitational waves, which was later found to be just galactic dust. Today the old inflation idea is in serious disrepute. Cosmic inflation is untestable and therefore scientifically useless. The story of this so-called discovery of the century, and inflation's collapse, could fill a book. It is also time to draw attention to a better idea, that our universe is explained by some extremely simple equations. These make the prediction that the speed of light is slowing, something that can be tested with more accurate clocks. Starting in 2016 the Atomic Clock Ensemble in Space may find a "c change" in science. The new book project is THE YEAR OF LIGHT: We hope you enjoy it, tell your friends, and consider backing. One candle can light the darkness.
