Have any galaxies actually faded into darkness before? Considering our galaxy is basically the same age as the universe I find it hard to believe any galaxy has just run out of energy and gone dark.
I suppose you could interpret it as the galaxy leaving the observable universe, but that doesn’t have the same meaning to me.
Yes absolutely. A galaxy is considered 'dead' after it can no longer generate new stars. Here are a couple of articles:
