> Age of universe is 14Byears

It's age now. What will its age be when it is the relative equivalent of a 75yo human? A cosmic blink will be far longer than 7 months.

i don't think there really is such a relative equivalency. the universe according to best current understanding doesn't have anything which resembles human death to demarcate a lifetime. you could say 'heat death' but i dont think thats a strong comparison because, very much unlike human death, its a state which is approached asymptotically; the universe at heat death will look very much like the universe half way to, or even a millionth of the way to

I suppose the closest would be the point at which multicellular/intelligent life becomes impossible, or perhaps when all life becomes impossible. Stellar formation will end in about 100 trillion years, so that seems a good point.
