In the attempt to secularize the calendar, many, if not most academics use the appending 'CE' for 'Common Era' but they fail to acheive their goal because the zero date is the year of the birth of Christ as most traditionally calculated. So here is a suggestion: change the zero year to the start of the modern era. But what year is that? And why the modern era? The modern era is characterized by a change of mental attitudes about the knowlege and authority of writers long dead from the ancient world. The idea of learning in almot all of the pre-Modern world was to bring up some treatise from a learned ancient and glean knowlege from it. The modern era thought began with mathematical and scientific approaches and said 'What can we most certainly know about a subject' then built on that. The cosmology of the modern era was almost completely reversed from the middle ages and the ancient world. This is what began to shape the world as we know it today. But what event would be the best reference to date the modern era from? The fall of Constantinople? That is more of a symbolic importance, and had little real impact on the modern world. The discovery of the Americas by Columbus? That really didnt change ancient cosmolgy to modern, though it did establish the economic domination of the Western European nations till the end of the Twentieth century, but that affect is now almost completely passed as evidence of China India and the rise of the USA have demonstrated, all nonEuropean nations. The heliocentric view of the universe? Another mistake in concept of the universe since there really is not ca enter of the universe, except perhaps where the Big Bang took place. This was more derivative than causal and was largely ignored by most astronomers till Gallileo, at least that is my impression. The development of astronimical navigation? Well, the impact of that was limited to commerce mostly and is again more derivative of other major changes rather than being the root change to modern cosmology itself. I think the production of the first printing press in 1468 is the best event to deliniate the beginning of the Modern Cosmology. This development led to an explosion of learning as books became far more affordable and easier to print. Books became the posession of anyone who wanted to read them enough to save up some paltry sum and buy them. The development of the printing press allowed the mass production of astronomical tables that allowed for astronomical navigation. Ubiqitous tomes of knowlege made universal education possible, allowed for easier and more acurate record keeping, and unleashed the modern mind to think of new worlds, new ideas and new ways of life. The printing press gave us an explosion of learning, creativity and accuracy far surpassing the pre-modern times. So, without further explanation, I present to you all the year 544 M.E., Modern Era.
