There is a lot of speculation about the age of the Universe. Every little while, there is some new number, with language like “research suggests”, or “new evidence reveals”, etc. Numbers like 9 Billion years, 13.8 Billion years, etc., are thrown around. All speculative.
Then there’s the Biblican/Abrahamic version, which puts the age of the Universe to just a few thousand years.
There is authoritative information available, however, as to:
- How old is the Universe presently
- When will the Universe be dissolved
- What transitions take place in the Universe
- How big is the Universe
- One Universe or more than one Universe
According to the Srimad Bhagavatam https://vedabase.io/en/library/sb/3/11/advanced-view/, which gives information from the perspective of the Creator of the Universe, this particular universe has a total lifespan of approximately 311 Trillion Years. https://vedabase.io/en/library/bg/8/17/
Of that lifespan, approximately 50% is completed. So the present age of the Universe is 155 Trillion Years. http://www.krishna.com/how-he-creates
This Universe is one of innumerable, just like bubbles in the foam of the waves of the ocean.
There is a partial dissolution of the Universe periodically, every 4.32 Billion Years.
No matter how long all this may seem to be, in the context of eternity, this is but a flash in the pan.
Our Universe, The Source of the Universe is practically Infinite. We are each an infinitesimal part of The Infinite. What does that make us then? Why should we be attached to one particular situation on one particular planet in one particular Universe in one particular iteration of the Creation?
