02 May Age of Universe
While the West WAS still thinking, perhaps, of 6,000 years old universe – India was already envisioning ages and eons and galaxies as numerous as the sands of the Ganges. The Universe so vast that modern astronomy slips into its folds without a ripple.
Universe is beginning less and endless. It subscribes to the theory of manifestation and non-manifestation of the universe, of evolution of cosmic energy into names and forms and its involution.
The Puranas describe time units from the infinitesimal truti, lasting 1/1,000,0000 of a second to a mahamantavara of 311 trillion years.
Hindu sages describe time as cyclic, an endless procession of creation, preservation and dissolution. Scientists such as Carl Sagan have expressed amazement at the accuracy of space and time descriptions given by the ancient rishis and saints, who fathomed the secrets of the universe through their mystically awakened senses.
Hinduism teaches that the material world is created not once but repeatedly, time and time again. Additionally, this universe is considered to be one of many, all enclosed “like innumerable bubbles floating in space.” Within this universe, there are three main regions: the heavenly planets, the earthly realm and the lower worlds.
A universe endures for about 4,320,000,000 years(one day of Brahma, the creator or Kalpa) and is then destroyed by fire or water elements. At this point, Brahma rests for one night, just as long as the day.
This process, named Pralaya (literally especial dissolution in Sanskrit, commonly translated as Cataclysm), repeats for 100 Brahma years (311 Trillion, 40 Billion Human Years) that represents Brahma’s lifespan. Brahma is regarded as a manifestation of Brahman as the creator.
Vishnu Purana describes Vishnu as creator, sustainer, destroyer and then re-creator of the universe. This process takes place over a vast period of time called a Kalpa (nearly 9 billion years). The creation, sustaining and destruction of the universe is also told in the stories about Shiva, who is often shown as ‘Lord of the Dance’.
1 Mahayuga = 4,320,000 years
1 Manvantara = 71 Mahayugas
1 day of Brahma = 14 Manvantaras = 994 Mahayugas
Now a small addition here, Vedas also say that before and after each Manvantara there is a gap equivalent to 4 Yugas (Not MahaYugas).
So now, 1 day of Brahma = 14 Manvantaras + (15 x 4 Yugas)
= 994 Mahayugas + 60 Yugas
= 994 Mahayugas + 6 MahaYugas = 1000
So 1 day of Brahma = 1000 MahaYugas = 4,320,000,000 years
1 night is again 1000 MahaYugas = = 4,320,000,000 years
1 Complete day = day + night = 8,640,000,000 years = 8.64 billion years
Meanwhile, the maximum number the roman numerals were representing was 3999 = MMMCMXCIX, because there is no letter for number beyond that.
