Source? I don't think physicists agree. For a while there was an idea getting popularity, that black holes erase information, but in the recent year I've seen some articles and youtube videos (didn't actually care to read/watch) with titles saying otherwise.
To my understanding, the idea behind the heat death of the Universe is that nothing interesting happens anymore, not that there is absolutely nothing.
