Escape the universe into what? And who are the "we" who will escape trillions of quadrillions of years hence? Time changes us, whether we like it or not. Eternity is an abstract concept that will never be realised. What people desire by all these wishes to extend life is continuity, yet given enough period of change, there won't be much continuity to savour. People imagine they are only their thoughts and memories but those very things are dependent not just on our bodies but also our environments. Given enough change in the latter two then our thoughts and memories will become so discordant that the "you" will no longer be continuous. In effect: death, which you tried so hard to avoid.
