Don't read this KP (it's probably fine actually, I think you know it all already but just in case):
I just think "the whole universe is way older than we thought it was and we just missed that all of it is dying, coincidentally right now" is like. Nonsense. Thematically it's fine. As the solution to a big mystery you spent most of the game trying to figure out I thought it was extremely unsatisfying, especially considering that every other mystery in the game has an answer that I find very clever and fitting.
To be clear I'd have been fine with "this one specific star just happens to be dying right now". I don't think that twist scales up very well though.
That the game puts you in the position of thinking your goal is to stop the supernova and then learning you can't is one of the most clever things it does, though.
