In Nine Days Immersed in the Nature of Time (in Kyoto), Sarah Mackay embarks on a journey into the heart of one of the most mysterious and fundamental aspects of the universe—time. Set against the backdrop of Kyoto, a city where tradition and innovation coexist, Sarah delves into the quantum mechanics of time, seeking the final piece of the puzzle that will complete her groundbreaking theory of reality.

As Sarah navigates the lectures, she uncovers the profound implications of time dilation, the quantum Zeno effect, and the fluidity of time at the smallest scales. But this journey is not just scientific; it is deeply personal.

During this time she gets to know the true nature of the girl who was the cause of her breakup with Luigi, her former boyfriend. It turns out that Marta Castafiel has a very different take on time from the majority of the participants

Nine Days Immersed in the Nature of Time is a compelling exploration of the intersection between science, ethics, and personal struggle. It sets the stage for the final act of Sarah's journey, where the choices she makes will determine the future of the world she has come to understand so deeply.
