So either modern science still has a long way to go in estimating the age of our universe OR the universe mentioned in vedas is the mother of all universes (a multiverse probably) including our own universe !!!
More interesting: Vedas also say that the average human life span in each yuga is as follows: Kali Yuga = 100 Years Dwapara Yuga = 200 Years Treta Yuga = 300 Years Satya Yuga = 400 Years ! Vedas are also implying by this that humans are not limited to planet earth nor to this universe alone.
So let us calculate how many years have passed since today started for Brahma.
But dont feel sad, let me promise you, this is a pretty long day.
Vedas say that before the creation of the universe Lord Vishnu is sleeping in the ocean of all causes.
His bed is a giant serpent with thousands of cobra like hoods. Brahma represents the universe which we all live in, and it is this Brahma who creates life forms. Vishnu is the personification of the eternal multiverse that exists forever without any beginning or end.
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 Maha Yugas).
So now, 1 day of Brahma = 14 Manvantaras (15 x 4 Yugas) = 994 Mahayugas 60 Yugas = 994 Mahayugas 6 Maha Yugas = 1000 So 1 day of Brahma = 1000 Maha Yugas = 4,320,000,000 years 1 night is again 1000 Maha Yugas = = 4,320,000,000 years 1 Complete day = day night = 8,640,000,000 years = 8.64 billion years Note that we are in the 7th Manvantara of this day.Vedas also say that Lord Hanuman will be the next Brahma.Well, thats something I have to do some research into later, the more things to think about, the more happy and occupied I am Coming back to a day of the Brahma. Vedas say that during the day Brahma is busy in creation of life and during the night all life he created is absorbed back into him!There are 360 days in a year for Brahma and we are in the first day of 51st year.
