After the heat death of the universe?

Question

I've always been intrigued, and a bit depressed, tbh, about the idea of the heat death of the universe. It's put a damper on my plans for immortality, thats for sure, an eternity with only high-energy photons for company could get dull. But now I hear that mayhap a quantum phase shift could change the universe something profoundly different in a finite time frame. Maybe within a mere 10^120 years! Is this true, and how does it work? What should I pack for the event?

Answer 1

I don't think you'll need a toothbrush. Your life will undergo a phase shift long before that!

Answer 2

Sounds like wishful thinking.
