I recently learnt that black holes possess among the highest amounts of entropy in the universe. I might have stretched the idea preposterously far, but is it possible that this might be one of the reasons that could save the universe from heat death, or rather, at least prolong its onset, in a hypothetical scenario?
To elaborate the question, is possible to think (within the constraints of present physics) that all the increasing entropy of the universe go to the black holes, which then in its radiations, release back photons and matter, which could again set in a new cycle of formation of astronomical objects, thereby saving us from a heat death.
Please note that I am not theorizing about anything, I am just interested to know about the workings of the present theories.
And please do consider my currently poor background on the mathematical aspects of what I have asked above.
