I suppose this time is expressed in earth years? Or what would this duration mean on a Universe scale? Also given the nature of space-time (the time and gravity relationship) wouldn't time be almost still once, let's say, year 10⁷⁷ is reached?

Isn't time relative?

If you were in a place where time was still you'd have no idea it were the case. Time would still tick at one second per second. You could only tell when you looked at some other object/patch of space that had a different ticking clock.

Time is relative, absolutely (I had to do it, sorry). I guess in these articles they mean 10^77 years for an observer on earth. My understanding is if I was, somehow, waiting inside a black hole it would take much less time for me to observe the universe decaying. And if i'm not mistaken, then I wonder what does that mean for the universe as a whole. Maybe the question doesn't make sense when taking the whole universe as being the "observer"...
