So as per the vedas, the current age of the universe is 155,521,972,944,456 Years which is about 155,522 billion years !!! Modern day science has been able to predict age of our universe to be only about 15-20 billion years! Moreover Since we are in the first day of 51st year of Brahma, almost equal amout of time has to pass before this universe ends!!
So either modern science still has a long way to go in estimating the age of our universe
the universe mentioned in vedas is the mother of all universes (a multiverse probably) including our own universe !!!
