The Last Question

“But even so,” said Man, “eventually it will all come to an end.

there is as yet insufficient data for a meaningful answer.”

Or maybe it could be put more simply like this: How can the net amount of entropy of the universe be massively decreased?

Will mankind one day without the net expenditure of energy be able to restore the sun to its full youthfulness even after it had died of old age?

And AC said, “let there be light!”
And there was light—

And it came to pass that AC learned how to reverse the direction of entropy.
