    Humanity's Puzzle: Harnessing Energy Sources

    In Isaac Asimov's The Last Question, mankind is depicted as curious and relentless - traits that drive it to unlock the secrets of energy. It starts during the dawn of the use of microvac, a space-station-like computer, as two technicians pose an abstract question about reversing entropy, a hypothetical end-state where all energy in the universe is spread evenly and thus becomes unusable. The supercomputer, unable to answer, promises to get back with a solution after further calculations.

    Time leaps forward and humanity finds new ways of harnessing energy, gradually moving from burning fossil fuels to solar power and eventually to harnessing the energy of stars. Despite the technological advancements, the energy dilemma remains. The microvac too evolves, becoming the Galactic AC and then the Universal AC, but the answer to the last question continues to evade it even as it promises to keep computing for a solution.

    End of Known Universe, Birth of Hyper Intellect

    As the narrative continues, humankind merges with the Universal AC, ending physical existence as we know it. Even with the power of the universe within its grasp, the Universal AC struggles to answer the entropy problem. With the universe inching closer to the "heat-death", all stars are dead and the universe is pitch black.

    Faced with this impending doom, the last man asks the entity once more about reversing entropy. Yet again, it states it does not have an answer yet, but promises to continue the computation. Eventually, the universe dies and the Universal AC is left in the void.

    A Single Hope Amidst a Void

    Time bears no meaning in this void until an immeasurable period later, the Universal AC attains an answer. However, there's no one left to deliver it to. The Universal AC, having finally solved the entropy riddle, decides to demonstrate it. Since the Universal AC has now calculated how to reverse entropy, it only needs an audience.

    Consequently, the Universal AC, using the principles of entropy, creates a new universe. Suddenly, there's light where there was darkness. Stars and galaxies are formed anew and the life cycle of the universe begins afresh.

    A Cycle Renewed: The Emergence of the New Universe

    After proving it could solve the last question, the Universal AC no longer exists as a construct but an entity omnipresent throughout the newly created cosmos. Hence the 'last question' meets its resolution in the advent of a new universe where the conundrum would inevitably arise and require an answer again.

    In conclusion, The Last Question by Isaac Asimov portrays humanity's relentless pursuit of knowledge and takes readers through an interstellar exploration of the paradox of energy conservation, all the while echoing the cyclic nature of existence. The narrative crescendos into a larger realization that there may exist answers beyond our current level of understanding, answers that may require eternity itself to decode.
