Abstract

The speed of light and the lunar light year of the Earth have been used to calculate a centripetal
acceleration. The results align exactly with gravity at the surface of the Earth or 9.8m/s2
. It is thought that
the electromagnetic field of the Earth extends in a circular path to the far edges of the solar system and
the speed of light contributes to the centripetal acceleration experienced on Earth. The author concludes
that electromagnetism is the driving force of gravity in the near- and far-fields of the solar system.

Introduction

The first known lunar calendar was found at Warren Field in Scotland and has been dated
to c. 8000 BCE, during the Mesolithic period [1]. In ancient Egypt a lunar calendar was used
for religious and agricultural purposes. Present-day lunisolar calendars include the Chinese,
Hindu, and Thai calendars. Synodic months are 29 or 30 days in length, making a lunar
year of 12 months about 11 days shorter than a solar year. Some lunar calendars do not use
intercalation, such as most Islamic calendars. The Hebrew calendar uses the most common
form of intercalation which is to add an additional month every second or third year. In 1699,
Sir Isaac Newton proposed a new calendar based on lunar months [2]. Since each lunation is
approximately 29 1⁄2 days (29 days, 12 hours, 44 minutes, 3 seconds, or 29.530588 days),
it is common for the months of a lunar calendar to alternate between 29 and 30 days. Since
the period of twelve such lunations, a lunar year, is only 354 days, 8 hours, 48 minutes, 34
seconds.
