1. SCIENTIFIC BASIS OF YUGAS.
‘Yuga’ literally meaning ‘age’, is a concept in Hinduism which refers to a large period of time in the past, present, and future. (Sundarraj, 1997) In scientific terms, we can call Yuga an 'epoch'. Yuga is generally used to describe each of the four dharmic ages in Hinduism. The four ages are as follows: Satya Yuga, Treta Yuga, Dvapara Yuga, and Kali Yuga. (Atlantis and the Cycles of Time: Prophecies, Traditions, and Occult Revelations. Inner Traditions., 2011) A Yuga Cycle is a cyclic age completing all the four Yuga periods. The duration of each cycle lasts for 4,320,000 years. As a Yuga cycle passes through the earlier referred four Yugas, the length of each Yuga decreases by one-fourth. Similarly, mankind's overall morale and physical state also decrease at the same rate.
The duration of smallest of the four yugas ie, Kali Yuga is 432,000 years. The others are lengthier than Kali Yuga, with Dvapar Yuga two times, Treta three times and Satya four times this period. In total, they add up to 4.32 Million years. The shape of the Earth is not perfectly circular rather it is elliptical and in accordance with the scientific concept of Orbital Eccentricity (Orbital Eccentricity ), Earth's orbit changes its shape over time. The changing shapes may vary between low eccentricity ones as that of the circle, to shapes with high eccentricity as that of the ellipse. The point worth noting here is that such change in shapes happens over a span of 413,000 years - which is very near to the fundamental unit of a Yuga. Simply, we can say that the change in the shape of the Earth's orbit from circular to elliptical happens throughout one Yuga unit of time. Such a change in the orbital eccentricity has a significant impact on the climatic conditions, particularly temperature variations of the Planet.
According to Hindu Mythology, each Yuga should have a time of sunrise and sunset taking nearly 10% of its time which is 43,000 years. This phenomenon is explained by the concept of Axial Tilt, (Hocken) which refers to the variation in the angle of Earth's axis. The concept says that the Earth does not rotate in space like an ideal sphere, rather it inclines/tilts like a turning top offering ascend to seasons. Here, the amazing point is that the angle of the inclination or tilt does not remain same, it, however, takes roughly 41,000 years to move between an inclination or tilt of 22.1° & 24.5° and reverse prompting huge climatic change on the Earth.
