In "Caught in Time" by Diana Gabaldon, a profound conversation unfolds about the nature of existence and belief. One character asserts that nothing is truly lost but merely transformed. This idea resonates with the first law of thermodynamics, which states that energy cannot be created or destroyed, only changed. The protagonist reflects on this scientific principle, highlighting the interplay between science and personal faith.

However, the response challenges the reduction of such an idea to scientific terms, suggesting that the essence of what is lost speaks more to a matter of faith than a mere scientific explanation. This exchange underscores the complexities of understanding life and change, merging the worlds of science and spirituality in a thought-provoking way.
