Time is calculated in so many ways in the Vedas, anything from the Mahakalpa , the breath of Mahavisnu to the Truti 30 thousandth of a second .
The engineer of this universe lives for 311 trillion years , and during this time, parts of the universe are rested , then rebooted .
As time goes on, four ages turn in cyclic movements .
Satya yoga , 1.8 million years , Treta yoga, 1.3 million years Dvarpa yoga 864,000 years ……Kali yoga 432,000 thousand years .
71 of these cycles turn, which represents the life on Manu , who is supervising the universe.
There are 14 Manus in one day of the Original engineer Lord Bramha .
Further
In the higher planetary systems, our six months is like their one day
And in the planetary systems of the supervising Demigods, our one year is equivalent to their day and night .
On our planet, we see time as relevant to individuals , for instance, a Mayfly lives for one night , or a dog lives 15 years a human 80 years , but they feel their lives full .
It was Albert Einstein who said time is relevant , and he is right, but the details of the differences and thd relativity are all calculated in the Vedas .
Another thing Einstein spoke on is the space time continuum , and the Vedas indicates that anything one does in a past , present, or future are interconnected and can instantly react with each other.
Thus, Karmic synchronicities are at play throughout the whole universal system .
