Since the universe has been expanding faster than the speed of light, they calculate the universe to be some 90 billion lightyears across, but we can only EVER see some 14 billion lightyears, light from beyond that distance is receding too fast for ANY telescope even if the mirror was a light year across.
I think there is a question more intriguing than the age of the universe, instead, what happened BEFORE the big bang happened?

You should start a thread on it.

A Big Crunch?

I know, I know, the current consensus has the universe expanding for eternity, but I rather like Paul Steinhardt's Ekpyrotic model that proposes the Big Bang was caused by two parallel orbifold planes (branes) colliding in a higher-dimensional space. 'After several billion years, the universe has reached its modern state, and it will start contracting in another several billion years. Dark energy corresponds to the force between the branes, allowing for problems, like the flatness and monopole in the previous models to be fixed. The cycles can also go infinitely into the past and the future, and an attractor allows for a complete history of the universe.'

Yeah but the big crunch would happen after the BB. And of course there is I don't think, a shred of evidence the universe will collapse like a balloon with a hole in it.
One thing there is SOME evidence of, James Webb scope has found galaxies full grown and such at a time when the universe was 'only' a few hundred million years old but fully developed.
THAT has been interpreted as evidence our universe bumped into an old universe and some of their stuff mixed early on with out universe, sending in old galaxies that in OUR universe would take a billion years or more to be that big and active.
THAT implies the multiverse theory, an infinite or near infinite number of universes, bubbles if you will, each one with its own BB and such.
There is another theory that goes black holes starts a daughter universe by squirting into new spacetime and OUR universe came from a black hole in a parent universe squirting OUR BB to start us off.
