It is the only religion in which the time scales correspond, to those of modern scientific cosmology. Carl Sagan, the noted scientist says in relation to this, ''The Hindu religion is the only one of the world's great faiths dedicated to the idea that the Cosmos itself undergoes an immense, indeed an infinite, number of deaths and rebirths. Doing this simple maths gives the age of the cosmos to be 311 trillion years. 360 Brahma days constitute a Brahma year while 360 years represent the lifetime of Brahma which is the life of the cosmos. The day-night of Brahma together constitutes one Brahma day (8.64 billion years). There is an equivalent night-time of 4,320,000,000 years.
The reigning period of a manu is one manvantara which is 71.42 mahayugas. The kalpa is ruled by 14 manus in succession.
